Wtf is a book? This here is interwebz knowledge at its finest, aka "bro science" Makes sense on the net placement though.
I agree on the colored co2, it would be a nice tool. Im assuming if the air is lighter, then the updraft wouldnt lift the heavier co2? Just seemed to make sense that if the co2 is heavier then the fan would blow it from below the canopy and the canopy fans would blow it down slightly so it would almost be like a little recirculation system. How's that for some bro science? Total speculation on my part :cry:
I honestly have no clue thats why i brought it up. You already have the tek in place so i figured i would ask. My exhaust is on ceiling and my intake is low so i figured that would pull the co2 upward without a fan down low. Shout out to all the broskies!!
