What to look for when buying Indoor Grow Lights

There is no denying that choosing the right indoor grow light could be challenging for some people. However, that should not mean that this is an impossible task. Various aspects go into the selection process, and understanding such elements ensures that you make logical decisions.

Here are the few things to keep in mind.

i. LED vs Fluorescent

There is no doubt that lighting matters the most in hydroponic rooms, and investing in the right light is vital. Remember, this light will last for about 10 to 12 hours daily. That means choosing the wrong one could jeopardize the quality of your yield. You will have to choose between LED and fluorescent lights.

LED lights are some of the most reliable and popular lights you can consider. They emit wavelengths akin to the natural daytime spectrum. Besides, you can adjust them depending on the plants you have. What is more, they come with cooling systems that enhance their efficiency. It will be fair to mention that LED lights are directional. However, their initial cost could be relatively high.

On the other hand, fluorescent lights depend on converting electrical energy to produce ultraviolet wavelengths. You could get them as either CFLs or fluorescent tubes. Usually, most people appreciate this form of light because of how affordable it is. They also tend to be more versatile and attractive.

If you were to choose between the two, LED would have the edge over fluorescent bulbs. That is because of their reliability and the wavelength produced.

ii. Light Intensity

Take the time to understand the right light intensity for your plants. This way, choosing suitable light intensity will barely be an issue. In most cases, your focus will have to be on enhanced power. The more akin it is to natural light intensity, the better it will be for you.

The light intensity will often vary with the stage of growth. While the light should be bright, ensure that it is not direct to sunlight. This light intensity should be around 40% of the midday sun.

Ideally, you should focus on devices that provide a more extensive light footprint. That is because they assure you of reaching many plants comfortably.

iii. Spectrum

The spectrum of light chosen will often determine how fast the plants will grow. It will also play a significant role in photosynthesis and ensuring that the plants thrive. Mostly, the choice will be between double and full-spectrum lighting.

Full-spectrum is a form of lighting whose wavelength is almost similar to what the natural sunlight produces. Typically, they are a blend of IR, UV, and visible light bands. That they produce different colors means that you will be sure of varying roles and values.

With this, you will be sure of your plants growing much faster and even thriving. Both blooming and fruiting will be effortless.

In contrast, indoor grow lights without full-spectrum will barely be as effective. For that reason, the competency of full-spectrum options makes them the best.

iv. Durability

There is no denying that you will often look forward to enhanced durability, as it determines the value for money you get. This durability depends on the construction and materials used on your chosen device. As long as you opt for sturdy structures and premium materials, you will be sure of the ultimate satisfaction. For instance, steel will last longer than plastic devices.

While at it, it would be best for you to opt for long-lasting LED, as they assure you of cutting-edge solutions. Check how long the chosen LED will last. The lifespan is usually in light hours, and things will be better if this period is much longer.

As you look at the quality of the construction, confirm whether it is what you are paying for. Will excessive heat destroy this device? Will it be susceptible to corrosion and moisture? If the answers are no, you are good to go.

v. Color

The color produced by the indoor grow lights will always matter. The perfect colors for your indoor garden will always be red and blue.

Usually, blue comes in handy in enhancing chlorophyll absorption and photosynthesis. You will also rely on UV for much faster growth. All this is to the 400 to 520-nanometer range it provides during illumination. Did you know that blue is readily absorbable in the leaves?

In contrast, red light produces between 610 and 720-nanometer spectrum range. This spectrum makes it ideal for blooming, flowering, and fruiting. Adding red will always come in handy in making the leaves and the plant much stronger.

Most experts will recommend that you consider a blend of red and blue. If your chosen grow light has this mix, you will have no reason to worry. With this, your yield will be unrivaled.

vi. Ease of Use

Nothing could be as significant in your grow light as its ease of use. Usually, everyone will want a product that they can use without too much hassle, and you need not be an exception.

Now will be the right time for you to pay attention to whether the device has an auto timer. Auto timers are vital for enhancing convenience, as they allow you to set when the device can go on or off. Whether you are there or not, your grow light will go out or on if set accordingly. Check the intervals for this timer. Such intervals will often be between 3 and 12 hours.

Further, confirm how easy it will be to access the control buttons. There is no denying that easier access means you will barely have a hard time in the long run. For instance, separate Veg and Bloom buttons come in handy in optimizing the use of energy. All in all, let your buttons be readily accessible.

Additionally, you might want to consider the use of remote controls. Having a remote control feature implies that you will not struggle with your device whenever you want to adjust settings or switch it on. Such devices could be your focus.

Most people will appreciate programmable devices, as this is what provides them with the convenience they deserve. As long as you can set schedules, it will be much easier to attain the flexibility you envision. A device with an incredible memory will always come in handy for you.

vii. Size and Shape

You can barely overlook the considerable role that the size and shape of indoor grow lights tend to play. Mostly, bigger grow lights will be vital for those who want increased illumination surface areas. Besides, bigger devices have proven to provide much more intensity. That is all you need for the faster growth of your plants.

As if that is not enough, the size and design of your indoor grow light will determine portability. Much smaller and lightweight options will ensure that you have a much easier time carrying them.

While at it, pay attention to the shape of your grow lamp. Does this shape allow light to reach most of the plants? If yes, this will be your ultimate choice. This lamp could be a panel or in the form of bulbs. Whichever you choose, ensure that it provides you with the maximum value for your money.

Both the shape and the size should assure you of easier adjustability. If only you would get a relatively light device with a swivel, you will never regret it.

viii. Photosynthetically Active Radiation (PAR)

This is a type of light spectrum whose role in photosynthesis is almost impossible to overstate. Its wavelength should lie between 380 and 720 nm. Higher PAR values imply that the light range reaching the plant is more diverse and reliable for enhancing your crop yield. In short, it determines the light footprint left by a grow light

ix. Surface Area covered

While the surface area covered by the grow light will often depend on the shape and size of your light, it could be independent. Most often, you will need a device that can shine enough light throughout the hydroponic. For this reason, you must be sure of the amount of light provided by the chosen grow light.

Take the time to focus on lights that provide extensive coverage. This way, no crop will end up missing out on enough light. It is through this that you will be sure of not only enhanced photosynthesis but also growth rates in the long run.

x. Cost

There is no denying that people will always pay more attention to their budgets. Unless the cost of a product is within their budget, it will be hard for them to settle on it. However, it will always be vital for you to focus on the quality of grow lights instead of the cost. What matters is the value for money that you get at the end of the day.

While affordability matters, cheap should not. If you are looking for the best grow lights for indoor plants, you might need to sacrifice a little more money. However, you could consider a product that is relatively less costly to maintain. This way, you avoid too many replacement expenses and repair costs.

Conclusion


From enhancing plant growth and optimal temperature in the hydroponic to better crop yields, you cannot dismiss the significance of grow lights. The catch is that you get a reliable option that can last you for a relatively long time. While the selection process is a challenge, you do not have to give up. Fortunately, the insights provided above could be your lighthouse, guiding you through the process.
