I am searching the forum for indoor spinach advice. Did anything work for you when you adjusted the light schedule? My seeds germinated fine, the sprouts looked good and strong. I replanted them on 12/5 and they had some growth initially, but have stopped. I'm not sure if my light is too strong, too dim, on too long, not on long enough, too close, or not close enough. Currently the light is 12 inches from the tops with a 13 hour on daily schedule.
