I only could find 91% so I went ahead and used that with around a half ounce of trim and lower buds from the NL grow, and did the frozen ISO, material and jars technique with a single 30 second wash time then filtered through a small mess strainer and unbleached coffee filters. I threw a flat griddle on top of my flat-top burners followed by a large ceramic coated metal baking dish filled with water, and once the water read 180f/82c I put the pyrex dish I'd filtered the ISO though into the bath, opened up all the windows in the room and turned on the hood fan and left the room for 20 minutes, when I came back there was only a very little ISO left so I spread it out and left for another 5 minutes, when I came back it was all evaporated and I took it off, scraped it and rolled it together in a piece of parchment, and put it in a little plastic container I have. I've since had a chance to sample it and it is incredible, almost instant numbing and mind erase with an intense stone settling into a great chill. Going to throw up a pic, it isn't the prettiest thing, but it does the trick. I read an article on Skunk Pharm Research about them taking their trim/bud down to 15% humidity before extraction and think I may try it in the future to try to get a cleaner overall finished product. Anyway, thanks for reading!
