Thanks, Well what I planned on doing was germinating 8-9 seeds in hopes that at least 7-8 germinate ok, then plan on at least half being male so that brings me down to about 3-4 then if its 4 pick out the best 3..

I think it works out to about 1 square meter per plant so that should be fine, and from the top of the trash can to the end of the exhaust it leaves me with about 3 and half feet of vertical grow room... I think that might be enough buuut I might try to get a few more inches of it when I build the base for it to sit on for the intake then cut holes for the final buckets to rest in... and yeah im using soil... Figure I should at least get a few soil grows in before I even start to think about hydro
