Not a problem. The CO2 buckets can work, but even better are CO2 generators or CO2 tanks. With the generator and the tank you would use an atmospheric controller that would monitor the PPM in your room and dose the CO2 accordingly when levels get too low or too high and a good controller will shut off when lights go out. For the tank you will also need a CO2 distributor that has all of the tubing and proper voulbs and you plug this into your controller. It can make a huge difference, up to 30% more yield.

BlueBear Reviewed by BlueBear on . Question about sealed room with no outside air? OK guys, please help me with this. I have a 6X15 room and 4 1k lights are going to be installed. I will be usin a fan from outside and cooling the lights through a 6" duct to the outside. I will use a can 66 filter, dehumid and fans inside the room. My questions are: Will the heat from the lights still be too much for that size room w/o an a/c? If it is sealed do you have to have fresh air or can it keep using air from the room through the can filter? If it does stay cool enough Rating: 5
