The Phyto-Genesis Spectrum

Don’t be fooled by the imitations with their limitations.
Many lighting companies claim to offer UV and IR in their spectrum. The fact of the matter is the vast majority of the grow
lights on the market have completely insignificant UV output.
Go BEYOND PARTM with our Phyto-Genesis spectrum. Our cannabis targeted spectrum with 3.4% UV and 4.9% IR give your plants increased cannabinoid content (+26%) including minor cannabinoids like CBC, CBN, THCv, and Delta 8. Our spectrum also gives you increased yields at more than double the industry standard, with 80 to over 120 grams per square foot.
