For the benefit of anyone finding themselves here (looking at you @Hank68), @Storm has achieved crystallization of thca, but not “diamonds”.
This “sugar” could absolutely be post processed to “thca isolate” using YOC Dirty Diamond Tek - THCa isolation from Crude
Then turned into “diamonds” by ReXing THCa in pentane
Not saying you can’t grow “diamonds” in ethanol. Just that that is not what has been demonstrated here (yet).
