Ive been a reader/ searcher for years, this might be my first post. Im a med patient also. long story short i have moved, and wife kicked me and my grow to the garage. I live in northern U.S. and summer temps get mid to upper 80's with very high humidity. i am ordering the dr 150 grow tent tom for the garage with a 1000w hps, with a 8" coolable hood. the garage gets very hot and humid and i will have to run an a/c but don't wanna spend alot, whats my best a/c option. can i use a window a/c? and have the hot air exhaust into the closed garage? or do i need a portable ac? thanks for any help, i really need it.
