i would go from 8 to 9 weeks... i have grown northern lights and between the 8th and the 9th is the best time.


About the trychomes, first they are clear, thc levels are low, then they get cloudy, thc levels, get high, then they get amber, the thc levels are going down due a transformation of the substnaces.

The best moment to harvest is when they are 70% cludy 30% amber, so the high is higher, and the body stone is lower, the more amber they get the tougher the body stone is, but youll know what im talking to you, once you get a microscope and check out by yourself your trychlomes... anyway here is a little guide
