To Separate or Not?

ok so if the grow tent i am growing will be roughly 7 feet tall could i put in a platform about three feet high and separate the tent into two sections with the top having 12/12 600w hps for flowering and the bottom a t-5 for vegging? id have to seal off the light from going up through to the flowering part but i think this would maximize the space. im doing a scrog method so i can control how tall the plants get but i think with an air cooled hps i can use about four feet and be fine. what do you guys think?
perhaps even use just three vertical feet to grow scrog? would that be adequate height? then maybe split the tent into two flowering platforms with two hps lights. i dont know. i dont know the best way to utilize this space. i also have ano0ther area to veg my plants in that is about three feet tall and four to five feet wide, two feet deep. what do you guys think?

try it and find out, pretty easy to control the height of plants.

yeah. im going to try some shit out. i havent figured it out yet but it will be good. there is just so much to think about when growing stealth-like and trying to maintain a decent yield of good bud. thank God for RIU
