Ceravision’s UV-growlight boosts cannabinoids

Dec 2019: Andrew Fuller of Bridge Farm Group Explains Benefits of Ceravision's UV grow-light...

Mr Andrew Fuller, Technical Director of the Bridge Farm Group, interviewed by Shane Torpey of MIGRO, explains how incorporating Ceravision's UV grow-light for its industrial hemp cultivation boosted cannabinoids by 40%.  Watch the interview here.

Interviewed at Bridge Farm Group’s herb nursery, Andrew explains how he has been experimenting with Ceravision’s UV grow-light to complement the high pressure sodium (HPS) fixtures on its industrial hemp crops.  The results revealed that by applying the UV grow-light at the end of the crop, terpene oil production was boosted by 25% to 40%.  The trials were extended to include other herbs,including rosemary and lavender to improve oil content, flavour and taste. 

In these price competitive markets, Andrew is always looking to differentiate his products and the results with UV reveal significant improvements in taste and flavour that will help give him an edge with supermarket buyers and their discerning customers. 

He uses HPS lamps and is exploring the latest LED fixtures but incorporating them with Ceravision’s high output UV lamps.  The results have been very exciting and Andrew will continue the trials to explore further benefits and determine the best time to apply the UV to optimise the added value for different crops. 

Worldwide research is progressively demonstrating the vital importance of UV in the 280-400nm range from cultivation to consumption.  For most plants this range strengthens root systems, boosts secondary metabolites to improve nutritional and medicinal values, and bolsters resistance to pathogens and pests.  However, this vital UV-A/UV-B spectral range is blocked by greenhouse glass and not delivered in any strength by other grow-lights.  Ceravision’s UV unit tackles this conundrum.

Ceravision’s grow-light has a spectral output concentrated in the high energy 280-550nm range to complement HPS and LED grow-lights and better replicate solar radiation. 

Bridge Farm Group, the European arm of the NASDAQ listed Sundial Group, is the leading producer of ornamental plants, flowers and herbs in the UK.  Using the most innovative techniques in the industry, it sells more than 80 million units per year to retailers and consumers across the globe.  

Shane Torpey is the founder of Partech LED Ltd trading as MIGRO. As a manufacturing engineer, Shane is always keen to explore new ideas and products and to provide independent research and advice on horticulture lighting to help raise awareness and educate industry buyers.  MIGRO has also developed its own LED grow lights.

Ceravision at NIAB Grow Lighting Workshop

Thursday 17th Oct 2019, Ceravision at the NIAB Industry Workshop on Advances in Grow Lighting.....

Ceravision's Dr Stuart Mucklejohn presented a lecture entitled 'All Light is Not the Same' to explain how plants need ​more than PAR light in greenhouse cultivation, they also need the vital UV-A and UV-B to grow to their full potential.   Ceravision also showcased our unique complementary UV420 grow-light at this high profile industry work shop (see details here).  The National Institute of Agricultural Botany (NIAB) is a plant science research company based in Cambridge, UK and organised this event at the Sophi Taylor Conference Centre in Cambridge. Other prominent speakers included: 

  • Erik Runkle of Michigan State University – “Considerations and U.S. perspectives when selecting an LED fixture for greenhouse applications”
  • Dirk Ludolph of LWK Niedersachsen – “LED light for ornamentals – more than fairy lights” 
  • Dr Gareth John of LIA – “Lighting systems and operator safety”.

NIAB is organising this grower-focused event as an essential knowledge exchange workshop, to offer a platform for growers of all protected crops to engage and discuss the latest lighting related products and innovations in horticulture lighting.

Ceravision UV Grow Light Boosts CBD

September 2019: "Ground Breaking Results for New Horticulture Light Technology":

Ceravision Limited, inventor of a new and unique scientific approach to horticulture lighting, today announced the results of trials undertaken over the last six months with a group of leading horticulture businesses.

Results from independently conducted trials with Bridge Farm Group on licenced industrial hemp have demonstrated an increase in yields of cannibinoid oils by up to 40% compared to other lighting solutions.  Trials elsewhere on salad crops have also revealed benefits - faster growth, fewer pesticides and less waste.

Exploiting its innovative plasma light technology, Ceravision’s new and patented approach to horticultural lighting is based on the ability to produce unique light spectra with unparalleled levels of UV-A and UV-B.

This UV spectral range is crucial for indoor cultivation.  UV can benefit plants as it enhances the production of the secondary metabolites that act as ‘sunscreens’ and boost aroma, flavonoids, terpenes, colour, nutritional and medicinal values.  UV can also improve defences against insect and virus attacks and accelerated pollination.

Ceravision’s plasma UV420 grow-light is designed to complement traditional PAR grow-lights.  With a spectrum concentrated from 280 to 550nm, it delivers the UV-A and UV-B not transmitted through greenhouse glass and not available from traditional PAR lights.

Barry Preston, Chief Scientist of Ceravision said: “We are delighted that the proprietary tailored light spectrum of our newly developed UV420 boosts yield, flavour and quality for a range of crops and has the potential to transform horticulture productivity”.

Andrew Fuller, Technical Director of Bridge Farm Group said: “We have tested Ceravision’s new grow-light in the cultivation of industrial hemp and found it to deliver significant benefits compared to other lighting technologies in boosting yield and cannabinoid content.  I believe that Ceravision lighting technology and expertise offers a ground-breaking step forward in horticulture lighting”.

Further Information

Future Applications

Delivering flexible spectral outputs, plasma lighting offers practical economic solutions in horticulture and other applications requiring natural solar levels of UV-A and UV-B, or UV-C for sterilisation.

Plasma Light Technology

Ceravision’s plasma grow-lights, with a spectrum providing UV-B, UV-A and blue herald a new scientific future in horticulture lighting and UV-B is beneficial for humans producing the vitamin D essential for health.

Intellectual Property

Ceravision maintains an extensive Intellectual Property (“IP”) portfolio comprising Patents, Trade Marks and Design Rights.
