dry hash:
i suggest if you wanna success and a good yeilder and not too green, the microne on a built trim bin and. Rubbing the just sugar trim and small nugs , every once I get 2-5 gram ish from such ( like a hours worth of trimming)
dry ice : key with dry ice is you need multple bags or they will freeze up than you have to wait for the screen to de freeze, when I do this method I have 3+ of the same main microne screen and be game.
ice extraction, not my thing even thou I did it for 10+ years cause not only is it nowhere near as fast to make your product cold enough to extract but everything , including your hash will be wet/ thou a additional “process and cure” vs dry extract where u can smoke it then and there if your stuff exactring is processed and cured.
dry hash or dry for me eh, everyone’s different
