What is a Fan Controller?

An extraction system is a very important part of an indoor grow setup. It removes stale, CO2 depleted, damp air, and removes heat too. The problem is that in colder months, an extraction system running at full speed can remove too much heat leaving your plants growing in sub-optimal temperatures. A fan controller allows the grower to balance the extraction rate with the temperature in the grow area, letting you maintain optimal conditions. This means that your plants will enjoy ideal grow temperatures all the time in your grow room which will lead to faster growth and bigger yields.

When you pair this up with fan controllers, you get full precision over your grow room whilst
