basement nirvana
Member
I am dedicating a 10' x 12' room in the basement for my flowering room and was wondering how I could go about using co2 while still having a negative air pressure room. I would think having a fan venting to the outside I would loose all my co2 quick like. Then if I had a carbon scrubber recirculating air in the room I would still have the smell push out of the door whenever I opened the door. One option I thought of is having a switch outside the door to turn on the outside vent before I walk in the room then off again. Anyone have any other suggestions? I want to utilize co2 if it is able to increase my yields by 20% or more but still don't want any smell detectable in my house.... thanks for any help on this setup dilemma!
