iGS-221 CO2/RH/Temp Smart Controller

One simple controller to manage ALL of your indoor garden's climate parameters!

The iGS-221 can operate the intake and exhaust fans cyclically to replenish the garden's atmosphere in oxygen as it is needed for the plants and for safe CO₂ combustion generator operation.

When a CO₂ combustion generator (propane or natural gas) is used to raise the CO₂ level, ventilation for at least 2 to 5 minutes is mandatory to replenish the oxygen supply required by the generator's combustion. Insufficient oxygen supply in the garden's atmosphere allows accumulation of carbon monoxide, which is toxic to humans, and ethylene, which is toxic to plants.
