I keep my grow lights on for 12-14 hours a day . The light should be no more than 2" above the seedlings. I also grow my seedlings in a cool basement room . If doing 8 hours a day your seedlings will stretch to try and get more light.Marigolds are sprouting, as are some of the leafy greens!And my onion seeds arrived yesterday! Must get those started this weekend, along with the arugula.
Offhand does anyone know if 8 hours on the grow light is too much for spinach, leaf lettuce etc? I’m tempted to take them off the light, I don’t want them to bolt before I can harvest them (again).
