Optimization of Phytonutrient and Vitamin Content of Salad Leaves Grown in an Intensive, Multi-Level Hydroponics System Using LED Lighting

he production of salad leaf products using LED lighting in intensive hydroponic systems is on the rise. Multi-level, hydroponic plant production units are potentially more water, nutrient and energy use efficient, compared with outdoor or glasshouse production systems.

Optimization of this technology is required for the technique to reach its full potential. In particular, it is highly important to ensure that the vitamin and phytonutrient content of the hydroponic products match those grown in natural light conditions under polythene tunnels or in glasshouses.

Manipulation of the light environment, to produce high levels of phytonutrients in hydroponics would permit food production in unusual spaces (i.e redundant buildings, shipping containers) reducing pressure on limited agricultural land. At the same time, hydroponics can optimize energy inputs and, potentially, reduce losses from disease.

Thus, this project aims to use photobiology to establish a large scale, hydroponic system to produce high quality and nutritious salad herbs in a sustainable manner.

This important project will help to improve consumer acceptance of such products grown inside sealed production buildings or in unusual spaces, such as redundant buildings or converted shipping containers.

Applicants should have a first or upper second degree in biology, biochemistry or related subjects.
