Nitrate• Leafy vegetables such as lettuces and spinach
are high in Nitrate.• Health concern. • EU regulation + Retail requirements
Research hypothesis:
– Nitrate accumulation = low light level
– Optimized photosynthesis light spectrum
– Minimize nitrate in irrigation
– Pre-harvest light recipe to accelerate nitrate
reductase

Vitamin C (mg/kg)
Vitamin C tomatoesWhen grown in the greenhouse, tomato fruit typically have low levels of vitamin C. Light is the major regulatory of plants vitamin C content. Increases of more than 30 % is observed after illuminating the detached fruits with LED lighting.

TasteBasic sugars, acids and volatiles
Research hypothesis:
Light influences the production of secondary
metabolites/volatiles
UVB accelerate volatiles biosynthesis
18 Philips Lighting Research
Volatiles• Taste is a matter of cultivar but also light

Shelf life test are being done at the moment and are showing some differences depending on climate, pre-harvest conditions, climate and light condition at harvest and post-harvest handling.Light level before harvest is very important for shelf life and overall visual quality.

Conclusions
Vertical farming enables control of all the
growth parameters
Yield, Quality and Nutrient are controlled
this is a revolution in food production
Eating fresh, locally grown, healthy
vegetables, pesticides free, all year long
will transform the food chain and impact
human health
