I set a timer, it starts lighting at 7 AM and ends it at 7 PM.
These LED lights don't use much wattage per hour.
I don't know if the growth could benefit from longer light exposion, so I guess this range of hours could be fine.
The problem is cold because it slows growth, not for freeze because we don't have heavy freezing and the little seedlings were in a cold frame, the real problem I guess is the deficiency of sun light.
So, I will take a pic every week if I see real changes with the seedlings and make a small report on here, if it can be useful.
