With a new built-in timer, simply choose your lighting schedule with a single button press – 12 hours on/12 hours off or 18 hours on/6 hours off. Easy lamp height adjustment makes it a snap to direct light where plants need it most. Just plant seeds and use the simple toggle clamp to lower it to a few inches above the soil. Raise it as plants grow, staying 3 to 6” above the plant canopy. Includes T5 high output grow light fixture with 6400K full-spectrum lamp, Jump Start Light Stand and 6 ft. cord with on/off switch.
