You can look up how to make bubble hash. I've never had good luck with the ice water extraction. If I was you I'd make canna butter or canna oil to cook with. Just grind up the leaf (I use a coffee grinder) and mix a cup of finely ground leaf with a cup of oil and let it sit over night. Stir often. Then strain it in the morning. Your supposed to use cheese cloth but I didn't have any so I just used an old thin washcloth. That's all you have to do. Then you can make cookies, brownies or whatever you want to cook with it.
Yeah, and people use males for hash all the time. It doesn't have to have visible crystals to be worth while. I wouldn't smoke the shit, but for extraction purposes it's fine.
