Dry first then freeze.
I froze my trim green, when I finally decided to make bubble hash, I didn't worry about weight but I ended up with 4-6 grams.
My bubble hash had a greenish tinge.
when dried I pressed it together and baked it at 200 for 20 minutes then I rolled it out on parchment paper.
Froze that then folded it up and heated it once more and Then pressed it into a Container.
On my Ti nail, it will sit for 10-15 seconds then it will start to smoke.
Its so smooth that it takes a few hits to get a good buzz.
Not great in the flavor dept, but it's a first time producing more than a half gram of hash.
