The Digital Nomad Posted October 2, 2012 Report Share Posted October 2, 2012 I recently did a Dry Ice Extraction from buds with seeds. I knew that we could not process the seeded buds in Ice Water Extraction - as the seeds can leach taste in to the mix as the paint mixer breaks up the material in the ice water. Butane - you still have to clean out the seeds and stems. With Dry Ice, the sharp edges of the dry ice will pulverize the bud material - leaving the seeds intact, along with small stems. I have used 45 micro and above is 73 micron bags. Coffee can, dry ice broken into 'gravel sized pieces'. You just sissor the buds to medium to small peices - you DO NOT grind the mix - even if you did not have seeds - you want to avoid plant material from being small enough to pass through the screen. The above results are from 8 runs, at 10 - 15 minutes shaking, cooling, etc. each run. The Dry Ice method requires some elbow grease, you will shake that can on and off for several minutes at a time, for about 15 minutes or so. You can add more bud/trim to the mix and do this over. But after two runs, the dry ice has rounded off its edges, the plant material is now 'dust' and powder. just like making Ice water hash - the first part of the run is the prime trichromes. the longer you go, the more small plant material that might filter. With practice, you will know when to stop. Dry Ice - Meijer's - 1 lb - $12. - the surface- you need a VERY large CLEAN surface like a mirror. I used a 3 foot by 4 foot mirror - and I still had 'hash dust' go all over! Use a very sharp and clean Plastic card to collect the keif off the mirror. Use another plastic card to remove the keif from the plastic card, avoid touching with fingers - as the trichromes will melt with body temp heat. Collect in the glass jars above, and compress it as much as you can. It becomes chunk like. You can roll in foil and keep mashing it, body temp and compressing it to make bricks of hash. Ice is inert - it has no residue like Butane or ISO. Dry Ice is - dry - so you have no risk of mold. Dry Ice also allows the smell of the strain to transfer than Ice water method. You can use the same bag you use for Bubblebag or Ice water - except - the 1 gallon sized bags are best because you can hold the coffee can easier. You do not want to do this with a 5 gallon bucket shaking over a mirror. You can process trim or buds with this - again - do not pulverize or grind prior - just replace the dry ice chunks often to keep sharp edges on them. Do not process the leftovers with BHO - tried it - the material is too fine and will pass through most BHO filters to make your BHO, green ugh.
