Yeah i not done the 2 dark days.
Get to know a strain for a year or so then try it or do 50% of crop next time and see if there a difference.
I think drying in the dark brings it out just as much personally and due to the amount of plants/ grows at the moment i have tried a veriety of different chopping times and conditions ( morning, night, warm, cold, dried in dark, in light, chopped early, left to couch lock. )
Personally my best looking and tasting green came from an 9 week flower PP girl chopped early morning just before the lights came on and dried in a dark cool cupboard with a desk fan blowing near not on it.
As the outside felt dry but still obviously sticky in middle it got put in McDonalds brown paper bags for 4 days been turned twice a day then into sealabe tub or preferably jar.
Strongest was 12 weeks and thrown on a rack to dry, no special treatment at all
