Square Roots is pioneering a program that aims to transform indoor vertical farming by eliminating the need for artificial lighting, a move that promises to significantly reduce energy consumption and carbon emissions associated with traditional indoor farming practices. Funded by the Bill & Melinda Gates Foundation, the initiative utilizes CRISPR gene-editing technology to enable plants to grow heterotrophically by absorbing carbon from acetate, rather than relying on photosynthesis. This innovative approach has the potential to revolutionize the economics of indoor farming, making it a more viable solution for producing food in low and middle-income countries that are particularly vulnerable to climate change. The program's focus on sustainable acetate production and heterotrophic plant growth, based on research by Dr. Robert Jinkerson and Dr. Feng Jiao, sets the stage for scaling up these technologies for commercial use. Looking ahead, Square Roots plans to extend its "dark growth" method beyond leafy greens to include more nutrient-rich crops like sweet potatoes and cassava, which are essential for food security in many parts of the world. This expansion aims to leverage indoor farming's benefits—such as year-round production and reduced need for pesticides—while overcoming one of its biggest challenges: high energy costs associated with lighting. With the support of groundbreaking scientific research and a strong collaboration with experts, Square Roots is positioned to lead a significant shift towards more sustainable agriculture practices. This effort not only showcases the potential of cutting-edge technology to address global food supply challenges but also reflects a broader commitment to ensuring a sustainable and secure food future in the face of climate change.
