I have 16 plants and they are running 12-22inches tall. A couple are getting bushy. There is a possibility I may have to pull a couple plants if some turn out to be hermies. I planted some seeds to see what would happen and they are growing really well. The one in the front is the big one. It keeps growing like crazy. 2 weeks back it was less than a foot tall.
Post this in the absolute beginners sub forum over at cultivation. You'll get a lot better help there.
