I don't think anyone answered the question, which is a good one. We all know how our scissors and fingers get gummed up when we initially trim weed; that's because the trichomes are wet like the rest of the plant. As the buds dry and cure, the trichomes also dry and voilá!! That's where all the wonderful kief comes from. That's why drying the sugar leaves and shaking them over a screen produces such nice hash-making kief.
My buds are very nice to handle by the time they get around 62-60% RH in jar. Yes, you always want to see the triches all over the bud, but they don't stay wet: they also dry out. It doesn't take long.
