Poly Tunnels

Poly Tunnels are basically naturally ventilated climate controlled. Metal TechPoly Tunnels have a variety of applications, the majority being, growing of vegetables, floriculture, planting material acclimatization, fruit crop growing for export market.

Metal TechPoly Tunnels are built of a Pre-galvanized Tubular Structure wherein crops are grown under a favorable controlled environment and other conditions viz. temperature, humidity, light intensity, ventilation, soil media, disease control, irrigation, Fertigation and other agronomical practices throughout the season irrespective of the natural conditions outside.

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.

ain Poly Tunnels are available in different sizes and constructed as per customer requirement. The sizes vary from as small as 96 Sq. M to 500 Sq M and more.

The degree of sophistication also varies from a simple Poly Tunnel with polyethylene film covering to highly sophisticated, fully automated drip and foggers systems, full scale computerized (fully automated) systems.

  • Yield increases by 5 - 10 times or even more.
  • Uniform and better quality
  • Reduction in labour cost
  • Less fertilizer requirement, thus reduction in fertilizer cost.
  • Low water requirement thus saving in water.
  • Less chances of disease attack, thus reduction in disease control cost.
  • Higher Efficiency of Water & Fertilizer Use.
  • Cultivation in problematic topography.
  • Cultivation in problematic soil conditions.
  • Cultivation in problematic climate conditions.
  • Requires less area to get maximum yield and benefits.
