Aou zapped my account for having a dream so I have to wait between replies. So I’ll explain it all. You take a grinder. You know it’s got the screen and little space below to catch the thc crystals. Like this https://images-na.ssl-images-amazon.com/images/I/51H2zkV2QVL._AC_SX679_.jpg See normally you can grind a shit ton of weed and barely get any keef from it. But you throw a coin in there and throw it in the freezer (I’ll be honest idk if freezing it does anything) but after you grind it you shake it around and that coin forces all the keef through the screen. So you get all the crystal off the weed. So you have shake and the keef seperated. You can vape or smoke the shake cause it still gets you high. Then you save all the vaped weed becauze aftwr you’ve cooked it it becomes edible but you need a lot of it because you’ve already beat the thc off it and vaped it. But this method allows you to get high a lot off the weed you buy. You can vape or smoke the shake and get a buzz. You can eat it and get blasted. And of course you can smoke the pure stuff and get blasted too. It’s a good way to stretch it out. It’s all I ever did once I started doing it
