Not breeding but I did a seed run last year on some autoflowering mini thunderfuck. I think I grew off about 30 of the little things early this year. 1 plant = 1 pipe bowl, LOL! Up until a couple of months ago I totally sucked at cloning. Finally I bought a clone machine and some Clonex and it worked for me. All the girls I have in my hydro unit is from clones I did not manage to kill. I tried Olivias, and RooTech but never got one to grow the first root. I think the main thing is having a good, big humidity dome and spraying them often. Cloning is the way to go for sure.
