Will be doing my first CO2 hash shortly. I am too lazy to read the ful thread and search site didn't get me what I wanted. What size should the dry ice chunks be? I am thinking 2 inch chunks. They even offer a 1/2" pellets. Herb prep: Best if it is fine shake? small nugs? How many times do you re-process each batch to make sure all keif is removed?
Rip the weed up don't grind it to fine cause the dry ice will get it so cold that the plant matter will freeze and crumble anyway.
Shake it over a large table, start at one end shake and slowly move down the table you'll notice the color go from golden to dark as it gets darker you are getting more plant and less keif
