I did alittle read on that CHH. From what I understand they say to decarb at 215? But alot of variables involved. Time being one. I seen with the rice cooker it was a violent boil and alcohol boils starts to boil at 180?, safe to say it was 200 for about 45 minutes. I even had to back down on the heat from time to time. I'd I'd imagine the cannabinoid THCA, is as close to it's pure raw form as it's going to get when it's suspended in a solvent, so it shouldn't take as much heat or as long to totally permeate? I've read this afew different places, not that I know for sure on any of this. But THCA will naturally decrab into THC at room temperature, that takes time and heat shortens that time. The heat from smoking decarbs pot as it vapourisers. Is why you get ALOT higher smoking a joint than just eating it. But I have gotten stoned eating raw hash? Least I think I remember was alot of years back I had to eat some of that Black Bubblegum Hash before the cops found it. I do remember being sick to my stomach in jail for the night. Oh well they didn't get the hash and I got out.
You know I'd imagine you have nothing to worry about having to decarb before making RSO,, if the man they named it after, not that he invented it, it's been around for along time, decades, does it that way, it's good enough for me. You should see the list of solvents that can be used. The ones that 'flash off' the fastest are some flammable shit. Shit like Hexane and Naptha could blow ya sky high. You want scary,, you should see what these big pharma companies use to break shit down with... Starting to sound like a chemistry set kicking off around here.
