4th grow, new closet grow room set up... need some input

my grow cab in my closet is 5ft 5inch tall, 2ft 11 inch wide and 1ft 10inch deep. my lighting will be 400 watt mh/hps, i have ducting that is hung just below the light reflector and will vent out of the cab and up into the attic via a 4inch 8o CFM inline fan. I will prob go with another scrog as i have had some nice harvest with them in the past but using cfl in much less space. iam only using bio-grow, bio-bloom, molasses and diamond black but iam looking to add something to boost my weight and quality of flowers and will need some advise on that as well. I will prob go with a SCROG, def using foxfarm OF soil in 5 gal buckets. I need some feedback on my set up before i start set'n everything up, plan is to get at least 2 clones going end of september!!! This set-up gonna be worth a dam??

thats def not a bad idea at all. i have a 200 watt hydrofarm cfl around here somewhere i can throw in there and just change out lights when its time to flip. I know the heat is going to be my biggest problem so i may just have to see how that 80 cfm fan works.. i think for like 9 bucks more i can get a 150 or somethin.. i just dont want to be fighting heat the entire time and def dont have the extra money for a cooltube haha.
