Fine-tune your lighting system to provide optimum spectral energy levels that promote vigorous plant growth. Premium HPS grow bulb's provide up to 15% more available energy for plant growth than the standard high pressure sodium bulb.

Premium HPS grow bulb's enhanced spectral energy distribution is designed to grow a wider variety of plants. More energy in green yellow and red spectrum to enhance flowering. This band of light triggers hormones in plants to increase flowering/budding in plants.

Great for my cloning station Review by Mothership
I've got a small section of my room devoted to mothers and clones. This 400 watt bulb worked perfectly with my existing ballast and hood.
