Plasma UV Grow-Lights for Horticulture

The flexibility of chemical doses inherent in Ceravision’s plasma lighting technology offers various spectral outputs beneficial for horticulture. Our new UV plasma grow-light provides the vital UV-B and UV-A blocked by greenhouse glass and unavailable from traditional PAR lights. This UV range is crucial for optimal growth, flowering and fruiting and it creates defences against pests and viruses. The UV stresses plants, boosting the production of secondary metabolites that yield essential oils, phenolics, terpenoids and antioxidants. These compounds improve nutritional and medicinal values and are vital for our health and well-being. Industrial hemp grown under our new UV420 grow-light produced significant increases in CBD - see Latest News…19th Sept 2019 "Ground Breaking Results for New Horticulture Light Technology".

ionCORE® Technology

Ceravision's plasma grow-lights offer flexibility in spectral output and with UV are perfect complementary horticulture grow-lights for high value crops including hemp and cannabis.


The UV420 plasma grow-light has the vital UV-B and UV-A blocked by greenhouse glass and missing from PAR grow-lights, to reduce costs, add value and increase yields.


The Environment is at the heart of all we do. We aim to ensure components and processes minimise environmental impacts as we develop HEP plasma lighting to help address food security, water supply and energy efficiency.
