So I've started all types of plants, tomato, pepper, eggplant, squash, brassicas indoors. I also grow lettuce 100% indoors under LED grow lights. Lettuce does well for the most part. I tried growing spinach and it sort of gets stemmy or goes to seed very quickly. Doesn't get large leaves at all. I've tried different varieties and same thing.
Has anyone tried growing spinach for harvesting under led grow lights and had success?
