Hey brother.I have read a few different ways to do it.anythng from 24 hours to 5 days.And Im sure your aware that what it does as it lets the THC build.I personally left my Blueberry headband in the dark for a touch over 36 hours cause I was an uber newbie and didnt wanna the world to implode.LOL!BUT, I left my second and first Auto and another Photo in the dark for three days and I truly found there was a diff. to me.It was truly glossy.Youll see the diff. but Im faaar from a pro and have only done it twice.But I can tell you that in my humble opinion brother,Id leave it in the dark for three days and have the soil only slightly damp.Thats what Ive read and have tried.
It gains tons of energy and potency.Happy harvest brother.!Be well!!
I forgot to mention that youll be able to see a bit (A lot in my case) of a diff. since the buds and all the trics are just truly wet looking.So in just a visual aspect they look sweeter,sexier and just more luscious.But Jorge Cervantes says it can make a diff. with even 24 hours since all bio organisims(I kno I cant spell LOL) gain energy and strength when sleeping.I do it,you prolly feel better after a goodnight sleep too.Jorge and I can very well be wrong. maybe it is a myth.I wonder where one would go to find more of an intricate understanding of that question.hmmmmmm.......Pondering the ways of the world.well if I am indeed wrong,I hope Im not giving you terrible or even bad information.Ill have to read up on that a bit more.I'll try to get back to you on that brother.sorry if its bad intel.Be well my friend.
