Unfortunately I don't have a microscope...
It seems like my plants are maturing from the bottom-up so I'm just waiting for the top colas to look fully mature. I'm just trying to go off the pistils, they're about 30% brown on the bottom, working up to completely white on the top.

I was under the impression that it was better to hang the plants as a whole to dry to get the most resin out of them - is this complete fiction?
The razor technique sounds great, does anyone else have experience with this or have more info on the darkness method?

Again, thanks.
