King Plus 600W LED Grow Light is offering your plants a complete spectrum, which includes all the necessary lights, that too in the perfect proportion. The wavelengths your plants get from this grow light are 410nm, 430~440nm, 450~475nm, 620~630nm, 650~670nm, White, IR(730nm). If you want to enjoy good quality cannabis or marijuana, you definitely need to provide a complete full spectrum to your plants, and you are doing that by buying this 600W model.

Power saving capabilities:

Nobody likes to see hikes in the electricity bills. King Plus has taken care of its consumers and built this LED grow light in such a way that it sucks very less energy. Maximum power draw is 120V. You will hardly observe any increment in your electricity bills. Not just that, it has one more thing to impress you, and that is HPS replacing capabilities. 600HPS/MH lamp is what it is capable to replace.

Pleasing coverage area:

At that price segment, you hardly get a 2.5 x 2.5 feet coverage area. This model is providing you a 3 x 3.4 feet coverage area for veg, and 2.4 x 2.7 feet for the bloom. That means you can grow three to four cannabis plants. The canopy penetration of this LED grow light is also good, so you can place your plants a bit closer as well, all parts of your plants will enjoy uniform light.

Along run horse!

Generally, the LED grow lights of this price segment are built for working 16-18 hours a day. The remaining hours is the rest time. Now, let us talk about King Plus 600W LED Grow Light. Although the company says that it I built for serving you for 18 hours in a day, but let me tell you, this model has enough potential to work for 20 hours in a day without any overheating issue.

We were recommended to try it out for 20 hours a day by one other group of grow light testers, and we did the same. The results were good, and no issues troubled us. Salute to the excellent heat dissipation system of King Plus 600W LED Grow Light.

Daisy chaining option available:

The presence of daisy chaining feature means that you can attach several units together. Having issues with a small grow area? Want to push limits? Buy another such unit and connect both with the help of power cord. Now you have double grow area.

The warranty

As you read in the specs that you are getting a 3 years warranty support here. There are just a few things about this warranty, which I find important to explain to you. Till 180 days after the purchase date, the company will do shipping of parts entirely free. After that, you are supposed to pay just the shipping charges, the parts still will be free of cost.

What were the results?

When I hear the word results, I start memorizing school time. Those exam results were horrible. Anyways, keep that aside, let us talk about the results of King Plus 600W LED Grow Light. We grew cannabis and were surprised actually by the aroma!

None of my teammates or I thought that we would be getting such brilliant results by such a cheap LED grow light. You can check the pics HERE!

Hey Amazon, what do you say about King Plus 600W LED Grow Light?

Satisfaction rate is too high there on Amazon. You see, 900+ reviews are there in total, and that shows how much this grow light is rending. Reviewers are not just the beginners. The large-scale and advanced level growers are also deeply impressed by the performance of King Plus 600W LED Grow Light. Not just cannabis or marijuana, but growers got fantastic yields of tomatoes, non-seasonal fruits, and vegetables, pepper, ginger, this, that, etc. 4.5+ stars is the score.

You might be asking if this light is really that awesome, then why were the complainers hopping? Well, first of all, let me tell you, I didn’t come across any uniform complain. All complainers were writing their own Bibles.

One said that it doesn’t come with adjustable ratchet ropes. A couple of others complain that their fan stopped working. One folk broke all the records and was complaining that the light is extra bright! I am laughing right now.

King Plus 600W LED Grow Light review : Cons

Veg and Bloom switch is probably the only feature that is absent here. The company claims that the Veg and Bloom switches block a particular part of the light. They say it is far better to provide all kinds of light to the plants during all the stages of growth. Actually, if we think deeply, then the absence of these switches make the operating a bit easier for those growers, who are new in this field.

If you keep this deficiency aside, then there is no other drawback to explain. I just wanted to give you a tip right now. I read a few cases where one fan stopped working. Suppose you face the same issue, then do get it fixed without wasting time, because if you don’t do that, proper heat dissipation will not take place. The temperature will rise in the grow tent, and your yield will be harmed.

  • Pocket-friendly price tag.
  • Highly powerful and great canopy penetration.
  • Full spectrum support.
  • Excellent heat dissipation system.
  • A big power saver.
  • Brilliant customer reviews and ratings.
  • Daisy chaining feature for expanding grow area.
  • Pleasing coverage area at that price segment.
  • 3 Years limited warranty.
  • 30 Days money back guarantee.
  • No veg and bloom switches present.

King Plus 600W LED Grow Light review : The Verdict

We went across all essential facts, which were compulsory for a buyer to know. You are getting heavy loads of benefits, while on the con side, we just have the absence of Veg and bloom switches. So, it is such a cool deal.

It is truly quite hard to find such perfection with just that much money in the wallet! Generally, two issues arise when you buy a cheap LED grow light. The first issue is limited grow area, and the other is less intensity of light. Although you are getting a good coverage area, but in addition to that, the company has gifted you daisy chaining feature also.

The light intensity is quite high. It can replace a 600W HPS lamp, that much strong it is! Even after providing your plants such powerful light, it is not sucking much energy from the wall. Just 120V, that’s it.

On the basis of brilliant cannabis results, I conclude that you must not miss a chance of buying King Plus 600W LED Grow Light. I highly recommend it to beginners as well as large-scale growers.
