Clean lines, easiest-ever assembly, plant-optimized illumination, compact storage — this two-tier light stand has it all! Start seeds in spring and grow thriving houseplants year-round. The shelves unfold and lock securely, and each has a slide-in-place grow light panel that provides the ideal spectrum for plants. The lights daisy-chain into one main cord with an inline controller with timer (8, 12, and 16 hours) and dimmer settings. Simply fold up when not in use. Each shelf is a generous 28" long x 13-1/2" wide.
