A grow light under 300 W suits seed starting, herbs, leafy greens and houseplants, or a 2x2 to 3x3 ft tent with a few pepper or tomato plants. Most hang from a tent bar or a shelf on adjustable cords, and the dimmable ones can be turned down for young seedlings and up as plants grow. A 100 W panel is enough for a seed starting shelf; a 150 to 200 W light covers a small tent of fruiting plants.
