There is no proof one way or the other. It has been tried by many, many and some say its helps and others say it does not.

Personally I would want the plant to use up the stored chlorophyll to help improve the taste and speed up the cure time so I don't. The plant needs light to complete the chlorophyll process so if there is no light then the plant can't burn up the stored energy.

Its up to you there is no proof one way or the other beyond antidotal evidence.
Zandor Reviewed by Zandor on . dark period after bloom ive heard alot of ppl put ther plants in a dark period for upto 72 hours before harvest... is ther much benifit to this? im currently ready to harvest but i have one plant thats a week or so behind, so i wana leave that in ther, so to put my other plants in a dark period will be a bit of a mission, if its not worth it i wont bother... cheers any advice would be appreciated.
