Summary
This controlled environment study investigates the interactive effects of hydroponic nutrient solution type (organic and inorganic formulations) and artificial light quality on lettuce productivity in a plant factory system. The work compares performance under different nutrient regimes and light conditions relevant to intensive soilless horticulture, with potential applications to vertical farming and protected cultivation.
Regional applicability
Findings are directly applicable to United Kingdom protected horticulture and emerging vertical farming sectors, where controlled environment agriculture and hydroponics are expanding. Results on nutrient solution optimisation and light spectrum effects inform UK glasshouse and plant factory operations, though local energy costs and light availability may differ from South Korean conditions.
Key measures
Lettuce growth parameters (likely biomass, leaf area, or height) under varying hydroponic nutrient formulations and artificial light spectra
Outcomes reported
The study examined how hydroponic nutrient solution composition (organic versus inorganic) and artificial light quality influence lettuce growth in a controlled plant factory system. Growth metrics and yield responses to these environmental variables were measured.
