MOCHEEBA, I think what you're asking is, will the three month drying time decarb the trim, or do you need to decarb it anyway? I'm not sure, frankly. The THC will decarb naturally over time, but I don't know how long it takes. I would decarb a small sample and see what you get.
One thing I do know is that if you do it in oil or butter, it should bubble as the CO2 is released. When it stops bubbling it is completely decarbed.
