My first run with Dry Ice I used a DVD container.
A couple dollars worth of dry ice was more than enough.
I used some 120 micron silkscreen I had and got an excellent batch off some Purple Kush trim.
This time I went with 200 micron screen and the results were even better.
After you have the trim or bud and dry ice in and the top sealed let it sit for 5 or 10 minutes to chill out.
Flip it and shake it for about 1 minute or less. This first run will be the very best, collect it and set it aside for personnel stash.
If you shake too long you will just reduce all the plant material to dust and end up with crap. You just want to knock the trichomes off through the screen.
After you have your Kief put it in a hash press and heat it to around 120 degrees for a couple minutes and your done.
No water, no ice cubes, minimal mess and the finest hash you can find if you do it right.
