AVERAGE in my expirence is 1-2oz on a aeroponic system.the longer you let them veg(18-24lights)
the more yield.you MUST have good light coverage.good luck!!
I have done tables and ebb and flow,1 lbs every two weeks with only 12 plants (the legal limit)is not going to happen.I'm not bashing tables but this guy is a patient and he needs the best yield with limited plant count.
O.K. first do you know that they are even female plants?It sounds like they could be males.do you know?after that all I can say is if it's two feet tall and your running out of space you need to put it in bud now!!Sativa's double or triple in size in bud.Keep that in mind.Good luck
Once a plant go into budding it's very hard to take clones.It can be done but not smart.
The plant has to revert to veg state.This can take up to a month.Thats if it roots at all.
So if you can take clones off another plant do it.Otherwise I would take the clones and put them in a areoponic...
