hey man, there's a lot of FUD about the dark period, basically the main idea is that there's little you can do in the last 48 hours of a 3 month grow that will do something significant on the grow overall. but the dark period for sure has some benefits, for example a dark period before the chop means less photosynthesis chemicals present for the dry + cure. Second the dark period will boost the creation of terpenes. some say it's good for thc, but trychomes take 2 weeks or more to really make THC, so that"s FUD. second thing is that on planet earth it's almost never dark for two days straight, anything really more than 24H and for sure 48H will start messing with the trychomes and they could oxidise which is bad because you loose that much in potency. Hope this clears this up a bit, good luck ! 🚀
