it is possible for 3lbs but difficult.2lbs is not unreasonable dry. but as fuzzy said its down to many things and a new grower would struggle to get that. scrogging of 1 plant vegged and trained properly can do it, likewise so could several. the bottom line is, if u train ur plants correctly and follow a good nute programe u can get very good yields, more so in hydro. off 2 600w i can easily achieve 50-60oz of 10 plants dwc.
I was thinking if I could get 2oz per plant 8 plants all in one large bucket. U think I could pull a pound? The thing is.... how tall should I veg to get two ounces per plant without the Scog or dog. I don't know how to do neither so I figure ill grow str8 up. Dwc.
its not about how tall, tall can actually hinder the amount of bud u get. u want bushy with an even canopy, 10-12 heads. just keep topping and keep plant no more than 2 foot in veg. i only veg to around 1foot indoors but have very bushy plants that yield high.
also the m2 could be 1 plant trained well or many, but the seed companies in holland go of 9 plants per m2. its not the number of plants that matters, its how much light u have and how u train ur plants.
