In collaboration with Schoneveld Breeding, Patron realized a highly advanced production greenhouse for the new construction site in Wilp. Schoneveld Breeding is innovative in breeding flowering potted plants and has made significant sustainability efforts in this new construction. Patron designed a closed water system with 100% reuse of available resources.

An advanced micro-dosing unit prepares no fewer than 13 recipes, which fill the daily supply tanks. In the corridor surrounding the production greenhouse, a crane set with a crane matrix allows for manual selection of the correct recipe for each section before the irrigation water is transported to the plants. The plants are placed on both fixed and movable tables, with an electric valve controlling the setup and drainage of the table. A float system ensures that watering stops at a minimum water level of 8mm. Each table has 5 different setup pipes and 9 drainage pipes with return pits. After passing through the sieve bend, the drain water is disinfected and collected in separate silos.

From here, the cycle starts again. The piping system is installed in a ring configuration, allowing the water to be flushed for refreshment. Notably, the project uses Philips LED lighting, Agrolux growth light fixtures, and PAR and IR cameras in each section. Fresh outside air is brought into the cultivation area from the greenhouse ridge through the Hinova VentilationJet system with an inflow unit mounted on the trellis between the 4 screen cloths. The desired inflow capacity for drying or cooling is determined by the Hoogendoorn ISII. Vertical fans (Hinovator) distribute the air vertically within the space.

The complex infrastructure of multiple irrigation pipes was a challenge for the designers, groundworkers, and installers, but it has resulted in a unique project that meets the high demands for dosing and uniformity.
