I'm debating whether I should move to hydroponics in a few months. My concern is wasted vertical space. My tent is a Grow Lab GL80L with about 6' 7" vertical Height. Right now My 5-gal soil pots are about 9.5" tall and with my Lights I get about 5' of grow space. If I were to move on to a hydroponics setup with a table and flood tray it would be 14" high, and with the pots maybe approach 20" high. I would lose almost of a foot of vertical grow space. Do you guys think this is significant? Would a hydroponics system's productivity counter this loss of grow space?
