What is plasma grow light? How do they work?

Plasma grow lights have only been around for a few years, but they are quickly becoming popular among gardeners and growers. While the technology is still new and less tested than other options available, plasma grow lights offer several benefits that make them a tempting choice for those looking to invest in new grow lighting technology.

The history of plasma grow lights begins with plasma TVs. Plasma TVs use a plasma display panel (PDP) to create the image on the screen. A plasma display panel comprises millions of tiny cells filled with gas. When an electrical current is applied, the cell's gas ionizes, creating plasma. This plasma then emits light, which creates the image on the TV screen.

It was this technology that led to the development of plasma grow lights. Scientists realized that using a plasma display panel as a light source could create a grow light that emitted a broader spectrum than traditional fluorescent lights. They also found that plasma lights used less energy and had longer lifespans than traditional grow lights.

The first plasma grow light was developed in 2007 by the Japanese company Plasmacluster Technology Incorporated. Since then, many other companies have developed their plasma grow lights, and the technology continues to evolve and improve. Today, plasma grow lights are used by many growers and horticulturalists worldwide, offering several benefits for their businesses and plants.

The benefits of plasma grow lights

There are several benefits to plasma grow lights that make them an attractive choice for gardeners and growers. These benefits include:

Broader light spectrum: Plasma grow lights emit a broader spectrum of light than traditional grow lights, including ultraviolet (UV) and infrared (IR) light. This makes plasma grow lights ideal for plants that need UV or IR light to thrive. Also, plasma lights emit more blue light than other grow lights, which is ideal for plant growth.

Energy efficiency: Plasma grow lights are highly efficient, using less energy than traditional grow lights while emitting the same light output. This means plasma grow lights are both cost-effective and environmentally friendly, helping you save money on your energy bills and reduce your carbon footprint.

Longer lifespan: Plasma grow lights typically have a longer lifespan than other grow lights, lasting up to 10 years or more without needing to be replaced. This can help you save money in the long run on replacements and maintenance while also reducing waste from old bulbs.

Deeper light penetration: Because plasma grow lights emit more blue and UV light, they can penetrate deeper into your plants, reaching the leaves and stems that traditional grow lights might not reach. This helps you achieve healthy, robust growth throughout your plant, giving you bigger yields in less time.

Cost: Plasma grow lights tend to be more expensive than other grow lights, due to their newer and less tested technology.

Disadvantages of plasma grow lights

While plasma grow lights offer many benefits for gardeners and growers, they also have some downsides that must be considered. These downsides include the following:

New technology: Plasma grow lights are still relatively new, so they have not been extensively tested or even fully understood by scientists. This can make plasma lights risky and lead to unexpected problems or results. Also, plasma lights may not be as reliable or effective as traditional grow lights, particularly if used incorrectly.

Heat output: Plasma grow lights give off a lot of heat, which can cause problems for plants that are not equipped to handle it. In particular, plasma grow lights can overheat your plants and lead to burn damage or even plant death. This can require additional monitoring and maintenance to keep your plants safe.

High Cost: As mentioned above, plasma grow lights are more expensive than other options due to their newer technology. This can make plasma grow lights a significant investment upfront, which may be difficult for some growers. Also, plasma grow lights may not offer the same return on investment as other grow lights, potentially resulting in a loss for growers.

Heat output: Plasma grow lights can produce a lot of heat, which might require you to invest in extra cooling equipment to keep your plants from overheating. This can increase overall costs and maintenance requirements, making plasma grow lights less attractive to budget-conscious gardeners.

Lumens output: Compared to other grow lights, plasma grow lights tend to have lower output. This means that plasma lights may be less effective at keeping your plants healthy and growing well if you need more light for your plants.
