Climate control
by Cyclone
The Cyclone Oscillating Clip Fan is a 20W clip-on fan that mounts directly to your grow tent poles, delivering a gentle 180-degree oscillating breeze across your canopy. It weighs next to nothing, clips on in seconds, and runs quietly enough that you'll forget it's there — until you notice how evenly your plants are growing. If you've ever dealt with hot spots, damp corners, or limp stems, this is the fix.

Complete your climate setup. Pair the Cyclone clip fan with a carbon filter and inline extraction fan for full air management — the clip fan handles circulation inside the tent while the extractor pulls stale, humid air out. If you're running a small tent, a clip-on hygrometer lets you monitor exactly what the fan is doing for your temperature and humidity levels.
An oscillating clip-on fan solves problems you might not even realise you have yet. Here's what actually happens inside a sealed tent without air movement: warm air rises and pools near your light, cool air sinks to the bottom, and moisture from transpiration hangs around your canopy like a wet blanket. The result? Uneven growth, weak stems, and the perfect conditions for mould and mildew to set in.
We've seen growers spend hundreds on lights and nutrients, then lose half a crop to bud rot because they skipped a fan that costs less than a round of drinks. The Cyclone's 180-degree sweep keeps air moving across the entire canopy rather than blasting one spot. That constant, gentle breeze does two things: it disrupts the humid microclimate around your leaves (where fungal spores love to settle), and it physically stresses the stems just enough to encourage them to thicken up. Growers call it "wind training" — the plant responds to movement by building stronger cell walls, much like how trees on windy hillsides grow stockier trunks.
The honest limitation? At 20W with a 15cm blade, this fan is built for small to medium tents — think 60x60 up to about 120x120. If you're running a 240x120 or larger, you'll want two of these on opposite poles, or step up to a floor-standing oscillating fan. For anything up to a 120x120 though, one Cyclone mounted at canopy height does the job properly.
The clip itself is the first thing you notice — it's a proper spring-loaded jaw, not one of those flimsy plastic pinchers that slowly slides down your tent pole overnight. You can feel the tension when you squeeze it open. It grips round poles (16–25mm diameter) without any wobble, and the rubber padding on the jaws means it won't scratch or dent your frame.
The two-colour design (black housing, white blades) looks cleaner than most grow room fans, which tend to be all-white and industrial. Not that aesthetics matter much inside a tent, but if your setup is in a living space or bedroom, it doesn't scream "grow room" quite as loudly. The head tilts and locks into position before you switch on the oscillation, so you can aim the sweep exactly where you need it — across the top of your canopy, or angled down towards the pots if you're battling surface moisture.
Noise-wise, it's genuinely quiet. Not silent — you'll hear a soft hum and the faintest click as the oscillation mechanism reverses direction — but it won't keep you awake if the tent is in your bedroom. Compared to a clip fan from a hardware shop, the difference is noticeable. Those cheap desk fans rattle after a week; the Cyclone's motor runs smooth.
