The little greenish turdette of kitchen sieve junk that I made reminds me of the stuff from the old days but more potent. I have also read that with dry ice, the mesh size makes less difference Than with bubble or dry sift, but the amount of time that you actually shake is more important. I’ve seen videos of a couple of guys using 160 or 220 bubble bags and they were still getting the real pale blonde stuff at the beginning and the more they shook the more brown/green the powder got
I noticed that the dry ice breaks the plant down to tiny bits of material that will pass through the higher number bubble bags but I'm not trying for any full melt hash. I wouldn't even know how to smoke something like that. The hash I make reminds me of the hash from the 70's and 80's I had access to. It also seems like a better option to store for long periods since it is easily frozen.
