Some of the benefits of having plants in your home, home office or business are:

  • Plants exhale oxygen
  • Some indoor plants remove harmful chemicals and gases from the air
  • Plants improve your decor – with color, scent, and multi-textured natural designs
  • Seeing green is good for your brain – increases mental acuity and your feeling of well being (proven)
  • Many plants are food!


Even in smaller kitchens or walled porches, it is easy to grow herbs. There’s  nothing like fresh chopped chives in an omelet, right?


Or fresh basil for pesto sauce?


You can grow more than that if you have the right amount of light.


How high should you hang your grow lights?


Here are some tips.

Stop – what is that?


“In photometry, luminous flux or luminous power is the measure of the perceived power of light. It differs from radiant flux, the measure of the total power of electromagnetic radiation (including infrared, ultraviolet, and visible light), in that luminous flux is adjusted to reflect the varying sensitivity of the human eye to different wavelengths of light. ” – Wikipedia

Kind LED Indoor LED Grow Light K5 Series XL1000 Best LED Grow Light Winner 2017 with Remote and Timer for Plants and Flowers 650W with 12 Band Full Spectrum with UV IR UL Listed | 3 Years of Warranty



This unit solves one of the most common problems that indoor grow LED lights have presented in the past.


Because of historically small footprints, due to small circuit board construction, LED lights have never succeeded in delivering the final harvest weights promised in comparison to their said HPS counterparts.


Uniform lighting in a canopy space is crucial component to your growing results. Kind LED features high quality diodes intensified with secondary optical lenses.


More features:

  • At max PPFD of 720.25 at height of 36′, your garden has the highest available in the market
  • Adjustable spectrum to match vegetative and flowering stages of your plants
  • In addition there is flexibility for specific spectrum control for almost any plant genus in applications such as greenhouse growing and in agriculture operations where crop rotation, or zoning, is practiced
  • All light cycles are programmed and changed from a convenient remote, no bulky fixtures
  • You can mimic the great outdoors like never before seen in indoor growing, simulating dawn the morning and sunset every night, with 8 separately set stages allowing a natural progression of light.  You set these stages to the desired duration and desired spectrum intensities.
  • Each function of the K5 series can be controlled from a convenient remote. It is hard to imagine how people are able  to control spectrum or switch between modes on their lights when they are in the middle of a grow and their light(s) are hanging above a huge canopy of delicate plants without such facility!!! 


Yet, some companies don’t offer this obvious necessity.
