Best Clip Fan for a Grow Tent

An inline fan and carbon filter pull air out of a grow tent. They don’t do much to stir the air inside it. A clip fan clamps to a tent pole and keeps air moving across and under the canopy, so warm or humid pockets don’t settle around the leaves and stems get a gentle breeze.

This guide compares three 6-inch clip fans from their published specifications: two oscillating EC-motor fans built for grow tents, and a basic two-speed fan. We did not test them ourselves, and we found no independent airflow or noise measurements for these models.

What to compare

• Airflow (CFM). All three are 6-inch fans in the 300 CFM range. In a tent the controls matter more than the last few CFM.
• Oscillation. An oscillating fan covers more of the tent from one clamp. Range settings let you avoid blasting one plant.
• Motor and power. EC motors offer many speed steps at low power. The two EC fans here are rated at 11 and 12 W.
• Humidity rating. A tent is warm and humid. An IP54 rating means the fan is protected against dust and splashing water.
• Clamp and controller. Check the clamp fits your poles, and whether the fan joins your existing controller.

AC Infinity CLOUDRAY S6

AC Infinity lists 325 CFM maximum airflow at 31 dBA, 25 Pa static pressure, 11 W at 100–240 V, a brushless EC motor with carbon steel gears and dual ball bearings rated for 67,000 hours, IP54 protection and ETL safety certification. It offers 10 speeds, 10 dynamic wind modes that vary airflow to simulate outdoor wind, and 10 oscillation ranges across a 90° rotation, with a 55° tilt and horizontal or vertical mounting. Its operating range is 32 to 140 °F and 35 to 85% RH.

It plugs into AC Infinity’s UIS controllers, which add app control, climate triggers and timers. If your inline fan is a CLOUDLINE, one controller can run both.

Vivosun AeroWave E6 Gen2

Vivosun lists 320 CFM at 33 dBA and 12 W at 100–240 V, a dual ball bearing EC motor, IP54 protection, 5-level auto oscillation across 90°, an 80° vertical adjustment range and a built-in timer. It has 10 speed levels with the app (5 without) and normal and natural wind modes. Vivosun says it retracts automatically to avoid motor jams when the oscillation hits an obstacle, and its clamp fits round or square poles from 16 to 22 mm. App control needs a Vivosun GrowHub E42, E42A or E25 controller. Vivosun lists 2-year after-sale service.

It is the match for a tent already run by Vivosun’s GrowHub; see Vivosun vs AC Infinity for how the two ecosystems compare.

Hurricane Classic 6” Clip Fan

Hurricane’s spec sheet lists 306 CFM and 2,350 RPM on high, two speeds, adjustable tilt, a strong clamp, a 5 ft power cord, and a draw of 0.15 A and 14 W at 120 V. Hurricane’s product page adds that it is UL listed and has a metal grill and steel neck. It does not oscillate and has no controller input.

It is the budget way to add circulation. In a small tent, one fixed fan aimed across the canopy, or two aimed in opposite directions, does the basic job.

Placement tips

• Across the canopy, not straight down. Aim for leaves that move gently, not leaves pinned flat.
• Under the canopy too. In a tall tent, a second fan low down moves air under the leaves.
• Away from the sensor. Keep the fan’s direct stream off your thermometer hygrometer so it reads the tent, not the breeze.
• Leave the exhaust to the inline fan. A clip fan does not replace exhaust or a carbon filter; LONGWELL’s calculator sizes the inline fan and suggests how many clip fans to add.

How these picks were made

We compared two grow-tent oscillating clip fans and one basic clip fan on published airflow, oscillation, power, noise, protection rating and controller support. We did not test these fans ourselves; see how we research.
