I looked into qwiso on this site last night... so I decided to try it. I had 3 grams of some grade a nug (some serious dank! ) lol and threw it in a mason jar. I then washed it for 30 sec strained and evaped the same way I do my butane hash.. the result 1 gram of some really sticky gold hash!! Thats a huge yeild from what im used to frok bho .. the thing is that I dabbed it and it taste super good. I think im gonna get more into iso extractions because butane is expensive lol.. this stuff taste really pure and better then anyone bho I have ever tried ( besides what I make because I only use bud) .. any thoughts guys?? This stuff fully melts and is jus as good as bho.. jus safer and easyier and cheaper to make I guess is what im getting at.. send your thought s this way! Maybe some comparison photos??
