I made a batch of "RSO". I used 99.9 ISO and 1 oz of good well trimmed, decarbed bud. I read in several places that I should expect 3-5 grams yield...I ended up with 17 grams. Followed the directions and cooked it down adding a dropper full of water at the end and cooking that off. There are absolutely no bubbles in the stuff after 4-5 hours on a coffee cup warmer. At room temperature, it stays liquid...put in the refrigerator and it stiffens up immediately. Hard to weigh out dose when it is liquid and hard to force it through a syringe when its cold. I'm certain all the iso and water are gone. So why do I have 17 grams instead of 3-5? Any ideas on where I went wrong?
