  1. Rated 5 out of 5


    Let me tell you that this small 300 watt LED light rocks. In just two weeks my tiny seedlings grew to 4 inches tall and 11 inches across from tip to tip of the largest leaves. The grorth is incredible with so many shoots coming off of them they look like mini bushes. I have never witnessed just sturdy full growth like this before in just a short time. Compact and dense. I am getting ready to buy the 450 watt light now because I am sold on these Kind LED. They are quite and do not give off that much heat at all. If you were ever in doubt about buying an LED this light will remove all doubt and make you a believer and you will save on your power costs to run them and cool your grow area. If I could give them ten stars I would.

    The 300 watt LED fixture has a great build and is quite effective in a 3×3 to 2×2 area with a 24″ to 36″ elevation above the leaves. Its negatives are that its a bit heavier than other fixtures and draws over 200 watts rather than the expected 160. This may be due to the fans, but otherwise, it works great. I picked mine up used from another grower and will probably be in the market for a larger one soon.

The Kind LED Difference

A Little Kindness Goes A Long Way

  • KINDEST YIELDS – 700 mA Driving Current Creates Up To 200% Deeper Canopy Penetration
  • KINDEST SPECTRUM – Proprietary 12 Band Complete 3 Watt “Perfect Spectrum”
  • KINDEST INTENSITY – Secondary Optical Lens Enhances Diode Efficiency and Magnifies PAR
  • KINDEST QUALITY – Extra Large Heat Sinks, Quiet Fans, Precision Drivers, Superior Craftsmanship

Kind Grows “Kind” Grows

Kind Komparisons:

The Kind K3 LED grow lights are the only 3 Watt grow lights that:

  1. Use a proprietary 12 bandwidth spectrum that runs at 700mA.  Lesser LED grow lights run at 500mA with only a 6 bandwidth spectrum.
  2. Thick, heavy duty 2 CM aluminum circuit boards that dissipate heat much more effectively than other LED lights, making Kind LED lights run more effectively and smoother throughout many, many harvests.
  3. Revolutionary “Secondary Optical Lens” for maximum photosynthetic penetration from plant canopy all the way down to the stem.
  4. These Kind LED lights will match or outperform any other 3 watt LED grow light, including the very expensive HydroGrow LED lights, GUARANTEED!


These Kind LED grow lights use only about half the electricity as HPS lights, and produce much more yield per watt.  Many studies have even show an increase in oil production and quality, closer inter-nodal spacing, and denser fruits and flowers.

Also, because these Kind LED grow lights produce less heat, they do not need to be air-cooled like HPS lights, therefore eliminating the need for additional fans, which also makes them run quieter.

Kind LED vs. other similar LED companies

These 3 Watt Kind LED lights will match or outperform any other similar 3 watt setup that is seen often throughout the web, regardless of price or claims, GUARANTEED!

You may notice that a few different 3 Watt LED lights (DO NOT EVEN CONSIDER SINGLE WATT LED LIGHTS) that look very similar to these, and as far as diode wattage is concerned, they are.  What differentiates Kind LED lights is that they have more bandwidths (12), which equals a much fuller and more complete spectrum (crucial when it comes to photosynthesis).

Another major Kind advantage is the use of the revolutionary “secondary optical lens” which penetrates deep into the plant canopy to facilitate easy rooting and maximize yields.  Kind LED grow lights are the ONLY 3 Watt grow lights that feature a 12 bandwidth full spectrum LED panel, a secondary high intensity optical lens, and 2CM aluminum circuit boards.

Kind to you. Kind to your plants. Kind to the environment.

Grow Kind.
