males...Usable or toss em?

I started with 16 seeds now have 3 guarenteed girls.... there are 4 others i am waiting a few more days to see but pretty sure the rest are male. Can I do anything with these boys (ie hash or some other thc smokable)? Or are they just food for the bon fire?

thanks much

toss it... I dried a male plant in the house to make cannabutter (what a waste of time) and the pollen sacks ended up bursting and the pollen drifted and got sucked into my flower room. Yup, pollinated my bitches and got seeds in my bud. Worked out well as I have taken a liking to the strain I grew and the mess of seeds I got will be put to good use.

Keep one isolated, take some pollen from it and very carefully pollenate one of the gurlz. Get yourself some serious seed stash. You can safely do one or two branches of a female and leave the rest sensimilla.
