I used these for one grow only in a 2x4. On for 18 hours for 2 months and then on for 2.5 months for 12 hours a day. One cycle only and then I upgraded tents/lights.
My loss is your gain! Each light comes with a hanging yo-yo and I have the sticker pack but it has some plant material on it! Low power consumption+high energy efficiency, makes you get more yields than other brand led grow lights. Just enjoy the bumper harvest.
