• • • • • • • Baby leaf lettuce grown under Valoya AP673L has 58% higher biomass in average compared to baby leaf lettuce grown under a RB LED source.

• • • Plants grown under Valoya AP673L were significantly larger in size compared to a RB light source. Picture was taken 18 days after sowing.

• • • • • • Not only the spectrum, but also the light intensity shapes the plant and affects the morphology. The ‘ Multiblond ’ lettuces were grown under Valoya AP67 spectrum with 50, 75, 100 and 125 umol light intensity, respectively. 10

• • • B A A= Red oak leaf lettuce was grown first week under 50 umol, after which it was grown under 50, 75, 100 or 125 umol for 21 days. B= first week under 50, 75, 100, or 125 umol and then 21 days under 50 umol. Light intensity affects plant morphology and secondary metabolite activity, such as anthocyanin production. 11

• Plants are sensitive to photoperiod. • Some plants flower in short day, some in long day. Most leafy vegetables are day neutral and can be cultivated in long day conditions. • One should consider both the photoperiod and DLI when thinking about the lighting hours • DLI = µmol/m/s x (3600 x photoperiod)/ 1000 000 • Treatments: • PAR 125, photoperiod 18, DLI 8.1 • PAR 185, photoperiod 12, DLI 8.1

Tree seedling propagation in Sweden • Nordic trees at Holmen Skog Nursery in Sweden • Multi-tier environment will increase number of crops per year from 4 to 7. • Valoya developed a tailor-made spectrum for spruce seedlings. The new spectrum provides fast growth and rooting. | Multilayer Growing 14 14 Confidential

Strawberries in Urban Environment Agricool (FR) uses Valoya AP67 spectrum in their cooltainers for strawberry cultivation. Cooltainers are used in cities, such as Paris, to produce local food for its citizens. Valoya AP67 spectrum promotes vegetative and generative growth and enhances truss elongation of strawberry. Due to the quality of the spectrum, bumble bees can navigate in this no-natural light environment enabling efficient pollination of the flowers.
