Tomato grow lights (or plant grow lights) allow you to start seedlings and grow tomatoes indoors, even during the off season or when temperatures are cold outside. Grow lights provide an electrical equivalent to sunlight. Surprise â¦ plants need darkness as well as light in order to grow best!
When starting seeds of other garden crops indoors under lights, the lights should be left on for 18-24 hours per day, but having them on that long for onion seedlings can affect the bulb set. Instead, leave them on for only about 12 hours per day. Plant onion seeds in clean nursery flats using sterile, seed-starting potting mix.
