Our most innovative grow lights yet! Grow more indoors than ever before with this stackable, high-performing system. We successfully grew rosemary, lavender, greens, kale — even dwarf cherry tomatoes. And our geraniums bloomed as profusely as they do outside. Two 3690-lumen grow lamps satisfy all your plants’ light needs from a fixed height. And, because the bulbs are recessed, there’s no glare.
