You dont NEED a hash maker, just makes it easier, and yes, hash is just the compressed keef. Keef is basically pure THC.

If your gunenr grow, make it easy on yourself. Forget about leaves, its a waste of time. Kill all males, pull the balls from hermies, and flower the females.

You need to do a bit of reading before you can grow... you dont seem to know much at all (Thats not an insult)
