Increasing the yield by 20% in greenhouses

Our spectral conversion greenhouse coverings can alter the solar spectrum according to the specific needs of different plants, boosting their growth and yield by changing the relative spectral proportions of short- and long-wavelength light.

A polymer film containing the optically active material can be applied to the outside of a greenhouse via a spray. Alternatively, polycarbonate and acrylic sidings can be enhanced directly by infusing the plastic sheeting with Lambda’s active materials.

Lambda’s active molecules can tune the light spectrum for optimum plant growth.

Benefits of Lambda’s active films

  • Increase in biomass yields by 10-20%
  • Beneficial to high value crops including marijuana and berries
  • Lengthening the growing season by 1-2 months
  • Increasing the penetration of diffuse light into the canopy
  • Absorbed UV protects the plastic in of greenhouse sidings from degradation
  • Inexpensive compared to custom LED lighting

Lambda is currently scaling up the production of the active material for small scale test trials at Cranfield University, involving eight greenhouses, some of which will be coated with the active material in paint.

We are seeking further collaborations with materials companies in the AgriTech sector. If you are interested in incorporating our nanocrystals into polytunnel materials, onto greenhouse glass, or wish to get involved in field testing, please let us know.

Lambda is seeking strategically aligned investors who can help us accelerate the development and adoption of our technology. If you would like to discuss then please contact us at
