Voted 2022's “Best True Spectrum” Grow Light, Trustpilot’s #1 Rated LED Grow Light, 4x Gear of the Year “Best of” Winner - The KIND LED X- Series!
Unlike other grow lights that rely on white and far-red diodes to grow plants, Kind LED delivers perfected photon distribution with optimized intensity at every wavelength to deliver a complete, targeted full spectrum to your developing plants, resulting in unparalleled weight and quality at harvest. By not neglecting blue and oversupplying white, Kind’s lights produce faster, bushier, and tighter growth, paving the way for packed, dense flowers with the highest terpenes and quality. X-Series lights include a separate, dimmable UV/IR channel that super charges your harvests by allowing you to provide trichome inducing wavelengths at the right time and at the right intensity. Kind LED Grow Lights was founded by career California growers, are well known for their exceptional grow support and customer service, and have been the choice for professional growers since 2012.
The X420 is one of the best LEDs you can expose your plants to. The new X Series from KIND use top-bin Osram & Phillips diodes to product a targeted full-sptrum light along with UV and IR to boost your plants during flowering stages.

Features & Benefits of the X420 LED Grow Light
The KIND X420 uses Full spectrum diodes used by white light LED companies were originally designed for home and office use. Kind’s Targeted Full Spectrum is specifically engineered for plants to maximize harvest weight and plant quality. Our spectrum is the result of hundreds of thousands of hours of field testing in Northern California’s medicinal plant industry.
- FASTER, HEALTHIER GROWTH - 2x Increased PPF
- GROW MORE FOR LESS - 50% Greater Efficiency
- GREATER RETURNS FROM YOUR GROW ROOM - 3.5x Improved Light Distribution
- UNLOCK YOUR PLANTS’ FULL POTENTIAL - Independent, Precision UV/IR Control
- SAFE. SIMPLE. EASY. - Lightweight, Low-Profile, Superior Design
Yields Maximized with Precision UV/IR Control
UV and IR are essential for increasing flower development and ramping up secondary metabolite production which increases both potency and terpenes. Since this added spectrum is only needed in the late stages of flowering, we’ve placed it on a separately controlled channel so you can decide when you use it, eliminating wasted energy and avoiding unwanted stretching during the earlier stages of plant growth.


KIND Targeted Full Spectrum During Veg and Bloom


MAXIMUM HEIGHT - MINIMUM HEAT
The New X Series' external driver mount offers a 60% reduction in light height (more grow space) and a 25% reduction in heat output
LIGHT EFFICACY ≠ PLANT EFFICACY
Efficacy measures a light’s capacity for turning electrical energy into photons but does NOT measure the number of photons that are usable to plants. Most high efficacy diodes are designed for home/office (not horticulture), and while they produce a lot of visible light, much of that light is not used by the plant and wasted as heat energy. Most white diodes are cheaper to produce and measure high in efficacy but use a spectrum that creates wasted light for plants.
TARGETED FULL SPECTRUM VS STANDARD FULL SPECTRUM
Full spectrum diodes used by white light LED companies were originally designed for home and office use. Kind’s Targeted Full Spectrum is specifically engineered for plants to maximize harvest weight and plant quality. Our spectrum is the result of hundreds of thousands of hours of field testing in Northern California’s medicinal plant industry.
