I havent actually used it but im about to. I picked one up as a gift and i been gathering the rest of the equipment i will need. Which is a ton of stuff really. Kinda a pain in the ass when you have tight budget. But i have heard everything from a pound total to 3.3 z per site. Like i said tho just heard i havent done it yet. But im thinking 2 per site isnt out of teach when i was getting .75 z ebb and flow with 64 plants on a 4x4 table harvest every 30 days a 4x4 with 64 3/4 oz colas. Lollie pop the hell out of them the first 2 to 3 weeks of flower. I mean it when i say lollie pop. Leave only 2 leaves and a new shoot. I was shooting for a zip but only got .75. 4x8 with 3800 watts.
Somoene said they got 5oz per sf ebb and flow lollie popping. Some wont believe it because they cant achieve it. I know how big things can get when things arr going good. I think its possible.
