Sorry to butt in. I want to know the answer to this aswell for me. Lol 30 litre air pot, G13 Purple Haze 1 plant scrog/top/fim +supercrop grow. Will be using bio bizz light mix, bio grow and bio bloom. drobe, area would be 90cm wide, 5o cm deep and 1.6m high. Would 2 Helios pro 2's + a 250 lumatek dimmable/super lumens grow a monster?
Again, sorry for butting in, but you started a very good thread/post.
