Thanks that was a ton of help. You are right I am half as$ing this project, I tried to forget about temp and that won't work. I haven't started Aeroponics yet I have seeds planned for that but I don't want to screw it up. So I am in dirt for now. Will switch to 18/6 today when A/C is in, just needed to keep it 24/7 until I got the temp right. Tomorrow during afternoon it will be lights out, yes I have good light control at least..

I will have intake/outtake into the attic and a backup a/c unit. The intake will be by a vent hole. The temp control on this little 12000BTU a/c I am installing is great, I need to find a smaller A/C that has great temp control. I think here in Cali in the summer I am just going to have to go lights out or just burn CFL to do a 3 month VEG. lol I will post up my results when I am done with the vent system.

I am stopping and buying a vented hood today. What do you think about that tube HOOD? The one I seen at our local hydro shop said not for BT-56 socket, gotta see if that is what I have.
