At LettUs Grow™ we are proud to be a mission-driven commercial company. Our goal is to have a net positive social and environmental impact, whilst simultaneously building a growing, commercially sustainable company. We have distilled this mission down to the following simple statement:
Forecasts from the Food & Agriculture organisation of the UN (FAO) predict that humanity must double food production to feed 9 billion people by 2050. All with 25% less farmland, degraded topsoil, and an unstable climate. Currently, the majority of our “fresh” produce is imported out of season, often travelling hundreds of miles to reach our plates, at the expense of our planet and palate. We believe that something must change.
In recent years, urban agriculture companies have attempted to address these issues with localised production methods such as vertical farming, near to and within cities. This shortens the supply chain to provide fresher produce with a reduced environmental impact. However, vertical farmers worldwide are struggling to reach cost parity with traditional open-field agriculture due to high set-up and operational costs. To service the mass market, vertical farming must become either more efficient, or more profitable.
Significant advances have been made through energy efficient LED lighting and data-driven farm management, but moisture delivery, one of the key requirements for plant growth, has not received such attention. Currently, in conventional hydroponic systems, roots are submerged and saturated in a solution of water and nutrients. This restricts the access of roots to oxygen, limiting plant growth rate, and therefore yield.
Vertical farming faces the same economic and environmental challenge as the renewable energy market once faced, of cost parity. Once this is met, market forces will drive the environmental benefits as positive impact scales with growth. Technology that meets this challenge will revolutionise food production as we know it.
LettUs Grow™ have developed technology that brings the benefits of aeroponics, where plants are grown in a nutrient-dense mist, to all farmers. Yield improvements over hydroponics will drive farmers towards profit, vertical farming towards the mass market, and help all of us reduce the waste and carbon footprint of fresh produce; empowering anyone to grow delicious food near its point of consumption.
