Walk in Tunnels are basically the protected structure made from galvanized pipe and covered with UV Stabilized Plastic Sheet. Generally Walk in Tunnels are used to give favorable controlled environment like temperature, humidity, light intensity, ventilation, soil media, disease control, irrigation, Fertigation and other agronomical practices throughout the season irrespective of the natural conditions outside. Walk In Tunnel have variety of applications, the majority being, growing of vegetables, floriculture, planting material acclimatization, fruit crop growing for export market.
In conventional Agronomical practices, the crops are being grown / cultivated in the open field under natural conditions where the crops are more susceptible to sudden changes in climate i.e. temperature, humidity, light intensity, photo period and other conditions due to which the quality, yield of a particular crop can get affected and may be decreased.
Walk in Tunnels are available in different sizes and constructed as per customer requirement.
