Naturally Ventilated Greenhouse

The naturally ventilated Poly house was designed to meet the growing needs of farmers around the world to produce higher quality crops thus enhance the return. This naturally ventilated poly house is designed to solve the problem of ventilation and humidity and is especially suited for hot and humid weather conditions. This is carried out by Fix openings located in the centre of each of the structure's arches which runs along the entire length and four sides ventilation, which runs along the entire length & breadth of the structure. These openings allow natural ventilation and release hot air.


Structure is made up of Top Quality Hot dipped galvanized round pipe and having wall thickness 2mm and covered with multilayer polyethylene.
