ya i agree with the whole 99 plants deal... i say have one room with 9 mothers, one room with 40 veggers under like 10 1k mh and another room with 10k hps and just flower some huuuge effin trees so you can stay within the i guess limits so to speak and still harvest mad medicine.. just hang 1k bulbs between all the trees for a semi vertical setup so they dont stretch out too much cuz if its an old auto bay im sure height isnt an issue... doin this you should be able to get 10-15 lbs easy.. more when you perfect it and depending on how big they get
