LEDs for Superior Chemical Expressions

IMPORTANT: Valoya sells LED grow lights for the cultivation of medical plants (e.g. Cannabis sativa) only in those countries where it is legal to do so and only to those customers who are in possession of appropriate cultivation licences, as defined by local laws.


Cutting Edge LED Technology for Your Grow

Superior quality light spectra inside high-performance LED luminaires can expedite the growth cycle and produce plants with increased flower dry weight and a higher concentration of Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD), and other secondary metabolites.

Valoya’s spectra have gone through years of independent testing against traditional lighting technologies such as High Pressure Sodium (HPS) and competitor products. As a result, the light spectrum we developed for medical plants is one of the widest on the market and includes wavelengths beyond the PAR area (400-700 nm), such as far-red and UV-A. Thanks to this, plants develop a compact phenotype and produce more secondary metabolites and terpenes. Furthermore, the addition of shorter wavelengths such as deep blue and UV-A reduce the chances of pest development.

Spectrum Quality vs. High Light Intensity

Cannabis benefits from high light intensities as well as a finely tuned spectrum. The brighter the light, the greater the yields. However, after a certain PPF value, the yield increases slow down and do not justify the energy needed nor the number of LED fixtures. This is why a carefully developed and cannabis-optimized spectrum is a better guarantee of success. It will help you produce plants with industry-leading secondary metabolite expressions at the optimal level of energy invested.

Valoya has tested more than 60 LED spectra over the past 10+ years to find the highest quality light for plant cultivation. Solray is a wide, optimized sunlight spectrum that spans the wavelengths from UV-A to far red making it one of the widest spectra available. Additionally, it boasts the highest CRI value in the industry (95/100), making it the most natural-looking horticultural LED light available.

DLI Calculator

Calculate the total amount of light your canopy receives in a single day (DLI – Daily Light Integral) by providing the PPFD value and the number of hours during which the canopy is illuminated.

Alternatively, you can calculate the PPFD or the photoperiod by providing the other two values.

Based on

Valoya has been committed to research since its founding and has thus far conducted 600+ trials on 300+ plant species/varieties, including Cannabis sativa. In addition, to find the optimal light for plant cultivation, we have tested more than 60 LED spectra.

Our biologist, Ms. Stiina Kotiranta has co-authored the first scientific paper dealing with a comparison of effects of HPS vs. LED lighting for cannabis:

We understand that fast bench turns with increased yields of secondary metabolite-packed plants are what our customers need consistently, cycle after cycle. Our team of biologists will track your yields’ progress and advise accordingly to help you reach these goals.

Valoya has been found through both own and 3rd party research to create compact cannabis plants with a higher secondary metabolite accumulation than with generic white LEDs or HPS.
