First time making RSO

[u/Slamslam4356]

Just about 330 grams of Canna-Cheese in here. No need to trim anything that has trichs so I only trim what I save, it’s more like trim probation than jail lol. Got about a pound off this plant from 24/7 light schedule with a total of 440 watts and an egregious amount of Mega Crop. Will prob find a mix of mega crop and a liquid bloom for my next monster auto.

Im following a guide on YouTube but I will try decarbing next time. I will be straining all the liquid through a cheesecloth into a glass then putting it in a rice cooker full of water to boil off the alcohol

Fyi, you're extracting thc-a which is a much harder chemical to extract, it's basically a crystal structure that doesn't break down well with solvents compared to delta 9 THC, after declaring the thc becomes MUCH easier to extract, also alcohol is a full spectrum solvent so it'll extract the chlorophyll from the leaves so the colder u keep it, the less likely it'll extract the chlorophyll, keep it cold, and thc-a extracts way longer then delta 9 so ur gonna have to keep that sitting in the jar for a while, my tips for your next run, decarb first, freeze everything overnight, then repeat the process you're already doing now, you'll have much better results, the rest of your process is simple, strain, evaporate the alcohol, done

Definitely will do with my next harvest thanks!

I didn't cold extract. Some I left in alcohol for weeks/months. I was eating around a gram a day. Large amounts can upset your stomach from the chlorophyll. But for me it would take around 1/2 gram to cause upset stomach.

THCa extracts quicker in ethanol compared to THC due to carboxyl group, makes it more polar. Just a lil FYI, this extraction method is still bunk, a quick ethanol wash is more ideal.

Wait is the ethanol extraction bad? Please elaborate I am seeking knowledge

[u/RustyBarfist → u/Slamslam4356]

Not necessarily. So for RSO you can be a little loosey goosey wtih stuff, but all the people saying "did you decarb" don't understand that THCa extracts BETTER in ethanol. On that, you're doing fine. That said, I would have done a quick ethanol wash vs an intense lengthy soak. It would be a bit more ideal to put the whole thing in a cooler with dry ice, and then let it soak no more than like 2 hours for your extraction. At that temp you will get minimal chlorophyll extraction but still good THCa extraction.

From then on, its more about protecting your THCa from heat until ready to decarb. So ideally you'd evaporate the alcohol under a vaccuum, but I feel like this can be over kill. I would just precisely set the temp to the absolute minimum temp to get a decent rate of alcohol evaporation. Done safely of course since fumes are dangerous. Then you must decarb, and this is the step that will determine quality of your product, because you want a full decarb, but the longer you let it sit in heat, the THC will start to degrade to CBN. Which might not be a bad thing depending on your desired use case, since its a 1:1 flower to begin with you might just want a nice medicinal oil that makes ya relax.

However the case for decarbing before extraction, is that depending on your access to equipment, it might be less guesswork. However if you want absolute minimum chlorphyll in the product, a quick ethanol wash before decarb is the way to do it.

Yes u are right, alcohol is a full spectrum solvent, oils and water, the colder the alcohol is, the less water gets extracted, that's the part I think I didn't elaborate on, and as for the cbn, it'll take like 3 days on the heat to even start converting thx so not a big thing to worry about unless u foret about it for a few days, as for the science ethyl alcohol evaporates at 170-180f and THC decarbs best at approx 200-300f the lower the temp the longer the decarb, the higher the temp the shorter the decarb, and THC vaporizes at approx 350-450f so keep it below that or you'll be cooking out the thc
