ive got a chem d, some super snow lotus and some bugman c99f2s boys, how do you choose which ones to keep around dtog?
They need to stink on a stem rub, have great structure(like a nice female plant does) , and barely show sex in veg. That's how I've been deciding which males to keep. I always clone them before using to make seeds or flipping for pollen. That way if they make killer hybrids with plants I already I have grown a bit. I know they are worth keeping around to keep making seeds with.
There's nothing special in what I do. I just pick the plants I like, and cross the varieties I want to combine to see what they turn out like. I read something by one of the more famous breeders, I think it was Nevil. "Find a nice male and cross him to all your favorite females. Grow those seeds and figure out which variety the male mixed best with, or you like the most. Then continue the work from there". That's not an exact quote, but it was something to that effect, and it stuck in my head.
