hey Justnblaze, dark period is important why? well three reasons, first of all after a dark period of 12hrs or less the plant has less photosynthesis chemicals in it which means the "cure will be better", aka a smoother better smoke. Second THC and terpenes actually get degraded by light so what happens when the lights come on the teprs and thc get burnt off so a dark period at the end allows the plant to "catch up" and get that flavour and strength in there. Getting strong weed is 50% growing and 50% curing, THC also comes from the cure actually ! a dark period of 12-24hrs helps, in fact you should chop and dry in the dark too, because once you chop the cure starts and light is the enemy of the cure. So the difference is a better, fuller taste and a stronger more potent smoke. Anything above 24hrs of dark and the trychomes start degrading though. hope this helps ! 🚀
