| On Topic nutrition uptake, and encourage the growth of wastefully long roots. The technical and economic limitations of aeroponic systems, based on mists and sprays, mean they are only suitable for growing leafy greens, such as lettuces, or herbs whereas the unique Airponix fog technology is suitable for www.farmingmonthly.co.uk growing staple food crops including rice, wheat and potatoes. Key to the development of the Airponix system is the company's collaboration with a world-leading developer of piezoelectric drop-on- demand inkjet technology. By employing their printheads to deliver the nutrient-rich fogs to the plants, droplet sizes can be substantially reduced and controlled. So, instead of a mist, an engineered ‘fog' is created to suit the different needs of roots and leaves which play a major role in optimising plant growth rates and yields. The printheads require less energy to operate than other fog making methods, are highly reliable and easy to install or replace under field conditions. Airponix has recently received a £485k convertible loan from Centrica Innovations*. This is allowing Airponix to equip a 1,000 m2 glasshouse in Norfolk with growing units for system development, testing and demonstration. This includes the addition of growth-enhancement techniques, such as electro-culture and RNAi - unique to Airponix - which promise to further increase growth rates and crop yields significantly. Selling this produce should also generate some early income/revenue with the harvest of unique baby potatoes expected from July 2018. Interest is running high in the potential of the Airponix system and the company has recently won a number of high-profile awards including the overall Rushlight Award and the Rushlight Energy Reduction Award in January 2018 and the Bio- technology of the Year Award at the Business Green Technology Awards in December 2017.
