Polyhouse farming is a type of greenhouse farming perfect for small hold or commercial ventures.
The material used in the construct is easily accessible, cheap yet durable material. Materials used in playhouse construction are glass, polyethylene. However polyethylene is most widely used because of the popularity and cheaper cost.
Polyhouse farming involves building a polyethylene green house, climate control and managed resources. The major advantage to this type of farming is high yield, managed resources, huge profit.
Benefits of polyhouse farming
Benefits of polyhouse farming is the highly organic nature of the system. Regardless of weather conditions, climatic and temperature control system provides better yield. The Farming is perfect for off season farming, growth of health crops and faster growth. There are fewer pests, increased yield, good management of fertilizer.
- Highly organic nature
- Temperature control
- Grow in off season
- Healthier crops
- Fewer pests
- Increased yield
- Easier management
- Good fertilizer management
Disadvantages of polyhouse farming
Disadvantages of polyhouse farming are poor airflow, however naturally ventilated polyhouse have better advantage than artificial polyhouse. Another challenge is the high structure, utility bill, rapid depreciation of construction materials.
- Poor air flow
- High structure
- Utility bills (artificial polyhouse)
- Rapid depreciation
Advantages of polyhouse farming
Advantages of polyhouse farming are use of cheap translucent polyethylene material, controlled environment. Others are higher yield, high crop value, organic and managed resources. Perfect temperature control involves lights, temperature, humidity, pest control, organic soil.
- Cheap translucent polyethylene material
- Controlled environment
- Higher yield
- High crop value
- Pest control
Types of polyhouse
Types of polyhouse are either naturally ventilated or environment controlled polyhouse. Environment controlled polyhouse are perfect for off season farming. It involves temperature control, humidity control, pest control and light management. Natural ventilated polyhouse use vents located at sides or top of the greenhouse.
Further division of polyhouse
Polyhouse are further divided based on span. The span is either single, ridge and furrow. The span is either low technology, medium or high tech.
Low grade polyhouse
Low span technology use easily accessible cheap material like bamboo. The bamboo is used as support for the structure. Others are use of UV film, shades for light control, humidity and temperature control.
Middle grade polyhouse
Mid technology span are more sturdier than bamboo span. Mid technology use galvanized iron rods and thermostat temperature control.
High grade polyhouse
High grade polyhouse use automated system and high technology. Constructed with more durable material it is perfect for commercial production.
Types of crops in a poly house
Polyhouse farming easily accommodate different types of crops. Any crop that can grow in a greenhouse system is perfect for polyhouse. Grow vegetables, fruits, crop plants based on interest and market. A good crop to consider is tomatoes, peppers, dwarf trees, grapes, lettuce.
How to construct polyhouse
To construct a polyhouse it’s important to understand how they are put together. A polyhouse is similar to greenhouse, however the materials used in the construct are less durable. A polyhouse is built with basic, locally available material. They are either low, mid or high technology depending on the architects design.
They come in different Sizes
They generally differ in sizes based on land size or farmers requirements. You have the small to medium or large structure’s. The smaller to midrange structures are perfect for small farmers, while the bigger structure are more suited for commercial farmers.
Different types of polyhouse
The different types include those with environment controlled, some with natural ventilation. You can They are further devide them based on material used in building the farmhouse and technology.
Types of technology in polyhouse
Common technology in polyhouse system are temperature control, humidity, and type of ventilation. Others are type of fertilizer, flower beds, pest control mechanism.
Advantages of poly house system
The main advantages to poly house system is good temperature control, adequate pest control. More include low cost material, cheap maintenance, low cost materials. More advantages are a pest free environment, use of organic compounds and higher crop yield. The few disadvantages are wear and tear from weather conditions, minimum airflow and utility bills.
Polyhouse farming advantages
- Greenhouse technology
- Decent temperature control
- Easy to maintain
- A pest free environment
- Higher crop yield
- Organic compounds
- Low cost investment
- Cheaper materials
How to construct poly house
Reasons to construct poly house are better yield, modified climatic conditions. The type of poly house will determine materials used in the construct. Common materials are UV stabilizer film, bamboo, galvanized steel, support sheath. More are transparent polyethylene, iron rods roof support, garden beds.
How to construct poly house
To construct polyhouse use local fabricators in your area or DIY. The materials are easily sourced and readily available. polyhouse structure resembles a small warehouse. Because the high roofs are arched for good ventilation. Builder’s deploy support beams made from bamboo or galvanized steel. Make sure it has a door and span on the roof and sides. Then cover with transparent polyethylene material, add flower beds in rows. Higher technology polyhouse have temperature control, humidity control system, sprinkler system, and irrigation system.
