The Best 1000 Watt Grow Lights Available

When growing plants indoors, you need a good quality source of full spectrum light for them to flourish. Ignoring this will only mean reduced growth and a disappointing harvest. It is crucial you invest in a reliable grow light for the success of your indoor growing project. Quality is of the essence, especially the level of PAR your grow light produces. It’s even more important than the watts produced. Here are some of the best 1000 watt grow lights to consider.

Kind K5 XL1000 LED Grow Light

If you read my guide to the best LED grow lights for indoor plants, you’ll see my top choice for the best 1000 watt LED grow light is the Kind K5 XL1000. The Kind LED grow light provides a huge footprint with a mix of 320 3 and 5-watt light-emitting diodes. This highly programmable grow light allows digital tuning of the spectrum so you can match it to the exact plant type and growth stage. The Secondary Optical Lenses individually focus and intensify the diode output which magnifies the PAR and increases canopy penetration. My only beef with KIND is they don’t provide PAR data.  While it’s not a perfect measurement, it’s helpful to understand the true coverage of the LED grow kit in question.


  • Runs quiet and cool
  • Extremely energy efficient
  • Sleek design allows it to sit higher above plants
  • Easy setup and programming
  • Convenient handheld remote


  • The power cord is short (only 6ft)
