I'm still lost. What is 'perfected'? Ice water, bags, agitation, squeeze, dry. Any method of extracting kief requires drying your flower, first. Water is not a solvent that would be extracting anything from the plant that dry sift doesn't have. Same bags, yeah?
I've had QWISO. Also RSO.
​My legit bubble hash experience was at my guy's house. I realized that day that he was moving some pretty heavy weight, a good portion came from his garage. Dude walks in with a bag of bud, throws it down. My guy gave bag-o-bud guy $1000. BOB whips out with a fist size mass wrapped in cellophane. I knew what it was and asked how much it was. I was asking the weight, not the cost. BOB pulls off a glob the size of my thumb and said it was free. It was damned sticky until it bubbled to ash. I wound up giving it to the kids at school.
