sampling a premature bud, is like eating a green banana or coconut. Its edible, but a waste.
Wait till the calyx's turn or invest in a microscope. No need to "sample" just pick it when its ripe. Every plant in the same genotype will have a different sample, so whats the point ?
Uncured is garbage, any way you look at it
turn into what?!? calyx's dont turn...pistils doWait till the calyx's turn
