My first attempt at dry ice hash! I'd call it a success, a noobie success perhaps, but a success regardless. I started with one pound of very dry MamaThai x Pineapple Chuck which is a very dense and resinous producer. I crumbled the flower by hand as gently as possible and sieved it first through a 72 micron screen with about 5 pounds of crushed dry ice. The resultant hash is a very nice blonde, but in retrospect I should have ceased extraction at the very first sign of green. The balance of the extraction was done with a 120 micron screen and the result is much more green. I don't use cannabis. I used to wake and bake, but it just isn't for me anymore. I grow for my brother's medical needs and have done 200 proof EtOH extractions with vacuum assist and almost complete recovery of the alcohol. My raison d'être is learning and experimentation, and the ultimate goal with the dry ice method is twofold; to reduce the time to derive a decarboxylated medically beneficial product for mixing with MCT for sublingual use, and to produce a concentrated natural resin with which to test dissolution times and solute concentration limits in EtOH. My yield was 2.0ozs of blonde and 2.4ozs of green. Good times.
