Hey sorry it took me so long. i estimated two lbs because on my last batch i got easy ounce and 1/2 per plant. That was with 8 plants and now i have 29 so i think i should get about 2lb's. Its really just an estimate ill let ya know how it turns out.
I water by hand with a pump that goes to a reservoir. In the bottom of the black trays is a hole that drains all the water into buckets.
All i have done the whole time is used Ph'd water too so im pretty excited to see it do so well. And believe me those are some dense nugs on there.
