The hairs turning brown is no way to tell. It's all different for different strains. You need a $8 pocket microscope from Radio Shack to look at trichomes.

OK, so Ive done a rather stupid thing and paid more attention to bugs than my plant in general, and Ive just noticed that ALL the pistils - bar one or two - are brown. Sadly I dont have a microscope (well I do have one that a mate lent me, but its not powerful enough to see the trichs) and Ive just remembered that you harvest when 75% of pistils are brown. Well, thats rather vague as we all know, but I dont have the luxury of a 30x microscope. So, do I harvest now or wait a few more days? Rating: 5
