My plant is about 30% brown hairs and 10% brown trichs, do i start flush at 50/50 brown haiirs or harvest then?
There is a thread on when to harvest. Go by your trichs, it seems that most people on here harvest when 50% trichs turn amber.
You can flush now if you do that sort of thing. I harvest when the trichomes are all cloudy (milky) and some are turning amber, I prefer the THC to CBD. Marijuana And Cannabinoids (THC, CBD, CBN...)
