ok people, i am just throwing this question out there because i am getting reading a lot of conflicting things on here. which is better to do when running c02, to push the air or to pull it? ive been told that pushing is better because it causes less stress on the fan since it isnt pulling the hot ass air through, and also the fact that it creates negative pressure(i believe im right here) which in turn wont suck that c02 through the lights and what not. and then other people are telling me that pulling is better. so can as many people who care or even better if you have had experience doing both and have actual experience and know which one works better i would be much appreciated. thank you very much for any input people.
