hey everyone. i'm plannin on starting in aug so i got plenty of time. i just want to get it right the first time so i'm planning on going all organic with some subcool seeds. i want to veg them to about 2ft to get some big plants and i was thinking 3-4 total. i'm probably going with a 400w mh/hps system. my problem is i need to know how big i should build the grow room. i was thinking 3x3x6 or something. does this sound alright or too small? any tips or suggestions would be great. thanks
