Intelligent greenhouse with climate control system
Description
IMDEA Water’s top-of-the-range smart greenhouse is specially designed to withstand the demanding conditions of the research environment. It is a Reylux R9 model with a wide wing and gable roof, with a surface area of 100 m², a total height to the zenith of 5 m, and a roof and walls made of colourless cellular polycarbonate with protection against UV radiation. It is characterised by its airtightness, insulation and resistance to humidity, which translates into high energy savings.

Applications
The greenhouse equipment allows various types of tests to be carried out, both in hydroponics and in soil and/or amendment:
- Crop productivity: assessment of the impact of irrigation with water of different qualities, which has been subjected to different treatments, on crop yields in terms of quantity of crop per area of soil.
- Plant selection: evaluation of ecophysiological parameters for the selection of plant species, including large plant species (e.g. Populus spp., Salix spp., Typha spp., etc.), for use in Nature-Based Solutions, such as vegetation filters or wetlands.
- Nature-based solutions: small-scale trials of attenuation of chemical (e.g. nutrients, pharmaceuticals, metals, etc.) and biological (e.g. viruses, parasites, antibiotic-resistant bacteria) contaminants, using selected plant species, for water purification and soil phytoremediation.
- Public health risk: tests to assess the risk to food safety arising from the transfer of contaminants into the food chain via edible tissues of horticultural plants (e.g. Lactuca sativa L., etc.).
- Environmental impact: tests to assess the ecotoxicological impact of pollutants on the soil-plant system, such as soil microbiological activity (e.g. enzymatic activity, microbial biomass, etc.) and different morphological and physiological parameters of plants (e.g. leaf area, etc.).
- Runoff and infiltration: tests using devices that simulate water movement by runoff and/or infiltration processes, with or without vegetation, to assess the mobility of pollutants present in soil or water, such as micronanoplastics.
- Growth trials under different nutrient concentrations in hydroponic systems.
- Validation of the reuse of metland® output water in horizontal hydroponic and vertical aeroponic systems.
