Collection: Grow Light Lamp Bulbs

 

HPS Grow Lights

HPS (High-Pressure Sodium) and MH (Metal Halide) bulbs have been the go-to choice for indoor growers for decades — and for good reason. Both are HID (High-Intensity Discharge) lights that produce the kind of light plants actually need for strong growth and development.

MH bulbs give off a cool, bluish-white light that’s perfect for the vegetative stage — helping your plants develop strong roots, stems, and leafy growth early on. HPS bulbs, on the other hand, emit a warm red-orange spectrum that’s ideal for the flowering phase, encouraging bigger blooms and better yields.

You can run them separately or use them together with the right ballast to support your plants through every stage of their life cycle.
