Better like using vertical farm key tool higher lettuce crop yields : 700 kg per square metre possible in theory

Vertical farms are extremely energy-intensive. This is primarily due to the lighting. It is therefore important to produce as many kilograms as possible per mole of light provided. This is expressed in light utilisation efficiency (LUE). You can prove improve LUE in four ways, both in vertical farms and in the greenhouse. Research shows that positive effects of adding far-red LED light. Lighting dynamically can also be beneficial.
