Oscillating Monkey Fan – Secret Jardin | 20W Clip Fan for Grow Tents

The Oscillating Monkey Fan by Secret Jardin is the definitive tool to ensure perfect air circulation in your indoor grow, designed specifically to grip tent poles without slipping and simulate a natural breeze that strengthens your plants.

Is your grow tent suffering from stagnant air?

We know the drill. You open your indoor setup and find that one corner is humid while another is dry, or worse, you find your clip fan has slid down the pole, crushing a branch or aiming at the floor. Relying on static fans or cheap clips often results in poor air distribution, creating dangerous micro-climates where fungi like powdery mildew love to party, while your plants grow weak stems due to a lack of proper wind resistance.

It is incredibly frustrating to invest time and money in premium nutrients and lights, only to have your harvest threatened by something as basic as airflow. Watching your plants struggle against heat pockets or finding mold just days before harvest is a nightmare every grower wants to avoid. You shouldn't have to use duct tape or zip ties just to keep a fan in place.

The Oscillating Monkey Fan changes this scenario completely. Thanks to its unique coupling system, it locks onto the structure of your tent and stays exactly where you put it. By oscillating, it mimics the chaotic nature of outdoor wind, eliminating hot spots and forcing your plants to develop thicker, sturdier stems to support heavier buds.

What this product includes exactly

This isn't just a fan; it's a piece of engineering designed by growers for growers. The Secret Jardin Monkey Fan is built to last and perform in the humid conditions of an indoor garden.

• Monkey Clip System: Compatible with tubes from 16mm to 21mm diameter.
• 100% Copper Motor: Ensures durability and continuous operation without overheating.
• Oscillating Head: Provides a 90-degree sweep to cover more area (up to 3m²).
• Two Speeds: Customize the airflow intensity based on your plants' growth stage.
• Metal Grid: Safety first, protecting both your fingers and your leaves.
• Cable length: 240 cm for easy reach to power strips.

How your routine changes from now on

Once you install this fan, you can say goodbye to the daily "fan check." You will notice that the temperature and humidity levels inside your Grow tents become much more uniform. No more hot pockets burning the tips of your leaves near the light, and no more damp corners inviting pests.

Your plants will respond almost immediately. The intermittent breeze created by the oscillation stresses the stems just enough to trigger a hormonal response, making them thicken up. This means that when flowering comes, your ladies will be strong enough to hold up heavy colas without needing as much support.

Advantages and benefits you’ll notice from day one

• Zero Slippage: Because of the locking clip, the fan stays at the exact height you set, protecting your canopy from accidental falls.
• Mold Prevention: The oscillating motion eliminates dead air zones, drastically reducing the risk of Botrytis and powdery mildew.
• Space Saving: It attaches to the poles, leaving the floor free for more pots or easy cleaning.
• Extended Durability: The copper motor is built to run 24/7, meaning you won't be buying a replacement halfway through a cycle.
• Versatility: Fits almost any standard tent on the market (16mm to 21mm poles).
• Easy Setup: No tools required; just clip, click, and plug in.

Tips to combine it with other Pevgrow products

To achieve the perfect environment, airflow is just one part of the equation. While the Monkey Fan moves the air around, you need to ensure you are exchanging that air to keep CO2 levels high and heat low.

• Extraction: Pair this fan with a quality extractor from our Air fans section to ensure old air is removed while the Monkey Fan circulates the fresh air.
• Humidity Control: If you are in the vegetative stage, place a humidifier near the intake, and let the Monkey Fan disperse the mist evenly across the canopy.
• Support: For those massive yields, combine the stem-strengthening wind of this fan with a SCROG net or stakes.

Frequently Asked Questions

Will this fit my grow tent?

Most likely, yes. The Oscillating Monkey Fan is designed to fit poles with a diameter of 16mm to 21mm, which covers the vast majority of grow tents on the market, including Secret Jardin, Mammoth, and generic brands.

Is it loud?

It is designed to be quiet enough for home use. While no fan is silent, the copper motor and quality build minimize vibration and noise, so it won't disturb your peace.

Can I use it for seedlings?

Yes, but be careful. Use the lowest speed setting and ensure the fan isn't blowing directly on very young plants to avoid windburn. The oscillation helps mitigate this risk by not keeping the air focused on one spot.

How large of an area does it cover?

One Oscillating Monkey Fan is effective for an area up to 3m². For a standard 1.2m x 1.2m tent, one is usually sufficient, though two (one at canopy level, one below) provide the ultimate airflow coverage.

Personal Experience of Pevgrow’s CEO (Alan)

I've lost count of how many cheap clip fans I've thrown away over the years. You know the type—the ones that start rattling after a week or slowly slide down the pole until they're blowing into the side of a pot. When I switched to the Secret Jardin Monkey Fan, the difference was night and day. The way it locks onto the pole gives me total peace of mind; I know it's not going to fall on my prize genetics while I'm sleeping.

My pro tip: Don't underestimate the oscillation. Static fans can dry out leaves if they point at the same spot for too long. This oscillating feature mimics nature much better. I usually set up two in my larger tents—one blowing just over the canopy and one circulating air beneath the foliage to prevent humidity buildup in the dense lower parts. It's a small investment that saves a lot of headaches.
