Innovations active air and ventilation jet in practice

Dehumidification is made possible by introducing dry air from above closed screens into greenhouses. This new method has been used with success in the Fresh Valley tomato farm in Maasbree, the Netherlands. Within the context of the High Tech Greenhouse 2020 project (HTG 2020) a variety of innovations are being demonstrated in practice including to do with climate, energy, substrate and water.

Hoogendoorn has been successfully using the new Active Air programme with this new method for dehumidification in vegetable cultivation. Another new development is also the Ventilation Jet, in which cold and dry air is blown into the cultivation area through a ventilator and via a casing in the protective screens. A distributor ventilator (under the screens) then distributes the air horizontally and vertically throughout the greenhouse. Tests have shown that low investment and limited operational costs are an option for such effective dehumidification.

This innovation was developed by agencies including Vostermans, Hint, Svensson, Fresh Valley and Hoogendoorn.

Hoogendoorn iSii is responsible for Fresh Valley's climate, energy and irritation management via Letssgrow.com, where on-line monitoring takes place so that researchers can follow results.
