In Gloucestershire, one of the UK’s most technologically sophisticated indoor farms has commenced operations, revolutionising the way salad crops are cultivated. Utilising a controlled environment, this vertical farm enables the growth of lettuce, basil, and other herbs three times quicker than traditional outdoor farming methods. Glyn Stephens, the head grower, describes the transition to this high-tech method as a significant shift from conventional farming, highlighting the extensive use of technology and engineering within an indoor setting.
The farm, resembling more of a warehouse than a traditional farm, utilises rows of trays under vibrant, multi-coloured lights to cultivate various salad crops across fifteen levels, maximising the use of space vertically. With a total growing area of 14,500 square metres, the environment is meticulously controlled to maintain a temperature of 27 degrees and about 75% humidity, creating ideal conditions for rapid plant growth. For instance, basil can progress from seed to harvest in just 18 days, a stark contrast to the slower growth rates experienced outdoors, particularly in regions like Spain or Morocco during the winter months.
This method of farming not only accelerates growth but also significantly reduces carbon emissions compared to importing crops from abroad. Despite the high energy demands, particularly for LED lighting and climate control systems, the farm exclusively utilises renewable electricity sources to minimise its carbon footprint. This approach to farming offers resilience against weather-related challenges and pests, thanks to its tightly controlled bio-security measures.
However, the vertical farming industry has faced financial challenges, with several firms across the globe struggling with high operational costs. Yet, the Jones Food Company, behind this Gloucestershire farm, remains optimistic. By selling their salad bags at competitive prices and focusing on energy efficiency, they believe they have found a sustainable model for year-round food production. James Lloyd-Jones, the company’s founder and CEO, asserts that they have successfully navigated the commercial challenges of the industry, positioning themselves as a viable solution for sustainable agriculture.
