What Are Sunmaster Cool Deluxe Metal Halide (MH) Grow Lamps?

Sunmaster Cool Deluxe Metal Halide (MH) Grow Lamps are a Metal Halide (MH) bulb. They're available in a range of wattages, all with E40 fittings. MH bulbs output more of the blue light spectrum. They're specifically engineered for early growth and vegetation.

Why Use Sunmaster Cool Deluxe Metal Halide (MH) Grow Lamps For Vegetative Growth?

Sunmaster Cool Deluxe Metal Halide (MH) Grow Lamps are chemically balanced to produce as much photosynthetically active radiation (PAR) output as possible. The PAR measure is the total light available for photosynthesis.

The plants can use most of the light generated during their early veg' growth, to produce more biomass, larger leaves and stronger stems. This creates more opportunities for your plants to grow bigger and, with more flowering sites and heavier yields. Basically, more vegetative growth puts your plants in the perfect position for more blossoms.

Garden tip: Metal Halide lamps are only intended for the veg' growth phase. However, you can also utilise MH lights as part of a larger garden with mixed lighting. To produce optimum results, professional growers often use a ratio of 2 HPS: 1 MH throughout flowering.
