just starting out and i have not been able to find anything to helpme with how long or how often i should keep my lights on when i first sow my seeds.
how long do i keep my grow lights on when i sow my seeds?
I turn my lights on first thing in the morning and off when I go to bed.
12-16 hours is a good rule of thumb. Don't leave them on 24 hours a day ... they need darkness too!
