@jeddyeff if your RSO is actually testing at 75%, I’d recommend a new lab.
65% seems like a more reasonable number. 75% would require -80C ethanol and very short incubation times. 75% THCA is achievable with ethanol, but Rick wouldn’t put his name on it until it was decarbed. at which point it would be 75% x 0.877 = 65.8% THC.
Ideally, you’re shooting for better than 90% THC, but it’s easy to miss. eg: Reading test results
if you’re new to the game, or develop a leak in your setup after playing for a while, and don’t notice, you can also take your 65% crude, to a lower potency than you started with. eg 53% THC as shown in What happened here?
To understand what’s going one, try this video THC Imposters (Isomers).
Chromatogram: 3% THC - #6 by 420fathermckenzie shows an example of 3% THC (made from 65-70% THC crude).
if your RSO is so green it’s black, then 55-60% THC is a more likely potency. I’ve seen RSO being sold in syringes at 19%THC. No idea how that was achieved.
My boss has started calling the 65-70% EtOH crude we’ve been making RSO again…because it’s a name folks recognize… even if Rick wouldn’t recognize the product
