Poly houses, also known as poly tunnels or high tunnels, are a type of greenhouse structure that is commonly used in agriculture for growing and protecting plants. These structures are made of polyethylene or polycarbonate sheets that are stretched over a frame made of metal or PVC pipes. Poly houses are used to create a controlled environment that can protect plants from harsh weather conditions such as extreme heat, cold, wind, and rain.
The construction of a poly house involves several steps that must be carefully followed to ensure the structural integrity and effectiveness of the structure. The first step in building a poly house is to select a suitable location with good drainage and access to sunlight. The site should be level and free of any obstructions that could interfere with the construction process.
After selecting the site, the next step is to prepare the ground by leveling it and removing any vegetation or debris. The frame of the poly house is then constructed using metal or PVC pipes that are bent to form the desired shape and size of the structure. The pipes are anchored into the ground using concrete footings or anchors to provide stability and support.
Once the frame is in place, the polyethylene or polycarbonate sheets are stretched over the frame and secured using clips or ties. It is important to ensure that the sheets are properly secured and do not have any gaps or tears that could compromise the structure. Ventilation windows and doors are then installed to regulate temperature and humidity levels inside the poly house.
After the construction is complete, it is important to regularly inspect and maintain the poly house to ensure that it remains in good condition. This includes checking for any damage to the sheets, frame, or ventilation systems, as well as cleaning and disinfecting the interior to prevent the spread of pests and diseases.
Overall, the construction of a poly house requires careful planning and attention to detail to ensure the success of the structure. By following the proper steps and guidelines, farmers and gardeners can create a controlled environment that is ideal for growing a wide variety of plants and crops.
