Yeah that takes a while to get the feel for but that’s pretty much what it is, I feel a medium size bud, give it a pinch and see how it responds, if it stays flat - then still too wet. When the pinched bud springs back some after being pinched then it’s about ready for the slow dry.
I have another hopefully more precise and less subjective method to test bud dryness that I’ll be trying out and documenting with my upcoming Banana Kush harvest, involves using a moisture meter to test the buds for moisture content, something that came up in the Grove Bags thread. This could be a huge help for new growers. Basically test buds until they show a certain level of moisture content. See my banana kush grow journal in a few weeks as I will detail the process of checking and what numbers I’ll be looking for.
The type of moisture meter I’m talking about:
