MetaRail™ Supplemental Pure
UVA + UVB LED Lighting Instrument



AgricUltra specifically designed the UV based MetaRail to stimulate, enhance and elevate the production of secondary metabolites in Cannabis plants (particularly the THC and terpene profiles). This supports producer-inspired plant profiles that lead to premium and unique offerings in the marketplace.

The MetaRail is highly modular and adaptable with three basic power densities. It has customizable lengths from 2 to 8 feet (or longer if required), and will easily integrate into existing grow strategies.

Plastic and glass lens coverings block 95% of UV at its most effective wavelength. The MetaRail uses a quartz crystalline lens which allows for over 85% more UVB to be delivered to the canopy than traditional grow lights.

Multi-Channel Control with Dimming enables growers to develop proprietary light recipes, helping you develop products that are unique to your brand.
