There are different types of bulbs for growing cannabis, HM are better for the growth phase and HPS for the flowering stage.

It is important to consider how much light will consume our plantation of cannabis, as a general rule in the growth phase of the marijuana plant are consumed daily around 18 hours of light (6 hours of darkness) and for the flowering phase, they need 12 hours of light (and 12 dark).

When cultivating cannabis is of vital importance light we use. Several types of light and each of them we can provide different benefits. But we must distinguish. The most used are the HPS and HM. We will provide here a little light to see what lies behind these two acronyms. HPS lamps are the sodium vapor, the HM metal halide.

HM Bulbs

M GRO Growth bulb

The type HM (Metal Halide) are the most beneficial for vegetative growth and for germination, maintaining the ‘mothers’ and cloning or reproductive by cuttings.

You will distinguish the HM light bulbs because it is a generally white light with shades of its colors. Only used for the growth phase, we can not use this type of bulbs for the flowering stage.

As a specific bulb plant growth is better in that it develops and we will notice that the buds will be larger. The most used are the 250, 400 or 600 watts.

HPS bulbs

The HPS (the high pressure sodium) bulbs are best for the flowering phase of cannabis. How to distinguish the HPS bulb? The differentiate by its color, the light emitted is orange, although the technology is advancing rapidly and have already found new hues also go through the target. This bulb offers different types of power, there are 150, 250, 400 and 1,000 watts. Prices do not vary much if the power is greater or less, what we do is the result varies considerably depending on which watts are used. A recommendation should be said that less than 250 watts power is not suitable and neither is superior to the 1.000 watts power. These bulbs need about five minutes to go on making the switch to be the most costly expense. The sodium vapor lamps are more efficient because, among other things, reach the entire surface of the plant.
