Just thought of another problem! I can't hook up the AC to the timer cause you have to press a couple of buttons to get it running. And if I leave the AC on I can't cordinate it with it co2 due to it just sucking it right out! WTF? I think I should have bought a split AC and just made it a closed loop system, but that's more money which will take more time to scratch up. Would running the canopy temps in the low 90's really be a problem? Any thoughs or advise would be appriciated.
