Ive been growin for a while, but never used co2 enrichment. I have a great intake/exhaust, so co2 is at 3-400ppm, approx. I know i would have to make sure the exhaust is off when co2 is on, but how about the intake?:hmmm: Would this be better/higher c02 levels? Anyone with exp help me out. :thankyou:
 
Presumably if you turned you exhaust off and left your intake on you would end up pushing your super high concentration out through any cracks and replace it with fresh air. but i could be crazy its been known to happen
 
makes sense. Ive sealed the cracks, walls and floors. so, in either case it would be wise to let the ventilation be off while the co2 is on? good insight, thanks!:bong:
