The whole checking the trichs thing is kinda new to me, I came up judging more by overall look and 'feeling'. I don't know that I've had a plant that ripened uniformly so I guess given the opportunity I would go for 75-80% Milky 10-15% amber, and the rest under developed or somewhere in between. I imagine the trichs undergo ripening post harvest to some extent?
It seems like some life stuff always happens though that dictates my need to harvest enough so that I end up harvesting at whatever point seems good enough in relation to my stress level about the whole thing
. However it works out I find that my homegrown usually gets me stoneder than the stuff I encounter elsewhere and that's all that really matters at the end of the day.
