This may be an old wives tale...I've seen no noticeable difference even if you leave them off for 4 or 5 days and then harvest. That's just me and the strains I mess with. I have a grow bro that insists on doing this and I don't and when we compare stuff grown from the exact same clones, exactly the same amount of time, there is no difference I, or he, can detect. Have at it tho and see if you can prove it one way or another...I think it's two or three days wasted to do this however IMHO.
TANKJR Reviewed by TANKJR on . When do you turn the lights out if your harvesting by Trichome colour? I have heard of some people shutting the lights off for the last 2 or 3 days before harvest.. I wanted to try this.. But am unsure of when I should be doing it.. as I typically harvest when I have about 30-40% amber trich's.. Would I wait untill this point and then turn the lights out? Or would I want to try and "guess" how close they are and try to shut them off 2-3 days before they get 30-40% amber? I guess Im just unclear as to wether the plant will continue to mature for the extra 2-3 Rating: 5
