I'm in the process of building my ubergrowop, I'll post pictures when it's ready and I'm pretty sure its gonna turn a few heads.. in a good way I hope.. but I was wondering how much dry weight do you average per plant?

also how much dry weight could you get from a 50-60cm (20"-24") big bud plant with 1000w hps in optimum conditions?? 20-24" is full size for big bud right??

thx hope someone can lend a helping hand
