Sunlight is THE best, it is free, easy and has every light spectrum your plant needs!
There is nothing better than natural sunlight!
Your plant can have every minute of sun that is available, from sunrise to sunset, the more the better!
For best cannabinoid production, a minimum of 6 hours of direct sun is needed, anything more is even better.
If this plant is an autoflowering type, she can have up to a combined maximum of sun and LED for a total of 18 hours.
If this plant is a photoperiod plant, 12 hours of total light time is needed, anything more will cause her to go back to vegetative growth and stop flowering.
Hope this helps,............
