CO2 Double D Burner 8 outlet

Uses LPG to create CO2

If you are using a digital controller it will turn on and do very short burns. Will not generally make the room hot unless you have a lot of leakage.

Ideally we would design the room with air conditioning at around 30 degrees +  exhaust and inlet fans turned off during the light cycle + all lights inside our air cooled reflectors so no heat enters the room (or use LED's) and the air conditioner doesn't work hard at all.

Ideal CO2 levels are 1200-1500ppm where growth and flowering accelerates madly....
