I have always used commercial grade air pumps for my DWC. They generate a shitload of heat and noise, so I like to keep them outside of my room. Now that I have sealed everything off and am introducing co2, do I have to bite the bullet and put the damn thing in my grow room? I feel like blasting 110 liters of outside air per minute into my buckets could be forcing a fair amount of co2 enriched air out of the room. Is this an accurate hypothesis or am I just over analyzing? Perhaps this is why I see people running co2 using the little sissy whisper air pumps all the time? Sent from my iPad using Grasscity Forum
