What should you consider when purchasing a plasma grow light?

The size of your grow tent

size of your grow tent

When selecting a plasma grow light to use in your cannabis farm, the size of your grow area is very important in determining how many lamps you will require. The lamps can provide massive coverage, and the light is very uniform. It is advisable to use a growing area that measures 4 feet by 4 feet or more spacious. The grow lights can get very hot. Therefore, using the lamp in a small grow tent can burn your plants. Even with the grow tent that you use, you need to ensure that the ventilation system functions correctly and that there is considerable airflow.

What is your budget

It is easy to ignore a plasma grow light due to its cost. It is one of the most expensive lights for cannabis growth in the market today. However, the value that it provides you may save you a lot more money in the end run. With its ability to last for about 30,000 to 40,000 hours, you will not have to replace the bulbs like other traditional bulbs continually. Additionally, the lamp consumes less power than other conventional grow lights hence can save on your utility bill.

Purpose of your Grow light

Are you using the grow lights as a supplement light, or are you using it alone in your grow room? When you choose to get it as a supplement, it works perfectly with an HID grow light as a boost during the vegetative phase of your cannabis. Since they also produce a full spectrum light, you can as well use them alone on a grow farm. Their light flows uniformly on all the plants in the coverage area of the light.

Why should you use a Plasma Grow Light in your Cannabis Farm?

The quality of light you use in your grow light is one of the top factors that affect the yields of your plants. Plasma light provides your plants with a light spectrum that is similar to that of the sun saving you money that you would have otherwise spent on purchasing an extra light. Additionally, you will get to keep the money that you would pay to replace a bulb such as an HPS grow light since the plasma bulb can last for 30,000 to 40,000 operational hours. During all these hours, you are sure of getting a light that is stronger than a metal halide bulb or an HPS bulb.

Since the plasma light operates through electromagnetic induction, the light it produces allows for a substantial penetration into the canopy of your marijuana plants without any light loss. The light penetrates deep until some of it reaches the growing medium. The amount of energy the lamp consumes to produce the light is a lot less than an HPS bulb. You will also get to save on your utility bills even without having to switch the lights off at every growth stage continually.

The plasma grow lights being new to the market may be a problem. There is not much information on them, and there is much to know about how they operate. Without this information, the price of the lamps can change with time. However, the initial impressions of the lamp have so far been good.

However, plasma lamps have indeed provided hope to the growers since they offer a full spectrum light at a lower cost than that of traditional lights. The above listed grow lights are some of those that home growers have found to be favorable due to their dependability, power, and ease of use.

Before selecting a new product in the market, you must conduct enough research on the features it carries and the benefits it can bring to your farm. Your choice should meet the needs of your farm in both the size of your grow tent and your plant’s requirements. By following this article, you will get all the information you need to make the right purchasing decision.
