G.A.S Enviro Controller - V2

To keep your climate bang on, your fan speed works with other bits of kit.

You might need to run fans quickly to cool, but also activate your humidifier. 

You can run your intake fans and extractor fans at different speeds. Both intake fans run at the same speed, both extractor fans run at the same speed.

You can have a different temperature and humidity for 'lights off' & 'lights on'.

That's 1,200W from each exit cable - 4 x 600W lights in total!

The unit's sealed to prevent any water ingress.

For a couple of minutes at set intervals, fans are ramped up to max speed. All the air in your grow room is quickly replaced. This keeps your CO₂ high and stops your humidity rising. This feature overrides all other functions. 

Overall, the whole unit runs at 3,000W, so:

• If you only use EC fans, the whole 3,000W can go on your 2 x exit cables
• If you use AC fans, you need to knock their wattage off the total unit's 3,000W.

e.g. if you run the total 2,200W for AC fans, you'd have 800W left to play with.

You can run no more than 2,200W on each exit cable. Don't go higher than 1,200W with grow lights, though because of their start up surge.
