I would just like to make a correction to what
@BubblinBuds said earlier. As amber increases,
CBN is produced not CDB.
I’m with
@bluter on this one. Your trichome density is a direct result of the overall health of the plant as it goes through flower. The more dialed in your VPD, and the denser the photons in your lights, the more healthy, robust your plants will be... thus more potent. The stem splitting, temp manipulation, extended dark period, etc... all these techniques are like
@multiVortex said, ‘sprinkles on top.’ ...and that’s at best. At worst, they could potentially be a detriment to a plant in a less than idea environment.
