Where To Buy

Every plant grower wants the best product to use on their crops, in their home. On the LED grow light market, 1000 watt lights are always the most suitable for a house, with the light being able to impact all of the room.

I have been growing potatoes in my spare room for years, with an old LED grow light; however, I wanted to up the production rates and start selling more of my potatoes.

Recently, I made the decision that I needed to upgrade from my previous 300W grow lights. I looked all over the internet and I came to the decision that the Kind LED K5 XL1000 was the perfect fit for me, although, relatively expensive. I researched a lot on this product and all of its features top the list for me and this product has been very impressive so far. So, let’s get into the many features of this product.

Features of Kind LED K5 XL 1000

Voltage and HID Readings

This feature actually varies according to each and every user. This is due to the fact that the model has differences in growing with LED light and with HPS light. However, I found that once I was used to the differences, I received yields of just fewer than 1000 watts with HPS. On the other hand, I got around 640 watts with LED’s, thus proving the LED’s to be very energy efficient and money saving. However, 630 watts is still a lot of power, so the costs will still be running relatively high. The costs of a kilowatt hour vary depending on the tier it is set in.

Compared to HPS lights, the Kind model saves 30 percent more energy, which comes out to around 415 dollars saved per year. Even if the HPS model is cheaper, eventually, you would have saved your money with the XL1000 and carry on saving, into the thousands if you plan to utilize the light for a long time.

Light Variations/Colours

The Kind LED growth light model uses a 12 band spectrum which includes UV and IR but also reds, whites and blues. When I looked on the market, I noticed that this is the highest amount of spectrums out of all other LED growth products. The reason for the colour changes is to give the plant, vegetable or in my case, potatoes, the same light spectrums as the Sun would. Although, the Sun uses more green and yellow light, but there is a reason. This is because your crops and plants do not need much of this light, so once again, the Kind LED K5 XL1000 is saving you money on your electricity bill.

It may seem weird to you that the spectrum actually works just like the Sun, but I can assure you it works nearly the same, but in my opinion better. The LED lights utilize more red and, especially, blue light, which actually makes the growing process faster though, robust growth. With plants such as flowers, HPS lights grow the flower quicker; nevertheless, the LED light grows vegetables quicker than a metal halide light.

After all of this being said, higher quality buds are always produced with LED lights, rather than HPS bulbs. THC production is also increased with the use of ultraviolet light.

I personally found the manual fantastic, as it showed me the ratios for all common plant types, even potatoes. The ratio works by using the controller to turn up and down the intensity of the three colours: white, blue and red. At some points of the growing process, I would turn down the intensity to save my money, and I must say, I saved quite a lot.

On the manual there were instructions on the intensity needed for seeds, vegetables and flowers. For example, seeds would need only 15 percent red intensity and the white and blue needed 30 percent. For flowers, all three were recommended to be set at full power, until late in the growing stage.

Par and Coverage Area

In this section I will talk about PAR and the coverage area of the product, starting with the coverage area.

When looking into the product, before purchase, I found out that the coverage area was likely to be about 5 by 5 feet. For me, this is about right, and what I, myself, required for my batch of potatoes. This is most likely because potatoes generally only need a small amount of light. If you are looking to grow a plant such as cannabis (that needs a lot of light) the amount of coverage area would be around 4 foot by 4 foot – from my testing and researching.

I have to comment on the canopy penetration and how I underestimated it. My previous light penetrated very well, and from what I read, HPS lights penetrated far better than LED lights. This was my only worry, yet, I was extremely impressed, even though it did not penetrate as much as my previous light and it was good enough for potatoes.

Overall, the coverage area is very good for me, but it will vary per person. If you need excessively great penetration, you would have to hang the light lower, resulting in a reduced coverage area. On the other hand, if you have a 3 by 3 foot tent, the light will be able to cover all the plants, easily.

Moving onto PAR. Unfortunately, the LED light does not contain a PAR rating. This is Performance Appearance Rating. I believe that, the product is better off without a PAR as a PAR usually misleads customers, even me. Although, it would have been interesting comparing this product’s PAR to other products in the same market.

Types of LED and Different Configurations

The XL1000 model consists of LEDs, 3 watt diodes and 5 watt diodes. There are 320 diodes, both 3 watt diodes and 5 watt diodes included. 5 watt diodes are useful for penetrating deeper into the canopy, moreover, producing more heat. On the other side of the spectrum, 3 watt diodes produce less heat and use less amounts of power.

The variation of two diodes provides the model with the perfect balance, more so than other LED models on the market at the moment. The balance also protects your money by using both cooler (cheaper) and hotter (more expensive) diodes. How big of an advantage, I hear you ask? Well, Kind has not released information regarding how many of each diode they use, which is quite suspects, to me. As the wattage is 630 watts, surely, most of the lights are 3W, so are they hiding that they don’t really use the perfect balance? We’ll never know the answer, however, the lights are perfect for me so I wouldn’t worry. They do say that each diode is equipped with a lens, improving the intensity and penetration onto the crop.

The diodes are expected to last over 50,000 hours and none of mine have failed so far and in my research, I could not deduce any myself. This is surprising considering the diodes aren’t actually name branded.

How Much Heat?

In my experience with the Kind product, the heat produced is less than I expected, considering how many watts the product releases. During my research, I found a lot of people that thought that the product would produce practically no heat, which I thought was weird.

The exact amount of heat it gives off, it was 2100 BTU, which is considerably less that an HPS light at around 3400 BTU. For, me the heat was not an issue as I live in Britain, where it is quite cold at all times. If it gets too cold, I can simply just bring a heater in, so it would probably be suitable for all countries and areas.

Controlled Operation

The XL1000 comes with a controller, which you can use to do all sort of useful things. I was surprised to find out that the controller can control over 100 of the lights, individually. When researching, I could not find another LED growth light on the market that included a remote control, this feature is pretty astonishing.

Because of this remote, I have not had to lean over my potatoes, potentially breaking them. With my HPS, I damaged a fair few of my potatoes, but with this unique concept, I do not have this problem.

Earlier I mentioned the ability to change the colour intensity with the product, guess what? This can be controlled simply by the Kind controller. Referring from earlier, you can control the blue, white, and red intensity.

One extremely smart feature is called Mother Nature. Basically, what it does is make the light dull in the morning and bright at around noon, just like the Sun does.

I did have a slight worry about the reading on the

XL1000 that is red, on the control panel affecting the plants unnecessarily when it is their dark hour. However, I read up on the Kind website and it turns out the amount of light sent from the reading cannot affect the growth of the plant.

The Size

The dimensions of the Kind XL1000 are 20 by 26 by 3.5 inches, which weighs a hefty 36 pounds. This is genuinely an acceptable weight compared to other similar products.

What Benefits Come with Buying the Tangible Product?

With the actually grow light comes a 6 foot 110 volt power cord and heavy duty hangers. The lead is quite a small downfall because it is just a little too small, and it would be hard to use in a place far away from a plug. To combat this, you can simply buy a longer extension cord, which can be quite a nuisance. This is quite poor and I had to pick up an extension cord from a nearby shop.

A pretty long warranty, 3 years to be exact, is promised to buyers, which allows them to have anything that is broken to get fixed (this hasn’t happened to me yet). However, there are some disadvantages, with there being a reliance on you to pay the cost for delivery after the first 90 days. When shipping back (after being fixed) Kind will cover the cost, but only up to 50 dollars.

The best part about is that there is a 90-day money back guarantee, and from what I have seen, no other company similar to Kind does the same.

The Reliability of Kind

The trust in Kind is very high, with the company retailing in stores all over the world, specifically in the United States of America. I looked on their website and they have fast contact options, such as email and phone. This shows that they think about their customers and they care for each of them.

They have earned the award for the bestselling glow light an astonishing 4 years in a row. This may not seem like a great achievement, but the grow light market has grown a lot in these years. This also shows they are the most well-known brand in the market.

The Looks

Personally, I believe the Kind XL1000 is quite beautiful, with its colourful lights and patterned LED’s on the bottom. Everything is designed, from the case to the specifications in a modernised fashion. The looks aren’t the main part, or even an important part at all, but seeing a pure black design is never exciting.

The XL1000, in my opinion, is the best grow light on the entire market. The past several years show that Kind has been the top grow light producer in the last 4 years – officially. Kind’s best product is the XL1000, so this shows that they clearly have the bestselling product on the entire market.

I believe the positives vastly outweigh the negatives, because the negatives don’t really affect somebody. For example, a short power cord only affects a consumer a small amount, as all they have to do is buy an extension cord. The only other negative that is serious is the low coverage area; however, for me it is not a problem. If you really needed more coverage area, theoretically, you could purchase 2. This is different in all situations, for each person. Everyone should do their research before buying this product.

There are many positives that set this grow light at the top of the list for me. The first is the remote control accessory, unlike any other similar product on the market; the control can customize over 100 individual LEDs. There are lots of intensities and spectrums to choose from, such as red, blue and white. These can all be put in different intensities to save money and energy. The intensity can be selected by the remote control, which I mentioned before. There are many other features, such as the Mother Nature feature, which involves it being a dull light in the morning, the brightest at noon and in the afternoon it is dull again.

Overall, I must say that this product is truly fantastic, from the bottom of my heart. I would recommend this over the next best alternatives such as the Black Dog Phytomax-2 600 and other products in the same price range.
