I was just talking to a friend earlier tonight about this. He said that he grew his males up to good size and cut them down, before they busted open, clipped the sacs off then hung the plant upside down to cure. He said it was not great, But it wasn't bad either. Said it was a decent high. So I think I'll try it for any males I have out of this grow.
I also read somewhere it varies alot at how much THC they have.
