Hang this lamp over your medicinal herbs during leafing and they’ll get all the energy they need to properly prepare for maximum flower production. Ideal for the shorter plants typically grown in closet plots and tent gardens, it soaks any 4' x 4' space in the specific full-spectrum wavelengths that stimulate the lush vegetative growth your harvest ultimately depends on. Ninety-degree reflectors assure uniform light delivery and rugged water-resistant housing stands up to moisture. You won’t be troubled by excess heat or energy use either because this lamp has a heat sink to keep plants happy and uses just 140 watts in the process. Guaranteed to maintain 90% or greater light output after three years of regular use, so it won’t let you or your crops down.
