how do you make your rosin hyroot? what return are you getting? 15%?
I smash a bud between parchment with a hair straightener around 250 F for 5-6 seconds. The oil / shatter squirts out of the buds onto the parchment. Then you collect with a dabber. With hash / ice wax, dry sift, kief. Smush between 25u -90u screen and have the screen between parchment. Use only either Reynolds brand parchment or Raw brand. Smush with a straightener.
Bubble man has how to rosin videos on you tube. Looked up Cuban grower and soil grown. There's also a rosin tech closed group on facebook too.
There also modified the shirt presses, Arbor presses, and neumatic presses out too. From d nail, high 5 vape, medisun, twitch extracts.
Stay away from rosin technologies and foundation extracts. They're shady and sell faulty everything.
