Kind LED K3 Series XL300 Full-Spectrum Indoor LED Grow Light

The all new K3 Series XL300 by Kind LED 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 K3 Series XL300 achieve the same unprecedented results as the K5 Series, but on a considerably cheaper price. 

The XL300 is an easy to use full-spectrum LED grow light designed especially for grow tents and smaller-scale home growing. Providing coverage for 5 square feet, this Kind LED Grow light supports all phases of the growing cycle, whether used for small-scale home growing or in a grow tent. The K3 XL300 has the growing power of 300 Watts of a high-pressure sodium (HPS) or metal halide (MH) bulb, with a PAR Value of 776 μMol/m2/s, while only using 210 watts of power. This commercial indoor LED lighting system is perfect for a single light in a tent or several hundred lights in a large commercial operation. 

Essential Factors that Make Kind K3 Series XL300 Highly Innovative

  • Amplified quality and potency, with newly enhanced UV diodes to increase terpene and flavor profiles.
  • The K3 series significantly increase 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 hot spots commonly found in LED grow lights, resulting in balanced, rapid growth across the entire footprint.
  • The XL300 pulls from the wall 40% less electricity to operate without sacrificing yield, while increasing harvest quality. Cutting your power bill in half guarantees a return on the cost of the fixture in less than a year of growing.
  • 90 x 3 watt diodes with 50,000+ Hours Lifespan that lasts 5x longer than traditional grow light bulbs, which means you have less maintenance and more growing without a drop in quality of light.
  • Lifetime professional grow support so you never have to grow alone.
