What are trichomes
Trichomes are those shiny and sticky crystals that wash over your plant with potency goodness. Or in plainer words; they are the resin that contains that majority of the cannabinoids (THC, CBD, CBN, etc.). Your THC cannabinoids are at the highest when the trichome is cloudy, hence why we want to harvest then. When the trichomes turn amber the THC is converted to CBN.
Important note: So many people confuse CBN (cannabinol) with CBD (cannabidiol). They are both cannabinoids that have relaxing effects, but CBD has a much larger effect on our bodies compared to CBN. Many growers think they can alter their THC and CBD ratio by harvesting earlier, or later when the trichomes have changed to amber, but this is not true. There are hundreds of different cannabinoids in cannabis and they all contribute in some way to the plant whether it’s the high or aroma. Do a quick google search for the term “cannabinoid chart” if you’re interested.
