IIRC I took 3 females at 9.5 weeks from seed and they yielded around 2.5 oz dry from all 3 but I had to move them from my veg tent into my 12/12 for the last 3 - 4 weeks so it certainly would have effected the yield. The quality and smell more than makes up for the small yield though. Dry them slowly and give a decent cure and you won’t be disappointed.
If you scroll down from that post there are a few more posts from me about them
