Abstract

Indoor plant production in greenhouses and vertical farms is essential in Nordic countries because the climate does not permit field cultivation of several important species. This project aims to improve illumination methods and nutrient recirculation to better support local cultivation near consumers, with lettuce, baby spinach, and woodland strawberry as target crops. Pulsed LED illumination and spectral optimization of background light, accounting for the photosystem properties of the tested species to maximize photosynthetic activity, are being investigated under controlled conditions. Extensive phenotyping of plants is being carried out using multispectral (PlantEye F600, Phenospex) and hyperspectral (Specim FX series, 400-1700 nm) imaging technologies to monitor their growth, health status, and molecular properties such as chlorophyll a and b levels. Combined illumination and fertilization tests using cyanobacteria to recirculate nutrients from greenhouse wastewater will be conducted later in the project. These advancements will enable plant growth in urban areas near consumers, reducing transportation costs and the environmental footprint of agriculture.
