I was actually wondering the same.. I have a few plants (Papaya from Nirvanna) and one of em is just about ready to chop. It's prob at about 20% Amber right now. I'm more of a Sativa guy myself.. I like clear up and go highs.. but i def wanna feel it. So I guess I'm gonna cut in a day or 2! Will post pics ;]
Yeah, you always here what kind of high what color trichomes give you, but never what people personally cut at. I was thinking about doing a little under 1/2 amber and then cut.
