Kind LED K3 Series XL300 300W Full Spectrum LED Grow Lights

The all new K3 XL Series is designed with the hobbyist, home grower in mind, but packs the punch of the perfectly tuned spectrum and intensity commercial growers have come to rely upon from the award-winning K5 Series, providing unmatched quality and yield at harvest.

Taking cues from it’s best-in-class big brother, the NEW K3 XL Series offers the same unprecedented results as the K5 Series with secondary optical lenses and a new expanded perfect 12-band spectrum in an easy to use, plug n' play, seed to harvest fixture. 

The K3 XL300 is perfect for a 2' x 2.5' area footprint

  • Many studies have even show an increase in oil production and quality, closer inter-nodal spacing, and denser fruits and flowers. 
  • Kind LED produces less heat, eliminating the need for additional fans, making them run quieter.
  • Lower light temperatures lead to a much more easily maintained ideal grow environment in which your plants would thrive. 
  • Individual diodes set to a specific color and the 12 band spectrum design that plants need to thrive.

  • Significantly increases flower density and harvest weight with re-calibrated secondary optical lenses that focus light intensity and deliver 200% greater canopy penetration.
  • Optimized diode distribution reduces the hots spots commonly found in LED grow lights, resulting in balanced, rapid growth across the entire footprint.
