I have used dry ice to cure it before, just crushed it up and dumped it over the top after i hung it for a few days. I put it in a box with lots of holes poked in the sides. IT seemed to work decent. The smell was definitely there. I agree most people are fucking up the curing process. I get such beautiful weed sometimes and i go to smell it, and it smells like fungus or an attic, it disgusting. All these mfers growing out in the country curing there shit in old ass tobacco barns and dank dark places... YOUR WEED SMELLS LIKE WHERE YOU DRY IT. Oxidation is a ferocious force of nature constantly happening in the air. Its a war, as soon as you cut your weed down its at war with preservation. That smell, that beautiful dank lucious gods vagina smell, is the most delicate and thus the most fleeting and suseptable to oxidizers.
Dry ice curing is good, but expensive... Check your local provider, it aint cheap. a
Its all about that level of detail you want to take it too, some folks scoff at a level of sofistication that high, me, Ill smoke it all, but im a connesseiur, and I like when my weed sucks me in and I have to keep smelling it over and over. That shit is few and far between, but hell, thats most shit these days, mfers in here on a get rich quick scheme wont develop an eye for detail or palette for detail, there is just very few passionate artists consumed with their craft, hell its just like growing tomatoes and strawberries, and we have all seen the wackness they sell at the grocery store and farmers market.
I produce for 4 peoples personal use. Im not trying to move weight. So a little exra money for dry ice is warranted, after looking at them under the microscope, they didnt look mishandled afterwards. The resin has the same characteristics as a fat and is not brittle when frozen. Its hard like a rock.
