Engineered to enhance photosynthesis without external energy, this film converts green light into more effective wavelengths while also passively cooling the soil. Customisable for different crops, it boosts yields by up to 30%, lowers water and pesticide use, and removes the need for artificial lighting. Suitable for greenhouses, vertical farms, and open fields, it offers a low-cost, scalable solution for sustainable agriculture, particularly in regions where energy access is limited and climate resilience is critical
