MH lamps for indoor growing

Metal halide bulbs (MH) emit a cooler light, which is perceived as bluer and favours stem and leaf development. This type of light is also useful for young plants because it prevents them from spiking as they would with another colour spectrum. The result is a production of thicker and more resistant branches that will be better able to support the weight of the flowers.

Characteristics of MH lamps

In addition to growth, metal halide lamps are also useful for the first days after germination, for the same reason as stated in the previous paragraph. This type of lighting is very powerful and provides reliable colour rendering, which makes it particularly suitable for cultivation. For this reason, they are one of the most widely used bulbs by growers all over the world.

The operation of the MH is very simple. They generate light that facilitates the passage of electrons through a combination of gases inside the lamp. MH lamps use a ballast for their operation, which also limits the power they receive so that there are no overload problems.

MH lights work best with compact and bushy plants, as this type of bulb can reinforce the structure of the stems so that they do not take on a very spiky shape that is overcome by the weight of the buds. Indica strains are the preferred choice for this type of light, which does not mean that metal halide bulbs do not work perfectly with other genetics such as Sativas.

Another advantage of MH lights is that they are easy to use. However, one main disadvantage is that they get very hot compared to the new LED or LEC bulbs, which consume much less energy and deliver excellent results just as well. However, in terms of price, MH lights are much cheaper.

Their low price makes MH bulbs the best choice for anyone who wants to get started in indoor plant cultivation without spending a lot of money. The experienced enthusiast can also use this type of bulb to boost the growth of his plants, as well as to set up a supplementary cabinet with plants in germination and/or vegetative growth.

At Experiencia Natural it is possible to find a good selection of metal halide bulbs for plant growth, with blue spectrum and sun-like light.

This is the case of the Agrolite MH grow lamp for growth. This is a lamp designed specifically for growing plants, but it is also suitable for maintaining a growing space for mother plants and cuttings. It does not produce as much heat as flowering lamps and is economical and very easy to install.

On the other hand, there is also the Sunmaster Cool Deluxe MH, a bulb also specially designed for growing at 400W, so it works perfectly in a grow space of 1 square metre. It is also available in a 600W format, ideal for larger crops, such as 1.5 square metres.

MH lights are the best solution for growers looking for extra light for their growing plants. They have a lifespan of approximately 10,000 to 20,000 hours and offer great results at a low cost.
