One oz of trim? Just one oz of trim to a pound of butter? One oz of trim equals maybe a ¼oz of buds, potency-wise. That means the potency of that lb of budder is probably only 2000mg of THC or so, total, rough estimate. If you have an extreeeeeeemely low tolerance, you should be very happy. However, I suspect you’re going to need to ingest a lot of budder to properly dose yourself.
Why are you differentiating between decarbing and cooking? What made you label them as 2 separate things? Did you use different settings?
