How Does a Grow Light Work?

Grow lights provide the spectral wavelengths needed by plants to support their growth and production. Plants convert sunlight energy to energy they can use, through the chemical process of photosynthesis. Grow lights mimic this effect. Short, blue wavelengths are found in the warmer temperature range of light, whereas long, red wavelengths are on the cooler. Plants use various temperatures of light to promote stages of their growth. Early growth and vegetation need more blue, while blooming and producing plants need more red.

What are Plasma Grow Lights?

First off, let’s start out by being aware that Plasma grow-lights are an investment. These are high tech lights that are still very new to the industry and a debate still exists if these are the grow lights of the future- or simply an alternative lighting choice that falls amongst those that are already available. No matter where your opinion may fall, these are an effective choice in the current market with great results being seen in a variety of contexts.

Plasma lights have a full spectrum to support all plant growth stages. They claim to mimic natural sunlight more than any comparable lighting source in the current market. They work using Light Emitting Plasma (LEP) bulbs and are compared to High-Pressure Sodium (HPS) bulbs. The difference is that they are a solid state light source and do not require an electrode for gas ignition.

Why Choose a Plasma Grow Light?

There is no doubt that these are efficient lights as seen by many studies done with side by side comparisons in controlled environments. They provide an excellent full range of light spectrum to support plants from seedling to production and are considered bright, cool burning sources. They also claim to draw a significantly lower amount of power when in use, making them a more environmentally friendly choice as well.

Concerns about Plasma Grow Lights

As a new item, there aren’t decades of use to back the claims despite initial impressions being favorable. They also are so new to the industry and have a pretty hefty price tag. Although, in the last few years, we have seen it decrease in price as it gains sales and popularity. There is no doubt that it is an effective light.But, the question still remains in the longevity of its use. If it is as favorable as other, well-known grow lights and if it really is a light to replace all others that have come before it.

How to Choose the Best Plasma Light for Your Plants

As with any time you choose a product, you should well research the benefits and features associated with it. This is especially true when dealing with a fairly new product that is gaining support in the consumer market. Detailed Plasma Grow Light reviews are few and far between, so you should ask yourself a few questions leading up to your purchase to narrow down your choices.

How much space do you need to cover?

The strength and brightness of these lights allow for a decent size footprint, which makes them more effective than earlier counterparts. Because of this, they also need to be mounted higher than what you might be used to. So it is essential that you have enough space in order to keep your plants from burning.

What stages of plant development do you need to support?

Since Plasma lights are considered a full spectrum choice, if you are wanting to support specific stages of growth, this may be considered overkill. This is especially true if you are in any sort of budget.

Do you have proper ventilation and space?

Lights generate heat and need enough room for proper ventilation. As mentioned, they also need height for proper mounting. Be sure to closely look at dimension and specs of the light and know your own space measurements before committing to a purchase.

What plants do you plan on growing?

Not all plants crave the same lighting, as others, in their various stages of growth. This is especially true of more tropical species. So, it is definitely worth your while to have researched your plants prior to buying to ensure you aren’t getting anything unnecessary.
