You have to look at trichomes with at least 30x, but preferably 60 or 100x. A pocket microscope is under $10. You harvest according to your taste, but most do it when the trichomes just start to turn amber. Pistils or hairs ain't got shit to do with harvest time. Search trichomes if you're going "huh?" This is "need to know" stuff.

I kinda thought the "whopping" part was supposed to be sarcastic, and there ain't no damn thc worms.
