Hello. I use 3 days of darkness myself. It improves the taste. I also don't water for those days and it is much easier to pick up the pots. It is part of my drying process. At this point, the stress, I think, helps the buzz to be more of a head buzz and less of the body buzz. Try it once, see what you think. I like it, it's part of what I do now. Good Luck. Chuck.
