This subject seems to come up every few months, so let's get at it; :beatdeadhorse: .

Sorry 'Wonder, plants don't need darkness to work on root developement. "Roots grow in the dark, but not when it is dark". In fact most "experts" reccomend 24/0, low level blue dominate light to root cuttings. If a plant needed a dark period to "work on root developement" you would not be able to produce clones with this method.

There is a certian amount of cell division that takes place during the dark period, it envolves the root cap grow points, but what it is making is a lubricant for the tap roots for when they go back to growing.

Scientific studies of plants in general and cannabis in particular, shows there is no harm to the plant using 24/0 for vegative growth. Meaning they do a flower stage very normally even after such treatment.

BTW: plants don't "rest" during the dark period, if you study them and what they do you'll find that plants are 24 hour factories.
