I recently have been experimenting with this practice attempting to come out with that beautiful shatter consistency. while the end product is beautiful, it waxes up on me everytime. I have read on several forums and went thru the incredible skunk pharm site full of info. so here is my process for yall to critique. I start with dry fresh trim within a week of harvest usully. I don't frezee, the only thing I haven't tried yet. my trim is small buds and sugar leaf broken down to like u were to roll one up. I use a glass extraction tube and one coffee filter. I may try more than one next. my square glass collection tray sits in water inside of electric griddle on low heat. haven't measured temp but water never boils and I can stick my hand in there pretty sure its not decarbing at all. once I'm done blasting then I just let it sit till the bubbles stop and wether I whip or not it goes to wax by just sitting there. I have found when it looks like shatter it really needs some more purging. IME. what could I be doing wrong. I have used over 15 different strains too so I know that not it and my trim comes from to notch buds. so I tried to further refine after this by winterizing. all in all after two days of sitting in the freezer still came out wax lol lawdy lawdy what have I done! below on the flat parchment is winterized and cup is what I started with.
