I'm no expert...
From what I've seen it varies on the grower. One guy can get a pound of it from a couple plants, and the next will only get a few grams. Looks like my two will give me about 1/4-1/2 lb unless they swell up in the next week. They're both loaded with cloudy trichs, with more amber popping up here and there, So I'm hoping they'll be done by Monday.
Most of what I knows about high yielders comes from here in LS, by the way.
