hello, just thought i'd throw my 2 abes your way, heres a pic of my cab, which is going to be a scrog cab in the future, but since i'm only half done with it, i'm growing straight from seed untrained, btw, I drew inspriration for my cab from justaseeds. The height of my cab for the flowering "side" is 39 inches and the height for the future vegging side is 24 inches. my previous grow box was 29 inches and it turned out to be more than adequate for my first grow. Read up as much as you can from these forums, theres alot of good info in these here threads
