Optimal Light Schedule For Cannabis
To optimize their yields, most growers give their plants a period of vegetative growth. That is because without it, the plants would not be tall or sturdy enough to bear big floral clusters.
You as a grower, determine the length of the vegetative stage by giving your cannabis plants enough hours of daily light so that the plants don’t start flowering.
Reducing The Power Bill
Indicas/Afghanicas comes from place that are relatively far from the equator. For that reason, they will start flowering even when the daylight hours exceed 12 hours.
The optimal light schedule for most hash plant landraces and Indica dominant hybrids such as OG Kush, Northern Lights or White Rhino is 13/11.
Start the flowering cycle with 13 hours of light per day and gradually reduce it to 11 hours of daily light over the course of about 10 weeks.
Pure Indian Sativa flowering under 11 hours of daily light.
