Everytime I buy weed I take it out of the bag & put it in a container with desiccant. You know how sometimes the weed you get will be like super crispy? This will make it that way. It just crumbles right out of your fingers into the bowl. The bottle doesn't need to be completely sealed. Don't think it matters. I got this idea from my friend. I complained that I liked bone dry weed and all the shit I was getting was moist (by my standards at least) and he said if I left weed in a dresser drawer overnight, it'd be crispy next morning (Even just simply leaving your weed out will get it crispy eventually, I discovered). I originally thought the misture was due to a plant's particular resin content or whatever, but much to my surprise, he was right. Being the optimizer that I am, I came up with the desiccant idea. Today I discovered that it only takes like 45 minutes to significantly dehydrate like an eighth.
