Picking the Best Grow Lights for Marijuana

marijuana grow lights

Every marijuana grower knows that the choice for light is very important for a grow room.  This is essential for the plant’s growth just like how important the CO2 and water is.

For this article, we will talk about the different LED grow lights that you can consider for your marijuana grow room.

A lot of newbie marijuana growers always have the question on their mind on which LED light to use. Growers should understand that adding an LED light is a great decision and the results will always be rewarding especially if you end up using the one that has a high performance and the company who manufactured it is very reliable.

So for the lights that you can use for your marijuana grow room, here is some information about them:

HID (High Intensity Discharge) Lighting

This particular lighting is the most efficient way to convert electricity to light that is widely available to every consumer. You should also understand that there are two types of HID lighting:

  • Metal Halide (MH) – These metal halide bulbs help produce an abundance of lighting in the blue spectrum. The color of this light promotes ideally for the growth of cannabis plant and can be excellent for that green leafy growth and will ensure that the plant remains compact.

If there is no natural sunlight available, then this is the best alternative for an artificial light source. The average lifespan for this light is at around 10,000 accumulative hours. Even beyond the accumulative number of hours, the bulb will still light up but then that usage is not worth your wait until it finally burns out.

If you compare their brightness per unit of energy consumed, this light source can produce up to 125 lumens per watt compared to the 39 lumens per watt being produced by fluorescent lights and 18 lumens per watt for the standard incandescent bulbs.

  • High Pressure Sodium (HPS) – This light source emits an orange-red glow. It helps trigger hormones in the cannabis plants to increase its budding/flowering. This is best used as a secondary or supplementary lighting in conjunction with the natural sunlight. You can tell that this is much recommended for a greenhouse.

Apart from being a great flowering light, it can be a great economical choice. The lifespan of this light lasts twice than that of the metal halide but after 18,000 hours of use will cause it to consume more electricity and will produce lesser light. These bulbs are also very efficient and it can produce up to 140 lumens per watt. The only disadvantage that this light has is its deficiency on the blue spectrum.

If a grower will use an HPS bulb for a young cannabis plant, he will see an impressive vertical growth. Most cannabis plants will grow up thin lanky and you will prune your cannabis plant back before it even grows into the light fixture.

So the next time you set up a grow room for your marijuana plant, be sure to always be considerate about the type of grow light that you will use.
