I have questioned the 24 hour of darkness but always done it, been raised around old schoolers. I have said before on this board that I do it, but I have also said that I am not sure if it isn't a hippy tail. LOL
I don't do the 2 to 5 days of darkness to increase the resin at the end of harvest, I have seen too many tests that said that they had seen or noticed no difference. So maybe I am 1 for 1 on the hippy tails.
