Those pics do look male to me. They are pretty blurry though.

I wouldn't waste the electricity to grow out a male unless you're after seeds. The tiny bit of hash you could get just isn't worth it IMO.

If you have all males then you could flower them and collect the pollen in some baggies for some future breeding if you wanted but males just aren't worth the time to grow to make hash. I know you CAN do it but I wouldn't. I CAN do a lot of dumb things but I try not to. lol
