48 hours of darkness before harvest ?

Just useless, broscience.

Simplify it just harvest in the morning before lights come on and cook the crap out of your resin glands

It is crap. 48 hours of darkness just stops the plants metabolism. A plant with stopped metabolism will not be able to prevent THC breaking down. Fact. Do not do it.

darkness before harvest slightly increase thc but significantly reduce terpene concentration. (baked with lab result: www.youtube.com/watch if you doesn't have a you tube account i have a screenshot of the results in this diary: growdiaries.com/diaries/27422-12-12-from-seed-chupa-bud i personnally prefer having more terpene over few thc %

Its a big fat myth but some people like to do it. It says it helps build up terpenes in the plant and cannabinoids. but not by anything significant if it even does. The increased smells are influenced by the tent being colder with lights off and the terpenes building up in higher concentrations. Do normal lights off and chop next day whenever without turning them back on. Does not need to be 48hrs. Dry/Cure works best in darkness and lower temps with stable RH around 50-60% Good Luck!

if I was u I'll wait till harvest day , chop her up and then dry her in the dark.

Hi mate, at the end of your last day shut the light off for 2-3days keep air circulating fans on an all good, best to not water a couple of day before and flush as usual if do so. Hope this helps Good luck
