MH Metal Halide Grow Lights

What is a Metal Halide Lamp?

Metal Halide (MH) grow lights, also called halogen mercury lights, are HID lights (High Intensity Discharge). In these discharge lights, light is produced via an electric arc between electrodes.

MH lights (metal halide) need to be used alongside a ballast of the same power and a reflector used to redirect light to your plants.

Why Should I use a Metal Halide for Plant Growth

MH lights use a light spectrum similar to spring sun. It’s ideal for saplings right up until the end of the growth period. If you use MH lights your plants will grow strong and produce short internodes, ready to flower in no time at all.

The best way to use HID lights is to use a MH light during the growth period an a HPS light for the bloom stage – this is the highest performing and yielding method.

What Metal Halide Light to Use?

During the growth period, cannabis plants don’t need as much light as they do during the flowering period. If you want to save money, you can use a less potent bulb and ballast. For example, you can combine the following:

250w MH during growth with 400w HPS during flowering.
400w MH during growth with 600w HPS during flowering.

MH Grow Lights for Grow Tents

80x80 cm Grow Tent – 250w MH
100x100 cm Grow Tent – 400w MH
120x120 cm Grow Tent – 600w MH
150x150 cm Grow Tent – 1000w MH

MH grow lights are best for using during the growth period and for clones and saplings. They have a lower lifespan than HPS lights, around 20000 hours. After about 9 months of continuous use you should replace them.
