yea...keep your plants small. grow sog. get 2 3x3 flood tables and you should be able to fit 15 pots per table pretty easy. if you are buying rooted clones then go straigt to flower to keep them small. 1-2 gallon pots should be perfect. try sunshine #4 mix with worm castings. use house and garden 2 part soil nute. get a good pH/ppm meter. if you get the flood tables then tilt them to 1 side slightly. install a drain fitting on 1 end. that way when you water you can catch all the runoff in a bucket. also helps to clean the tray...just use a hose or a bucket of water and rinse the tray out. i'd use 1 400w per tray. try the new hortilux super hps bulbs. they are great. more blue in the spectrum. you could also do a perpetual grow. that way you get a harvest every month instead of every 2. just start 15 in 1 tray and 30 days later start another 15 in the other tray. just some suggestions. good luck bud.
