What size do I need?

The dimensions of your grow room is the most important thing to determine the size of your exhaust fan.
We don't go too much into detail here but it's better to use an exhaust with more power than less because a heat build-up might damage your plants.

How to measure the volume of your grow room:

1. Dimensions
Height x Width x Depth of the room (e.g. 2.5m x 3 m x 2.5m=18.75m²)
2. Allowance for the activated carbon filter
Add approx. 35% to the room volume since the carbon filter reduces the power (18.75m² x 0.35=6,56)
3. Allowance for the duct hose
Per meter duct hose add approx. 1m² -» in our kit 2 meters - 2 x 1= 2 m²
4. Determine the exhaust volume
In a room we need an air exchange of minimum 12 x room volume per hour. In grow cabinets approx. 30 x 12x(18.75 + 2 + 6,56) = 327 m³
