Pollen-sealed vegetable breeding cabinet, has air guiding and filter systems, and exhaust system ensuring constant low-pressure in cabinet during operation and air extraction when opened by ventilators

摘要

The cabinet has an air guiding system (8), a filter system (9) and an exhaust system, which ensures constant low-pressure in the cabinet during operation and ensure air extraction when opened by ventilators. An air conducting grid is formed from unfolded and folded paper or cardboard web, where exhaust air is guided through the grid and causes swirling-free airflow from an access door. A substrate or a vegetable base is placed in a sealed PVC-hose whose dimension is matched to an inner volume of the cabinet.
