KIND LED K5 Grow Light Review

For many years, these lights (LEDs), were producing fewer yields when compared to their HPS (high-pressure sodium) counterparts. This is, however, no longer the case. Grow light technology has since advanced significantly and LED grow lights are able to produce yields that are comparable – or even better – than HPS bulbs. LEDs operate at much lower temperatures when compared with HPS bulbs. The end result usually is that they consume less electricity and provide growers with a chance to control the growth cycle in a way you can’t with other technologies. In this article, we give you our Kind LED K5 Grow Light review so you can determine if the XL750 or XL1000 grow lights are something you may want to consider.

The Advantages of LED Grow Lights

California Lightworks SolarSystem 550

Proper lighting is one of the most critical secrets to successful indoor gardening. The main lighting choices on the market today are fluorescents, HID, and LED.  

There are incredible benefits that come with LED lighting  – longer lifespan, lower power bills, healthier plants, less heat, the ability to discourage pests, and more.  The very fact that these bulbs have significant advantages has seen them gradually replace their traditional counterparts. Here are a few benefits of LEDs;

1. They can be used in areas with extreme temperatures:

LED grow lights can be used even in places with extremely high temperatures or low temperatures like winters without changing the quality of light. 

2. They can still run even with low voltage:

One challenge that many growers face is unexpected power fluctuations. This is especially true in storms and other extreme weather conditions. Now, in usual circumstances, traditional lighting systems or bulbs will start to flicker or produce dimmed light whenever there is a power fluctuation.

This is not the case with LED bulbs. These lighting systems will continue burning brightly even when the voltage is affected by a power fluctuation. In fact, with these bulbs, it would be totally impossible to detect a power fluctuation/low power supply.

Overview – KIND LED K5 Grow Light Review

Kind LED is a grow light company that introduced its products to the market a few years ago (2013) and has since won awards year after year. This is also the only grow light company that has been founded by highly experienced growers – a fact that could easily be the reason why their grow lights perform to grower’s expectations and why they have continued to win award after award.

The best thing you can do as an indoor grower – whether you intend to grow cannabis or any other plant – is to choose a grow light that will effectively mimic the spectrum of natural sunlight, or even provide better lighting.

This is exactly what the Kind K5 XL1000 LED Grow Light offers through its 12-band spectrum.

Most LED grow lights on the market today use a 2-6 band spectrum. This is, however, not the case with the Kind K5 XL1000 LED. Not only does the grow light offer a 12-band spectrum that is particularly heavy in the blues and the reds, but it also comes with an IR band and also offers a UV-A band.

The 12-band spectrum feature ensures that plants get all the lighting they need throughout their growth process, the IR band increased yield during flowering, while the UV-A band increases THC production.

All in all, this is a grow or plant light that comes with useful features, most of which are rare in other similarly-priced LEDs.

K5 XL1000‘s Fully customizable spectrum

The K5 XL1000 LED grow light comes with a fully customizable spectrum. This allows the grower to adjust the spectrum to correspond with all growth stages of the plants.

Seedlings – at this stage, the grow light should ideally be tuned to a low spectrum due to the tender or sensitive nature of seedlings. Kind recommends a spectrum range of 15/30/30 once the seeds have broken the surface, and a range of 30/60/60 as soon as the first set of true leaves have emerged.

Clones – clones may be a bit stronger than fresh seedlings, but they still require a gentle spectrum range. Kind recommends a range of 25/45/45 at this stage.

Vegetative – during the vegetative stage, plants tend to utilize high levels of the blue light. Kind recommends a range of 30/60/60, 45/80/80, or 60/100/100 depending on plant type.

Flowering – during the flowering stage, a plant tends to have many complicated biological responsibilities and will now need larger amounts of light. Kind recommends a light range of 100/100/100 at this stage.

Late flowering – during this stage, the plant is likely to have stopped most developmental processes and should be gearing for the ripening stage. Kind recommends dialing the blues lower to a 100/70/100 to stimulate a late summer atmosphere.

K5 XL1000‘s Extra Large Footprint

LEDs, were, for many years, producing fewer yields when compared to their HPS (high-pressure sodium) counterparts. One of the major reasons behind this was a small footprint largely due to a small circuit board construction.

One of the most crucial components to a good harvest lies in a well-lit canopy. K5 XL1000 comes with high-quality diodes that have not only been intensified with groundbreaking secondary optical lenses but have also been spread over an extra-large housing. This has resulted in a significant increase in PAR value and a 200% deep canopy penetration.

The 200% deep canopy penetration means the 2nd and 3rd level canopies receive sufficient light, and the plant is thus able to create more flowering sites further down, which in turn, leads to more yields.

The K5 XL1000 LED grow light features an 8-stage timing function that mimics Mother Nature like never seen before in the industry. This feature takes plants through the natural stages of the sun, namely: the morning sun, the full day sun, the gentle evening sun. Each one of these stages can be controlled to the desired duration and spectrum intensity.

K5 XL1000‘s Ideal Mix of 3 and 5-watt diodes

The K5 XL1000 grow light mixes 3 watt and 5-watt diodes to create the perfect lighting for huge, flourishing and healthy crops. 3-watt diodes emit a gentle light but may not have the ability to penetrate plant copy efficiently. 5-watt diodes have the ability to penetrate plant canopy efficiently, but their light tends to run a bit too hot for the plants liking.

The K5 XL1000 grow light mixes 3-watt and 5-watt diodes to create a grow light that boasts of the best of both worlds – lighting that doesn’t run too hot but holds the capacity to penetrate plant canopy powerfully.

K5 XL1000‘s Pulse Width Modulation Dimming

Just like all K5 grow lights, the XL1000 uses Pulse Width Modulation (PWM) dimming, a dimming method that lessens the brightness of the light without consuming extra energy. This means that the light consumes only the power needed to drive the diodes even when the brightness level is increased.

K5 XL1000‘s Remote Control Feature

All functions of the K5 XL1000 are operated from a convenient handheld remote. The remote is universal which means it can be used on any Kind light.

Kind K5 XL1000 Grow Light is UL Listed

The Kind K5 XL1000 grow light has been UL-listed. All UL-listed products carry a mark to certify that they have been tested by UL and been found to meet most stringent safety standards. UL free products are free from reasonably foreseeable hazards such as electric shock, fire, and related hazards.

Kind K5 XL1000 Grow Light’s Warranty

The K5 XL1000 grow light comes with a complete 3-year factory warranty.

Growing Tips

Recommended Height

According to the K5 XL1000 grow light manual, the light should be positioned above the plant canopy depending on the type of plant being grown. The coverage area will get bigger as the distance between the canopy and the light increases.

Initially, the grow light should be positioned 48 inches above the plant canopy for an acclimation period of 3-7 days. After the acclimation period, the recommended height is 30 – 36 inches above the plant canopy.

Since all plants have different lighting needs, Kind recommends an overall minimum distance of 24 inches from plant canopy.

Additional Tips

LED lights can be a bit harsh on the human eye. As a result, Kind recommends the use of protective eyewear in every setting where their grow lights are in use.

The Kind LED K5 Grow Light Review: The Bottom Line

The UL-listed K5 XL1000 is a good investment whether you are an experienced grower or just a beginner. With this particular grow light, growers can expect excellent harvest and lower power bills. With time, the light should be able to pay for itself.
