Growing plants indoors in these hot summer months?
Remember, environment is everything, and grow room fans are an essential part of your set up.
We highly recommend that you keep a few fans running in your grow room to get the most out of your plants and to keep your plants as productive as possible, whatever the weather, but especially during the really hot / heatwave months.
Fans are an often-overlooked grow room workhorse and are essential to help deliver carbon dioxide to your plant’s leaves. They can also help prevent diseases and reduce heat spots in your grow room.
In this blog we are going to take a look at the different types of fans we sell, so that you can keep your grow room cool and breezy all year round, providing the ideal environment for your plants to thrive!
Air Movement Fans
Air movement fans (also referred to as air circulation fans) help growers achieve optimal climate conditions in their grow room by circulating air around the room.
They are a great way to moderate the temperature of the room, helping to keep it cool and create a constantly moving atmosphere.
Air movement fans have a multitude of advantages when it comes to the aeration of your plants when growing indoors… keeping your grow room cool and helping the air in the room move around freely… and they also help prevent hot spots and circulate C02.
Pro Tip: Don’t blast air directly onto your plants too powerfully, instead opt for a nice gentle consistent breeze. This will also help strengthen plants and help prevent mold issues.

EC Fans
Efficient and powerful EC Fans are a must-have for your grow room. Electronically Commutated (EC) fans combine the benefits of both AC and DC fans, essentially giving you a fan with a brushless DC motor. This the next next
EC Fans give you the control that an AC fan gives you over the fan rotor by using a printed circuit board, and they also have the advantage of built-in variable speed control thanks to the DC motor.
The EC fan is powered by an AC electrical supply, but the onboard electronics convert the power to DC before reaching the motor. The secondary magnetic field generated by the permanent magnets makes EC fan motors considerably more efficient than AC induction motors.
