GE LED Grow Light for Indoor Plants with advanced red-light spectrum for flowers and fruit is designed to fit your plant's growth stage. Grow Light uses an advanced red-light spectrum that allows plant pigments to optimize their light harvesting and inspired by best practices used by professional growers. It is designed for mature plants at the fruiting or flowering growth stage. Compared to typical purple grow lights, the light features high PPF - photosynthetic photon flux, to provide more light for photosynthesis and growth. The white light appears more natural to the human eye, so you can appreciate your plant's beauty and spot pests or discolorations to help keep your plants healthy. Use the advanced red-light spectrum with high light plants like tomatoes, cucumbers and peppers at the fruiting or flowering stage of growth.
