Secret Jardin Monkey Circulation Fan - Pole-Mount Airflow That Won't Slip
Best for: tent growers who need a clip-on circulation fan that won't slide down or drop off a vertical pole.
Our thoughts
The Monkey Fan solves a genuinely annoying problem - keeping a clip fan actually clipped on. The pole-mount design pivots freely but grips properly, so it doesn't creep down the pole over a few weeks like cheaper clip-ons tend to. Straightforward circulation fan, no gimmicks.
The Secret Jardin Monkey Circulation Fan is a compact, pole-mounted air circulation fan designed to clip securely onto grow tent vertical poles without slipping or falling. Instead of a standard clamp that can loosen over time, it uses a non-slip mount that pivots freely, letting you adjust height and angle without worrying about it dropping onto your plants. This listing covers the two available power outputs: a 20W oscillating model and a 30W fixed model, both built around a brushless DC motor for quiet, long-running operation.
How it compares
The Monkey Fan sits in solid mid-ground in the clip-fan market.
- vs budget clip-on desk fans adapted for tent use: the pole-mount pivot clamp is specifically engineered not to slip down grow tent poles, unlike generic clip-ons
- vs premium smart circulation fans (AC Infinity CLOUDLINE, Spider Farmer): no app control or multi-speed digital dial, just 2 physical speeds, but costs considerably less for straightforward circulation duty
- vs floor-standing oscillating fans: mounts on the vertical pole, so it doesn't eat into tent floor space and airflow isn't blocked by the canopy at floor level
In plain terms: you're paying for a proven, simple design rather than smart-fan features you may not need.
Usage guidance
Installation
Clip the mount onto a vertical tent pole between 16mm and 30mm in diameter. Three fastener sizes are included so one should fit your pole - it takes about 30 seconds to secure.
Height adjustment
Slide it up or down the pole as needed - get it close to heat sources like ballasts or heaters, or position it to move air over problem areas where humidity or stagnant air builds up.
Angling and airflow
The pivot mount lets you tilt the fan up or down to direct air across the canopy, underneath it, or straight at a hot spot. The non-slip design means it stays where you put it.
Oscillating model (20W)
Switch oscillation on for wider passive coverage without repositioning, or leave it fixed for a tighter, directed airflow.
Fixed model (30W)
Points in one direction only - choose your angle once for stronger, sustained circulation in bigger tents.
Running the motor
Two speed settings on both models. Run on low for quiet operation during lights-on, and dial up to high for more aggressive circulation during lights-off or to handle humidity spikes.

Who this is for
- Growers running 2x2 to 4x4+ tents who need space-saving circulation without losing floor area
- Anyone who's had a cheap clip-on fan slip and drop onto their plants
- Budget-conscious setups where simple, reliable airflow matters more than smart features
- Growers wanting light oscillating coverage without paying for a full smart fan (20W model)
Our take
The Monkey Fan does what it's supposed to do - deliver quiet, reliable air circulation without drama, and without falling off the pole halfway through a grow. Both the 20W oscillating and 30W fixed models are solid, no-frills workhorses for the job.
If you need simple, space-saving circulation and don't need app control or a dozen speed settings, this is worth picking up. Does exactly what it should, day in, day out.
