Well, these plants are still alive so couldn't tell ya yet. Never done this kind of growing before. Guessing an average of 20grams. Some look like they'll pull off a little more than an oz. With the right strain, you should be able to get an oz. Even 12/12 from seed.
Of course, experience and how well you treat your girls will determine this. Also, nutes, lights, so many other factors. Just cuz I get an oz, doesn't mean you will. Or that someone can't do better. My advice, grow it and find out.
How about some opinions on cutting the girl in the last set of pics. The "Big Girl" I just gave a nute watering today. But next water I was planning on starting her flush for 10 days, then chop chop. I feel I may be rushing it. Her hairs are about 20% red now. With the trichs mostly clear, with some cloudy ones. I don't want her to miss out on fattening up those love handles. Whatchathinkboutit?
