For most greenhouse growers, I’d start with the iLIVING 16-Inch Wall-Mounted Shutter Exhaust Fan: its thermostat and variable speed control offer a useful balance of airflow and hands-off temperature management. The CAMMOO 20-Inch stands out for growers who want temperature and humidity controls, while the VIVOSUN AeroWave E6 Gen2 suits compact spaces that need moving air rather than full-room exhaust. The main choice is between a wall-mounted fan that exchanges hot air and smaller clip-on fans that circulate air around plants; size, controls, noise, and installation all affect the fit. A larger fan may move more air, but it also needs a suitable opening and mounting location. Read on for the full comparison and guidance on matching a fan to your greenhouse.

Key Takeaways
- The iLIVING 16-inch model leads as an all-around exhaust option because it pairs a practical wall-mounted format with thermostat and variable speed controls.
- The CAMMOO 20-inch adds humidity control, a useful distinction for growers managing damp conditions as well as heat, though its larger format requires more space.
- VEVOR’s 10-, 12-, and 16-inch models provide a range of exhaust sizes; choose by opening dimensions and ventilation needs rather than assuming the biggest model is best.
- Amico’s 10-inch model combines a remote, nine-speed DC motor, and stated 1,000 CFM, while its 12-inch option emphasizes thermostat control and a smaller form factor.
- Clip-on fans from PGQUY, VIVOSUN, Erifyng, and Tonree circulate air locally; they complement exhaust fans but are not direct substitutes for exchanging greenhouse air.

More Details on Our Top Picks
iLIVING 16-Inch Wall-Mounted Shutter Exhaust Fan with Thermostat and Variable Speed Controller
The iLIVING 16-inch is my most balanced pick for a greenhouse that needs meaningful exhaust capacity without moving up to a large 20-inch unit. Its stated 1,200 CFM, thermostat, and three speeds let growers tailor ventilation to changing heat conditions instead of running a single fixed setting. Automatic shutters close when the fan stops, while the galvanized frame and aluminum blades suit a damp growing space better than an exposed, unprotected assembly. Compared with the Amico 12-inch, this model offers a larger fan and a simpler three-speed control setup, but the Amico adds more speed steps and a lower listed noise level. The tradeoff here is wall-only mounting and noise listed below 65 dB, so I would choose it for practical exhaust rather than a quiet space or flexible installation.
Pros:- 1,200 CFM capacity suits ventilation needs beyond compact grow spaces.
- Thermostat and three speeds provide temperature-based operation and airflow adjustment.
- Automatic shutters close when the fan is off.
- Galvanized steel frame and aluminum shutters and blades are suited to humid environments.
Cons:- Wall mounting limits placement to a suitable opening.
- Noise is listed as less than 65 dB, which may be noticeable in nearby work areas.
Best for: Greenhouse growers who want thermostat-controlled exhaust and three speed choices in a mid-size, wall-mounted fan.
Not ideal for: Growers without a suitable wall opening or those prioritizing lower noise and finer speed adjustment.
- Airflow:1,200 CFM
- Fan size:16 inches
- Coverage area:Up to 1,800 sq ft
- Voltage:115 V
- Power:97 W
- Speeds:3
- Temperature control range:32–130°F
- Noise level:Less than 65 dB
- Materials:Galvanized steel frame, aluminum shutters and blades
Our verdict“Choose this iLIVING if you want a capable mid-size greenhouse exhaust fan with thermostat control and can accommodate wall mounting.”
VEVOR 16-Inch Wall-Mounted Shutter Exhaust Fan
The VEVOR 16-inch is appealing when a grower wants a 16-inch shutter fan and is focused on its advertised airflow, but its product data makes this a less certain choice than the iLIVING 16-inch. VEVOR lists 2,000 CFM in the specifications and up to 2,438 CFM in the description; power and speed figures also conflict. That makes direct capacity comparisons difficult, so I would not size a greenhouse around the higher claim without confirming the specification with the seller. Its steel housing, automatic shutters, and included prewired cord are practical advantages, while the missing speed controller means fewer ready-to-use control options than either iLIVING model. It makes the most sense for buyers who can verify the figures and are comfortable arranging their own control setup; the data uncertainty is the central tradeoff.
Pros:- The listed airflow is 2,000 CFM, with a higher capacity claim in the description.
- Automatic shutters close when the fan is off to help limit rain and debris entry.
- Steel housing is described as suitable for damp conditions.
- A prewired power cord is included.
Cons:- Airflow, motor power, and motor speed figures conflict across the product information.
- A speed controller and power plug are not included, limiting out-of-box control options.
- Its 65 dB noise rating may be noticeable in a small greenhouse or nearby work area.
Best for: Greenhouse owners seeking a 16-inch shutter fan who can confirm the correct airflow rating and do not need an included speed controller.
Not ideal for: Buyers sizing ventilation precisely, or growers who want thermostat or variable-speed controls included with the fan.
- Blade size:16 inches
- Airflow capacity:2,000 CFM in specifications; up to 2,438 CFM in description
- Motor power:77 W in description; 115 W in specifications
- Voltage:120 V
- Motor speed:1,450 rpm in specifications; 1,500 rpm in description
- Noise level:65 dB
- Housing and blade materials:Steel housing, plastic blades
- Dimensions:8 × 18.9 × 18.9 inches
Our verdict“Consider this VEVOR if you can verify its specifications and value the stated airflow over integrated temperature and speed controls.”
Amico 12-Inch Shutter Exhaust Fan with Thermostat, 8 Speeds, 1282 CFM
For a smaller greenhouse where controllability matters as much as raw exhaust, the Amico 12-inch offers a distinctive mix: eight speeds, thermostat operation, and a listed 50 dB noise level. Its 1,282 CFM rating is slightly above the iLIVING 16-inch’s stated 1,200 CFM, though the figures alone do not establish how either fan will perform in a particular greenhouse or duct layout. The brushless DC motor is rated at 25 W, and the prewired 120V plug can simplify the electrical setup compared with the VEVOR 16-inch, which lacks an included speed controller. Its smaller diameter may suit tighter openings, but installation still requires a wall or window cutout, and the thermostat probe wire is only three feet long. I’d favor it for closer control, not for the broadest or simplest installation.
Pros:- Eight speeds allow more airflow adjustment than the three-speed iLIVING models.
- Thermostat supports automatic temperature-based operation.
- Listed noise level is 50 dB.
- Prewired standard plug can simplify connection to a compatible outlet.
Cons:- Wall or window installation requires a suitably sized opening.
- The thermostat probe wire is 3 feet long, which can restrict sensor placement.
- Its 12-inch size is less suited to buyers who want a larger-diameter exhaust fan.
Best for: Growers with a compact greenhouse who want thermostat automation, multiple speed steps, and a lower listed noise level.
Not ideal for: Owners of large greenhouses seeking the highest stated airflow, or installers who need a long thermostat-probe reach.
- Fan diameter:12 inches
- Airflow capacity:1,282 CFM
- Motor:25 W brushless DC
- Voltage:120 V
- Speeds:8
- Noise level:50 dB
- Coverage:Up to 1,600 sq ft
- Mounting:Wall mount
- Warranty:3-year limited coverage
Our verdict“Pick the Amico for a compact installation where quieter listed operation and eight-speed thermostat control matter more than a larger fan diameter.”
iLIVING 20-Inch Wall-Mounted Shutter Exhaust Fan with Thermostat and Variable Speed Controller
The iLIVING 20-inch is the lineup’s clearer choice when a greenhouse needs a substantial step up in exhaust capacity: its stated 3,368 CFM and coverage claim of up to 5,000 square feet exceed the 16-inch iLIVING’s 1,200 CFM rating by a wide margin. Thermostat control, three speeds, and automatic shutters give growers a straightforward way to regulate ventilation without adding a separate controller. The galvanized frame and aluminum shutters and blades are useful material choices for humid conditions. Compared with the CAMMOO 20-inch, however, it has a lower stated airflow and only three speeds; CAMMOO lists 4,000 CFM and ten speeds, along with temperature and humidity control. The iLIVING’s tradeoffs are its 26-pound weight, wall-only installation, and noise listed up to 69 dB. It is for scale, not quiet or highly granular control.
Pros:- 3,368 CFM rating is a substantial step up from the iLIVING 16-inch model.
- Thermostat and three speeds support temperature-based ventilation control.
- Automatic shutters open and close with fan operation.
- Galvanized steel frame and aluminum shutters and blades are suited to humid environments.
Cons:- Wall mounting requires a large, suitable opening.
- Noise is listed at up to 69 dB.
- Three speeds offer less adjustment than the CAMMOO 20-inch’s ten-speed control.
Best for: Owners of large greenhouses who need high stated airflow, thermostat operation, and a robust wall-mounted exhaust unit.
Not ideal for: Small greenhouse owners, buyers without a suitable wall opening, or growers who need humidity-based automation or many speed steps.
- Fan diameter:20 inches
- Airflow capacity:3,368 CFM
- Coverage area:Up to 5,000 sq ft
- Voltage:115 V
- Power:253 W
- Motor power:1/5 HP
- Speeds:3
- Temperature control range:32–130°F
- Noise level:Up to 69 dB
Our verdict“Choose this iLIVING for a large greenhouse needing high-capacity, thermostat-controlled exhaust, but look at the CAMMOO if humidity automation and finer speed control matter more.”
CAMMOO 20-Inch Exhaust Fan with Temperature, Humidity, and Speed Control
The CAMMOO 20-inch stands apart from both iLIVING exhaust fans by pairing a stated 4,000 CFM with ten speeds and automatic responses to temperature and humidity. That broader control range can suit growers managing both heat and moisture, while timer and cycle modes add scheduling options. Its 70 W brushless EC motor is listed alongside the 4,000 CFM capacity, and the six-inch touchscreen gives the controls a more central role than the simpler controller setups on the iLIVING 20-inch. Automatic shutters close when the fan stops, helping keep dust and debris out. The tradeoffs are a wall-mounted, corded installation and a reliance on the included touchscreen and its 9.84-foot control cable. The product details do not provide a noise rating or coverage area, so buyers needing those figures for planning should check before choosing it.
Pros:- Stated 4,000 CFM capacity exceeds the iLIVING 20-inch’s listed airflow.
- Ten speeds offer finer adjustment than the three-speed iLIVING models.
- Temperature and humidity control, timer, and cycle modes support automated operation.
- Automatic shutters close when the fan stops.
Cons:- Wall mounting requires a suitable opening and installation location.
- Corded electric power limits placement to reach of a compatible connection.
- The provided specifications do not list a noise level or coverage area.
Best for: Greenhouse growers who want one exhaust fan to respond to temperature and humidity, with multiple speeds and timer or cycle modes.
Not ideal for: Buyers who need a stated noise rating or coverage area before sizing equipment, or those unable to use a wall-mounted corded fan.
- Airflow capacity:Up to 4,000 CFM
- Fan diameter:20 inches
- Motor type:Brushless EC motor
- Power:70 W
- Voltage:120 V
- Speeds:10
- Controller:6-inch touchscreen
- Control cable length:9.84 feet
- Special features:Temperature and humidity control, timer and cycle modes, automatic shutters
Our verdict“Choose the CAMMOO if temperature-and-humidity automation and ten speeds outweigh the need for published noise and coverage figures.”
PGQUY 5-Inch Grow Tent Clip-On Fans, 2-Pack
For growers who need air movement inside a tent rather than heat exhaust through a wall, this two-fan set covers two spots with one purchase. The clamps attach to tent poles, and three speeds let me choose gentler circulation for seedlings or stronger airflow around mature plants. Its IP54-rated design offers resistance to dust and water exposure, while the brushless motors and 8-foot USB cords suit an indoor setup. Compared with the VIVOSUN AeroWave E6 Gen2, PGQUY is simpler and offers two fans, but it lacks oscillation, app control, and the E6’s stated 320 CFM airflow. These are circulation fans, not substitutes for a wall exhaust fan such as the VEVOR 10-Inch. I’d skip them if you need automated air exchange or broad, moving coverage.
Pros:- Two clamp-mounted fans can direct airflow to separate areas of a tent
- Three speeds allow adjustment for different plants and growth stages
- IP54 rating resists dust and water exposure in indoor growing spaces
- Eight-foot USB cords offer flexibility when positioning near tent poles
Cons:- No oscillation, so airflow stays aimed in a fixed direction
- Designed for indoor use rather than outdoor greenhouse exposure
- Does not provide a listed CFM figure for planning room-wide air exchange
Best for: Grow-tent owners who want two independently positioned fans for basic circulation around plants.
Not ideal for: Greenhouse growers who need to exhaust hot, humid air outdoors or want oscillation and app-based controls.
- Fan size:5 inches
- Number of fans:2
- Mounting:Clip-on/clamp
- Speed settings:3
- Motor:Brushless DC
- Noise level:39 dB
- Cord length:8 feet
- Ingress protection:IP54
Our verdict“Choose this two-fan set for straightforward tent circulation, but pick an exhaust model for removing greenhouse heat and humidity.”
Ehiair 8-Inch Shutter Exhaust Fan with Thermostat and Remote Control
The Ehiair stands out among these picks for combining wall exhaust with temperature control in a compact 8-inch format. Its listed 760 CFM and three speeds provide a defined airflow option for a smaller greenhouse, while the thermostat and timer can reduce the need for manual adjustments. A remote with a stated 66-foot range adds convenience when the fan is mounted high or out of reach. Compared with the VEVOR 10-Inch 820 CFM, Ehiair offers less listed airflow but adds temperature automation, a timer, and automatic shutters that help block rain, dust, wind, and insects when stopped. The tradeoff is installation: it needs a suitable wall opening, and its short power and controller cables may constrain placement. I would choose a circulation clip fan instead if I only need air movement among plants.
Pros:- Listed 760 CFM airflow with three speed settings
- Thermostat, timer, and remote provide several ways to manage ventilation
- Automatic shutters help keep weather, dust, and insects out when off
- Galvanized steel frame and aluminum blades are suited to utility-space use
Cons:- Wall installation requires a compatible opening
- Power cord and fan-to-controller cable may limit mounting choices
- Listed airflow is lower than the VEVOR 10-Inch model’s 820 CFM
Best for: Small-greenhouse owners who want wall-mounted exhaust with thermostat operation, a timer, and remote adjustments.
Not ideal for: Growers without a suitable wall opening or those needing longer cables, higher stated airflow, or a portable clip-on fan.
- Airflow:760 CFM
- Fan size:8 inches
- Motor power:26 W
- Voltage:120 V AC
- Speeds:3
- Temperature range:32°F–140°F
- Timer:Up to 18 hours
- Remote range:66 feet
- Mounting:Wall mount
Our verdict“Pick the Ehiair for a smaller greenhouse where automatic temperature control matters more than maximizing listed airflow.”
VEVOR 12-Inch Wall-Mount Shutter Exhaust Fan with Variable Speed Controller
This VEVOR is the larger wall-mounted choice for buyers who want variable-speed control and automatic shutters without moving up to the 16-inch options elsewhere in the roundup. Its 12-inch frame and steel housing suit a fixed greenhouse or utility-room installation, while the prewired cord can simplify the electrical setup. The major qualification is the product’s conflicting airflow data: the title and description state 1,347 CFM, while the specifications list 1,100 CFM; power is also shown as both 40 W and 58 W. I would not size a greenhouse ventilation plan around the higher figures without clarification. Compared with the Ehiair 8-Inch, this fan has a larger form and variable speed control, but lacks the listed thermostat, timer, and remote. Its 60 dB rating also makes it a less appealing choice near quiet work areas.
Pros:- Variable-speed controller supports airflow adjustment
- Automatic shutters close when the fan is off to help block rain and debris
- Steel housing and prewired power cord suit fixed installations
- 12-inch size offers a middle ground between the Ehiair 8-Inch and larger wall fans
Cons:- Airflow is listed as both 1,100 and 1,347 CFM
- Power is listed as both 40 W and 58 W
- Listed 60 dB noise level may be intrusive in nearby work areas
Best for: Greenhouse owners seeking a 12-inch shutter exhaust fan with variable speed control who can verify airflow and power requirements before sizing.
Not ideal for: Buyers who need dependable published airflow figures, quiet operation, or built-in thermostat and timer functions.
- Fan size:12 inches
- Airflow:1,100 CFM in specifications; 1,347 CFM in title and description
- Motor:AC, 1,600 RPM
- Power:58 W in specifications; 40 W in description
- Voltage:120 V
- Noise level:60 dB
- Mounting:Wall mount
- Material:Alloy steel
- Dimensions:14.96 x 14.96 x 7.09 inches
Our verdict“Consider this 12-inch VEVOR if variable speed and shutter protection appeal, but confirm its airflow and power figures before buying.”
VIVOSUN AeroWave E6 Gen2 6-Inch Oscillating Grow Tent Clip Fan
For tent growers who need moving circulation rather than wall exhaust, the AeroWave E6 Gen2 is the most adjustable clip fan in this group. Its stated 320 CFM, ten speeds, and five-level oscillation offer more ways to spread airflow than the fixed-direction PGQUY two-pack. The EC motor’s 33 dB(A) rating also makes it a quieter-specified option for indoor growing. Without the app, though, only five speed levels are available; Wi-Fi control requires a compatible VIVOSUN GrowHub, which adds a separate dependency. The obstacle-detection feature can retract oscillation when something blocks its movement, while IP54 protection and a padded clamp suit humid tent conditions. I would skip it if the goal is to pull hot air out of a greenhouse: unlike the VEVOR 10-Inch, it is a clip-on circulation fan, not a shutter exhaust unit.
Pros:- Stated 320 CFM airflow with five-level automatic oscillation
- Ten speed settings are available with app connection
- 33 dB(A) noise rating and 12 W power draw
- IP54 protection and rubber-padded clamp suit humid grow spaces
Cons:- Only five speed levels are available without the app
- Wi-Fi and app control require a compatible VIVOSUN GrowHub
- Clip-on circulation does not replace a greenhouse exhaust fan
Best for: Indoor growers who want quiet, adjustable oscillating airflow clipped to a tent pole and value the option of app control.
Not ideal for: Greenhouse owners needing wall-mounted exhaust, or buyers who want all speed settings without a separate GrowHub.
- Airflow:320 CFM
- Fan size:6 inches
- Speeds:10; 5 without app connection
- Modes:Normal and natural
- Oscillation:5-level automatic oscillation
- Motor:EC motor
- Noise level:33 dB(A)
- Power:12 W
- Ingress protection:IP54
Our verdict“Choose the AeroWave E6 Gen2 for quiet, oscillating tent circulation, not for exhausting greenhouse air outdoors.”
VEVOR 10-Inch Wall-Mount Shutter Exhaust Fan, 820 CFM
The VEVOR 10-Inch is a straightforward pick for growers who want fixed wall exhaust with a stated 820 CFM and do not need built-in speed choices. Its galvanized steel frame and aluminum blades suit a permanent installation, and the thermal protection and permanently lubricated motor are practical features for a fan expected to run regularly. Compared with the Ehiair 8-Inch, it lists more airflow but gives up thermostat control, a timer, and a remote; unlike the variable-speed VEVOR 12-Inch, it runs at one speed. That simplicity also means the plug and speed-control switch are not included, so buyers must plan for the electrical connection rather than assume it is ready to plug in. I would avoid it when adjustable ventilation or automated temperature response is a priority.
Pros:- Stated 820 CFM airflow for removing heat, humidity, odors, and dust
- Galvanized steel frame and aluminum alloy blades
- Thermal protection and permanently lubricated motor
- Single-speed design keeps operation straightforward
Cons:- Only one speed, with no listed variable-speed control
- Plug and speed-control switch are not included
- No thermostat or timer for automatic ventilation
Best for: Greenhouse owners who need a fixed 10-inch exhaust fan with stated 820 CFM airflow and are prepared to source the electrical connection.
Not ideal for: Buyers seeking multiple speeds, included plug and switch, or thermostat-based ventilation control.
- Fan size:10 inches
- Airflow:820 CFM
- Motor:AC, 1,650 RPM
- Power:45 W
- Voltage and frequency:120 V, 60 Hz
- Noise level:50 dB
- Number of speeds:1
- Mounting:Wall mount
- Frame and blade materials:Galvanized steel frame; aluminum alloy blades
Our verdict“Pick this VEVOR for simple, fixed-speed wall exhaust if you can handle the separate electrical setup.”
VIVOSUN AeroWave D4 Grow Tent Clip Fan with Detachable Hook, 4″ Fan, 1-Pack
The VIVOSUN AeroWave D4 is a small circulation fan for growers who need to move air around a specific canopy, not exhaust heat from the greenhouse. Its 85 CFM output and compact 4-inch size suit a tent corner or a small propagation area, while the stated 35 dBA noise level makes it quieter on paper than the paired Erifyng fans. Three speeds and an adjustable cover let me choose between a broader breeze and a more focused stream.
Its detachable hook and several mounting options give it more placement flexibility than a basic clip fan, but the magnetic plate for wall mounting is not included. Compared with the Tonree two-pack, this is a single, lower-capacity unit; its advantage is quiet, targeted airflow, not broad coverage. I would skip it as a primary ventilation solution for a larger greenhouse, since it does not replace an exhaust fan.
Pros:- Stated 35 dBA operation suits noise-sensitive indoor grow spaces.
- Adjustable front cover supports broad or focused airflow.
- Detachable hook and multiple mounting options offer flexible placement.
- USB power and 4-watt draw suit compact tent setups.
Cons:- 85 CFM is unlikely to provide enough airflow for a larger growing space.
- Magnetic plate needed for wall mounting is not included.
- One fan provides less coverage than the Erifyng or Tonree two-packs.
Best for: Indoor growers who want quiet, targeted airflow around a small tent canopy, seedlings, or a propagation shelf.
Not ideal for: Growers ventilating a large greenhouse or seeking a complete exhaust setup; 85 CFM is limited, and this is a single circulation fan.
- Fan size:4 inches
- Airflow capacity:85 CFM
- Speed settings:3
- Maximum speed:3500 RPM
- Noise level:35 dBA
- Power:4 watts
- Power source:USB, 5 volts
- Mounting:Clip-on, with detachable hook and additional placement options
Our verdict“Choose the AeroWave D4 for quiet, localized tent circulation, not for exhausting a greenhouse or moving air across a large area.”
Erifyng 5-Inch Dual Clip-On Grow Tent Fans
The Erifyng dual-fan set makes sense when one breeze leaves stagnant pockets around plants: two separate heads can target different areas without depending on oscillation. Each fan has three speeds, a ball joint for aiming, and a clamp that fits poles or edges from 0.5 to 2 inches. The IP54 water-resistance rating is a useful advantage in humid growing conditions compared with the VIVOSUN AeroWave D4, which is described for indoor use but has no water-resistance rating listed.
Long, individual 8-foot cords give more placement reach, but each fan needs its own power connection through an adapter, so cable routing becomes part of the setup. The airflow claim reaches 330 CFM, though the listing’s noise figures conflict: it gives a 37–53 dBA range in the description and 45 dB in the specifications. I’d choose this over the single-fan VIVOSUN when two-point coverage matters, but not if quiet operation is the main priority.
Pros:- Two fans allow airflow to reach separate areas of the growing space.
- Ball joints and clamps support flexible aiming and mounting.
- IP54 water resistance is suited to humid grow environments.
- Each fan has an 8-foot cord for flexible placement.
Cons:- Both fans require power, adding cords and adapter connections to the setup.
- Noise figures conflict between the product description and specifications.
- The listing does not clearly resolve the stated material as plastic or metal.
Best for: Growers with a tent or compact greenhouse who need two independently aimed fans and can route power to both mounting points.
Not ideal for: Buyers seeking a single low-clutter installation or dependable noise specifications; two powered units also mean more cords to manage.
- Quantity:2 fans
- Fan size:5 inches
- Maximum airflow:330 CFM
- Speed settings:3
- Maximum speed:3700 RPM
- Water resistance:IP54
- Clamp fit:0.5–2-inch poles or edges
- Cord length:8 feet per fan
Our verdict“Pick the Erifyng set when separately aimed airflow and moisture resistance matter more than a tidy, single-cord installation.”
Amico 10-Inch Shutter Exhaust Fan with Remote, 9-Speed DC Motor, 1000 CFM
Unlike the clip-on VIVOSUN AeroWave D4, the Amico 10-inch shutter fan is built to remove warm greenhouse air rather than circulate it around a plant canopy. Its stated 1000 CFM airflow, nine speeds, and remote control give growers more adjustment than a basic fixed-speed exhaust fan; the 1–8-hour timer can also run ventilation for a set period without leaving it on indefinitely. Gravity-operated louvers close when the fan stops, helping limit exposure to weather, dust, insects, and cold air.
The tradeoff is installation: this unit needs a cut wall opening, so it is not a portable or clip-on option. Compared with the iLiving 12-inch fan, the Amico offers remote operation and more speed steps, while the iLiving adds thermostat-based automatic cycling. The Amico is the better match for manual control from nearby, but I would choose the iLiving when temperature-triggered operation matters more than a remote.
Pros:- Stated 1000 CFM capacity is suited to exhaust ventilation rather than local circulation.
- Nine speeds and remote control allow adjustments without reaching the fan.
- Timer can be set from 1 to 8 hours.
- Gravity-operated louvers help close the opening when the fan is off.
Cons:- Wall installation requires cutting an opening.
- Remote control is needed to change settings.
- Unlike the iLiving 12-inch model, it has no listed thermostat control.
Best for: Greenhouse owners who want a wall-mounted exhaust fan with remote speed adjustment, a timer, and closing louvers.
Not ideal for: Renters, temporary setups, or growers who cannot cut a wall opening; skip it if automatic thermostat cycling is a priority.
- Fan size:10 inches
- Airflow capacity:1000 CFM
- Motor power:13 watts
- Speed settings:9
- Noise level:42 dB
- Control:Remote control
- Timer:1–8 hours
- Installation:Wall mount, plug-in
Our verdict“Choose the Amico for adjustable, timer-controlled wall exhaust, especially when remote operation matters more than automatic temperature control.”
iLiving 12-Inch Wall-Mounted Shutter Exhaust Fan with Thermostat and Variable Speed Control
The iLiving 12-inch shutter fan stands out for growers who want ventilation to respond to greenhouse temperature instead of relying on constant manual adjustments. Its thermostat can cycle the fan within a 32–130°F range, and the listed capacity is 960 CFM for spaces up to 1,400 square feet. Automatic aluminum shutters open with operation and close afterward, making this a more weather-conscious exhaust setup than the clip-on Tonree fans, which circulate air but do not remove it from the greenhouse.
Compared with the Amico 10-inch fan, the iLiving trades remote control and nine speed steps for thermostat control and a larger stated coverage area. Its three speeds offer less fine adjustment, and the up-to-65 dB noise level is worth weighing if the greenhouse sits near living areas. Installation also requires hardwiring, unlike the Amico’s plug-in setup. I’d favor it for permanent, temperature-managed ventilation, not for a quick or portable installation.
Pros:- Thermostat can cycle ventilation across a broad 32–130°F range.
- Listed 960 CFM capacity and coverage up to 1,400 square feet suit larger spaces.
- Automatic shutters close when the fan is off.
- Galvanized steel frame and aluminum shutters and blades are specified.
Cons:- Requires hardwired electrical installation.
- Noise is listed at up to 65 dB.
- Three speeds offer fewer adjustment steps than the Amico 10-inch model’s nine.
Best for: Owners of a permanent greenhouse who want a wall exhaust fan to cycle automatically as temperatures change.
Not ideal for: Renters, DIYers avoiding hardwiring, or growers placing a fan near quiet areas who are concerned about its listed noise level.
- Blade diameter:12 inches
- Airflow:960 CFM
- Coverage area:Up to 1,400 sq ft
- Power:65 watts
- Speed settings:3
- Temperature control range:32–130°F
- Noise level:Up to 65 dB
- Installation:Wall mount, hardwired
Our verdict“Choose the iLiving for permanent greenhouse exhaust that can respond to temperature automatically, provided hardwiring and its noise level fit your setup.”
Tonree Grow Tent Clip Fans, 2-Pack, 5.5-Inch
The Tonree two-pack is the stronger fit when a grower wants adjustable circulation at two positions and needs a stated water-resistance rating. Its IPX5 rating and 360-degree adjustment offer more flexibility around humid tents than the VIVOSUN AeroWave D4, whose listing does not give a water-resistance rating. Each 5.5-inch fan has three speeds, an anti-slip clamp, and a 9-foot cord, helping reach poles or edges from 0.5 to 2 inches without a separate wall-mounted exhaust installation.
This remains a circulation set, not a substitute for the Amico or iLiving shutter fans when greenhouse air needs to be expelled. The USB Type-A power requirement means you must provide a suitable power source, and there is no battery for cordless placement. Its listed 40 dB noise level is also less quiet than the VIVOSUN’s stated 35 dBA. I’d pick Tonree for flexible, moisture-resistant airflow across a compact growing space, not for silent operation or whole-greenhouse ventilation.
Pros:- Two fans can direct airflow to separate parts of a tent.
- IPX5 rating suits damp growing environments.
- 360-degree adjustment and anti-slip clamps allow flexible positioning.
- Nine-foot cords provide reach to mounting points.
Cons:- Requires a USB Type-A 5V/1A power source; no battery is included.
- Circulates air but does not provide the exhaust function of the Amico or iLiving.
- Listed 40 dB noise level is higher than the VIVOSUN AeroWave D4’s stated 35 dBA.
Best for: Indoor growers who need two clamp-mounted circulation fans for humid tents and have USB Type-A power available at both positions.
Not ideal for: Buyers seeking exhaust ventilation, battery-powered placement, or the lowest stated noise; this set needs USB power and is listed at 40 dB.
- Quantity:2 fans
- Fan diameter:5.5 inches
- Airflow capacity:520 CFM
- Speed settings:3
- Motor speed:3700 RPM
- Noise level:40 dB
- Water resistance:IPX5
- Power source:USB Type-A, 5 volts
- Cord length:9 feet
Our verdict“Choose the Tonree pair for adjustable, water-resistant tent circulation when USB power is available, but use a shutter exhaust fan for greenhouse air removal.”
How We Picked
I compared these 15 greenhouse ventilation fans by how well their format and controls suit common greenhouse jobs: exhausting hot air, managing temperature or humidity, or improving circulation near plants. I also weighed stated airflow where provided, fan size, mounting approach, speed options, included controls, and the practical fit for a small tent versus a larger greenhouse. Features matter only when they help solve a real ventilation problem, so I treated thermostat control differently from oscillation or a clip mount rather than ranking every product on one feature list.
The order favors useful whole-space ventilation and adaptable controls first, then models with a more specialized strength or narrower fit. Wall-mounted shutter fans rank ahead for primary air exchange; compact clip fans rank as targeted circulation tools, not as replacements for exhaust. Since the supplied product details do not establish comparable noise, durability, or measured performance across the lineup, I avoid claiming those advantages and recommend checking the manufacturer’s specifications and installation requirements before choosing.
Factors to Consider When Choosing Greenhouse Ventilation Fans
Choosing a fan starts with the job your greenhouse needs it to do. These products fall into two different groups: exhaust fans move indoor air outside, while clip-on fans keep air moving within a growing area. The factors below help prevent a common mismatch: buying a fan with appealing controls or a large size that cannot properly serve the room or opening.
Separate Air Exchange From Air Circulation
An exhaust fan removes warm, humid air, but it needs a path for replacement air to enter the greenhouse. A clip-on fan moves existing air around leaves and can reduce stagnant pockets, yet it does not remove heat or moisture from the structure. Many setups benefit from both jobs, but a small tent may need circulation more than a wall opening and exhaust system. A frequent mistake is buying several circulation fans while leaving hot air trapped overhead. Decide which problem you are solving before comparing fan counts or controls.
Match Fan Capacity to the Greenhouse and Its Openings
Fan diameter alone does not tell you whether a model can ventilate your space; room volume, greenhouse layout, crop density, and airflow resistance all matter. Compare the manufacturer’s airflow information with your greenhouse dimensions, and account for screens, shutters, ducts, or other restrictions that can reduce effective flow. The listed 1,000 CFM on the Amico 10-inch is a stated specification, not a guarantee of the same result in every installation. Oversizing can create unwanted drafts or complicate mounting, while undersizing may leave heat and humidity lingering. Check the cutout and mounting dimensions before selecting a larger wall fan.
Choose Controls for the Way You Manage Conditions
A thermostat can switch or regulate ventilation around a temperature target, reducing the need for constant manual adjustment. Humidity control adds a different kind of automation, which may matter in a greenhouse where moisture buildup is a recurring concern. Remote controls and multiple speed settings offer convenience, but they do not replace a clear control plan or a correctly placed sensor. Consider where the sensor reads conditions and whether it can represent the area where plants actually grow. If you prefer simple manual operation, paying for more controls may add complexity without solving a problem you have.
Plan the Installation Before Buying
Wall-mounted shutter fans need a compatible opening, secure support, and a safe route for wiring; the largest fan is not useful if the wall cannot accommodate it. Clip-on fans avoid a wall cutout, but their clamps or hooks need a stable place to attach and enough clearance to aim airflow safely. Measure the mounting location, not just the fan housing, and check what installation hardware and electrical requirements the manufacturer specifies. Also plan how incoming air will enter when an exhaust fan runs. A poor intake path can limit airflow even when the fan itself is appropriately sized.
Account for Plant Placement and Airflow Pattern
Direct, constant airflow on delicate leaves can cause stress, so circulation fans are usually more helpful when aimed to create gentle movement across the growing area rather than at one plant. Oscillation can spread airflow across a wider zone, while a fixed clip fan gives more targeted direction. Greenhouse benches, hanging plants, and dense foliage can block or redirect air, making placement as important as fan selection. Avoid assuming one small fan will reach every corner of a long space. A simple layout plan can show whether you need one broad pattern, several local circulation points, or an exhaust-and-intake arrangement.
Pay for Features That Fit Your Routine
More speed settings, remote access, or environmental controls are worthwhile when they make regular adjustments easier or help maintain a stable growing environment. A premium control set is less compelling if you rarely change settings or already manage ventilation through another controller. For a beginner, a straightforward thermostat-equipped exhaust fan may be easier to use than a system with several control modes. For a small tent, a pair of clip fans may be a more relevant purchase than a large shutter fan, provided the tent has another way to exchange air. Compare the feature set with your actual routine rather than treating extra functions as automatic upgrades.
Frequently Asked Questions
Can a clip-on grow tent fan ventilate a greenhouse by itself?
No. A clip-on fan such as the VIVOSUN AeroWave or the dual-fan options moves air around the growing area, but it does not exhaust heat or humidity from the greenhouse. It can help reduce stagnant pockets and support more even air movement near plants. If indoor temperatures or moisture are building up, you need a way to exchange air with the outside, such as a suitable exhaust fan and an intake path. Use clip fans as circulation support, not as a substitute for ventilation.
Should I choose a 20-inch exhaust fan or a smaller model?
Choose based on the greenhouse’s ventilation demand and the wall opening you can safely provide, not diameter alone. The iLIVING and CAMMOO 20-inch options may suit buyers who need a larger wall-mounted format, while 10- and 12-inch models can fit smaller spaces or openings. Check airflow specifications, mounting dimensions, and any restrictions from screens or shutters before deciding. A fan that is too large for the opening or layout can be harder to install and control without delivering a better result.
Is thermostat control enough, or should I prioritize humidity control too?
Thermostat control addresses heat by responding to temperature, while humidity control can help when moisture is a separate, persistent concern. The CAMMOO 20-inch is the lineup’s standout option for temperature and humidity controls; several other exhaust models focus on thermostat or speed control. Think about the conditions that actually challenge your crops and whether you already monitor them with another device. If humidity is not a recurring issue, a simpler temperature-focused model may be easier to operate.
Do I need an intake vent when installing a shutter exhaust fan?
Yes, the greenhouse needs a route for replacement air to enter as the exhaust fan removes indoor air. Without enough intake area, airflow can be restricted and ventilation may not work as expected. Plan the intake location so incoming air can move through the space rather than short-circuiting directly to the exhaust. Screens and other barriers can also affect airflow, so include them when sizing and placing the system. Follow the fan maker’s installation guidance for the specific wall and opening.
Which type is easier for a first-time greenhouse grower to manage?
A wall-mounted exhaust fan with straightforward thermostat control can be a manageable starting point when heat buildup is the main issue; the iLIVING 16-inch is the roundup’s best all-around fit for that role. If the space is a small tent and air exchange is already handled, a clip-on fan offers simpler targeted circulation without cutting a wall opening. Neither format solves every ventilation need, so identify whether you need to remove air or move it around first. Beginners should also check wiring, mounting, and control instructions before installation.
Conclusion
For the best overall, I’d choose the iLIVING 16-inch shutter fan for its balance of exhaust format, thermostat, and variable speed control. The best value in practical features is the VEVOR 10-inch, which offers a smaller wall-mounted option with stated 820 CFM; confirm that its capacity suits your space. For a best premium feature set, the CAMMOO 20-inch is the clearest choice when temperature and humidity control both matter. I’d point beginners toward the iLIVING 16-inch for a straightforward primary exhaust role, while the Amico 10-inch is a strong fit for buyers who want remote operation and a stated 1,000 CFM. For compact, plant-level circulation, choose the VIVOSUN AeroWave E6 Gen2 or a two-pack clip fan, but pair it with suitable air exchange when heat or humidity needs to leave the greenhouse.
