from my understanding its a very slight increase in resin,,,,,,,, but the best thing that intrigued me was that since the lights arent on, the chlorophyll gets used away and makes for better tasting buds,, since the lush green grassy flavor isnt in for sure..
jorge says 24- 48 hour dark period!! also you harvest right as lights on, or right as lights were supposed to come on anyways extending the dark period may or may not do much, but im always with jorge!!
If your talking about Jorge C. He spits alot of bologna in my opinion though he does have some good tips
