Why do You Need Oscillating Fans in Your Grow Tent?
Both grow tents and grow rooms require fans for circulation, as well as separate fans for proper exhaust. It’s not enough to just get the air inside.
Without an exhaust fan, your circulation fan will be blowing out stale, hot, humid air that lacks the necessary carbon dioxide. In that environment, your crop will never reach its potential. So when you plan your grow tent fan setup, plan for proper air circulation and exhaust.
Why do you need oscillating fans in your grow tent?
Oscillating fans are the best solution for improving airflow. They’re better than not using a fan at all (naturally), but they also have some critical advantages over standing fans. You can adjust the location of the oscillating fan easily — from the top of the tent to the middle, to the bottom. Each site has a benefit to it.
Above the canopy, your oscillating fan helps dissipate heat from your grow lights and provides CO2 to tips and buds. Position your fan so it covers as much of your canopy as possible and rustles the leaves.
Fans below the canopy help keep air refreshed within and below the canopy — this helps control temperature and moisture and, as we said, this helps reduce the chance of pests that prefer higher humidity. It also helps dry out any moisture or water off the floor.
In the middle of the tent, your oscillating fan will help evenly disperse air through the canopy, balancing temperature and humidity, and rustling leaves and moving stems and branches so that your plants will become more resilient as they continue to grow. Oscillating fans are the only type of fan that is versatile enough to cover any part of the tent as necessary.

This VIVOSUN clip-on fan has 2 speeds (low: 1500 rpm; high: 2100 rpm), which can circulate air in the growing tent to improve ventilation and consistent temperature. The growth tent fan supports 80° horizontal swing and 120° vertical swing, which can guide the airflow to exactly where you need it. It is equipped with an easy-to-open clip (maximum 1.7 inches) suitable for poles of 16 to 22 mm; the thickened non-slip pad on the clip will not scratch the surface. This oscillating fan contains a 20W upgraded copper motor, which is small and powerful; the maximum noise output is only 40 dB, it will run super quietly and will not disturb you at all.
Things to Consider Before Buying the Right Grow Tent Fans
Now we know why it’s so important to have a grow tent fan, and how hard you’ll need it to work depending on the size of your tent and the accessories you use.
Speed Setting
The more control you have over your growing environment, the better. Therefore, we recommend purchasing a fan with adjustable speed settings, or (for most inline fans) buying it separately. This way, you can experiment with various settings to get the perfect airflow, humidity and temperature.
You also need to consider that the dials/buttons are easily accessible from where the fans are located. Some oscillating fan models even come with remote controls so you can operate them outside of your grow tent.
Clip-on fan head adjustment and movement
You need to be able to control the swing of the fan to ensure your grow space is well oversubscribed. Again, the more control you have, the better. Most fans will oscillate from left to right, while some advanced models will have a more complex figure-of-eight motion for better airflow.
You should also be able to tilt and adjust the fan head to get the air flow just right so your plant stems get a good daily workout.
Security Features
Your grow tent needs to provide a stable growing environment for your plants. But it also needs to be safe for your plants and anyone you share your living space with.
You can choose from ETL-certified and CETL-certified fans. That means it’s made with safer parts and a higher quality build.
Conclusion
Ventilation is crucial in grow tents as it maintains optimal humidity and temperature while replenishing CO2 levels. While there are various ways to ventilate your grow tent, keep the following in mind:
The size of your grow tent determines the number of fans you will need. The bigger the tent, the more fans.
Seal the fan properly to avoid any leaks.
Make sure you buy a carbon filter that can handle the CFM (cubic feet per minute) of your exhaust fan.
