I have done it more than once, but sure I’ll sum it up. Thought about it but figured I was repeating myself too much.
The way I do it, it is part patience, part freezer, and part crushing technique.
Patience:
You gotta wait til the trim is dry as a bone. I put mine under a fan to accelerate the process. This is vitally important.
Freezer:
If drying it completely is first, the freezer is next. I put the trim into gallon storage bags. Then I suck the air out. This is also very important. If you freeze your trim before it’s super dry or fail to remove the air from the bag before freezing, all that effort is for naught. The air will condense as soon as you remove it from the freezer and it hits the tray with moisture. Or the moisture in it will freeze and thaw in the tray. Once the air is out just freeze the bag or bags overnight.
Crushing Technique:
Now you have the empty trim bin and a frozen bag of trim. Do not dump a whole gallon of trim into the bin at one time. More like a third to half at the most. That way you are maxing the removal on each batch. When you overload, you leave a ton on the table and if you try to rekief it you will get green. Green is death to kief. So only enough at a time to cover the bottom an inch or two.
Then - I use a bare hand. Shake the trim to one side. Grab a big handful and move to center (open area) of bin, near center of screen. Then, with a flat palm, GENTLY cover as much as you can and press down lightly on the trim while using a circular, rotating motion to break that handful down. A rotating motion is far more effective than back and forth. If you have done it right, this will break down relatively quickly. Then grab another handful and repeat til you got it all. Then put it all in the middle and do a final light pass to get broken down anything you missed. DO NOT CRUSH IT TO DUST. If you do you’ll get a ton of green. The idea is to break it down completely without making any dust.
When that batch is done, set it aside. It’s done for kiefing but if you’re a butter/edibles person it still has enough juice for that too. Repeat for entire bag, setting aside each batch as you do it in a box or whatever.
Then, last step, re-dump the entire gallon you began with, now set aside for edibles, back into the bin. DO NOT TOUCH IT WITH YOUR HANDS. Instead, shake it to the center and take the whole bin, lift it off a table, and bang it onto the table as hard as you can without spilling it all. Do that two or three times.
Remove top screen part of bin, use small brush to transfer to storage container. You’ll have more than you imagined was possible every time.
I let mine sit out in a bowl for as many days as necessary to make sure it is bone bone dry before permanently jarring. You can jar it less than super dry if you like, and if you let it sit that was for like a year, it will cure, get better, and become what I call “half-hash.” Or I just top bong hits with a dash when I want to or need to for pain.
Did that do it
