Shop your next HPS & MH grow light online and in store at Grow Kings. Our collection features a massive range of high-pressure sodium (HPS) and metal halide (MH) grow light systems, including HPS MH bulbs and full light kits.
HPS and MH grow lights are renowned for their intensity, broad-spectrum illumination, and consistent light output, making them suitable for all stages of plant growth. This means you can use the same grow light system from the cloning or seedling phase right through to the plant's maturity and harvest.
The key difference between these two types of lights lies in the spectrum of light they emit. MH grow lights produce a blue spectrum that is ideal for the vegetative growth phase of plants, encouraging strong, healthy development. On the other hand, HPS grow lights emit a redder spectrum, which is optimal for the flowering or blooming phase, promoting lush, abundant blooms.
Explore our selection at Grow Kings and find the right HPS or MH lighting system to meet your growing needs.
