years and decades ago, People just waited as long as you can to harvest, the longer the better, full red trichomes was more common...
its a powerful difference from what you see today...step over into dreamland, late harvest borders on the psychedelic....
everyone pics for near peak THC these days, but we know thats just a very small part of the effective cannibinoids ...as the trichs turn more and more amber /red , lots of the THC is converting into CBN...and other compounds, resins and oils really start packing weight on the buds as well...and flavors get stronger...
if you never tried late harvest, give it a shot.
