What is the vegetative cycle of marijuana?
This is a period of growth where a plant receives more than 14 hours of light per day. Regular lighting schedules for this period are between 18/6hrs – 24/0hrs of light. During this period the plant directs its energy resources primarily to the growth of leaves, stems, and roots (I.e. no buds form). 20/4 is a extremely popular veg cycle as well but in reality any light/dark cycle that keeps a plant in 14 or more hours of light with less than 10 hours of darkness is considered a veg cycle.
