Hash bags made it here and so did wifes bday present...Today is a good day after all. Tomorrow comes dry ice and lots of hash/keif what ever it is....just gotta look up how to do it. I would guess use the smallest number then keep going up higher and keep it separate as different grades??
I would give the one sixty bag a shot for dry ice keif. All you have to do is put your trim in the bag, break up the dry ice so you have chunks in the trim instead of a big block of ice. Let it sit for a minute or three to start cooling your trim and then just start shaking it. You'll have a cloud of co2 coming out of the bottom of the bag, it's really cool looking but what's even more cool, you'll also see that keif starting to build up on whatever surface you are using. It shouldn't take more than five minutes of shaking to have a nice pile of keif.
If you're going to use the cold water extraction method, I would highly recommend using two five gallon buckets. In one bucket goes your bags, smallest micron size goes in first and the others in order until you have your two twenty shit catching bag as the last bag in. I beat my trim into submission with an electric drill and a drywall mixer attachment, it's heavy duty so the ice won't bend it and the openings in it are great to agitate your mix. You want to mix until you see a nice head of foam on the top and once that appears you just dump the whole thing into the other five containing your bags. This way you can mix in a bucket without fear of damaging your bags. Again, you want the ice to be as jagged as possible and the hardest part of making bubble hash as far as I'm concerned is to get the water/ice ratio correct. You should only use enough water to start that when you start 'drilling' your mixture, it's hard to get going because there doesn't seem to be enough ice...Edit. I meant water here. After a bit of mixing the ice will start to melt and you'll have more water. The key is to keep your mix as cold as possible and not use a ton of water. It's one of those things you just have to do a few times to understand. Consider your first couple of runs a trial and error period.
