My grow room is way too hot, its at a constant 100 with the light on. I am running a 1000w hps with a cool tube well just look at the picture, but behind the light is a 400cfm fan and the tube at the top is a muffler I made (which cost like $20 and is just as good as the phresh muffler, ask for instructions). I have a high velocity fan pulling air in so its a passive air flow. I live in a very hot climate so thats a downside and I can run a seperate a/c for it, what should I do? couple ideas i had was to just get rid of the 1000w and downgrade to a 600 or even 400 but I want to get the most possible yield. Can my plants grow good in 100 degrees as long as I keep the water cool (DWC/aeroponics)? Suggestions...
If AC is possible you will need at least a 6000btu than ditch the cool tube and just get a wing. The tube holds heat and that's bad with AC.
If you keep you water cool say 60 to 65 that's good, RDWC or DWC is the way to go, insulate the buckets and the tops also. Watch out for condensation if you don't use AC. The cooler the water the more desolved oxygen it holds to a point. I run at 61 all the time but kick it down to 58 for the last 2 weeks this can bring colors out in some plants and stimulates more resin production.
