Males!

My three most promising plants are deffinatly males. They are the biggest of the 5 I started sexing and I've been reading about making hash or cannabutter with the males. Or is that only if I had like 10+ males? Plus, should I let them mature a little more before trying such a thing? Or do they have about as much THC as their going to get? Finally, which is the better way to go with just males hash or butter?
I don't supose I could jedi mind trick them into becoming female or hermies
Just throwing away 2-3ft pants seems like a crime.
