What is Polyhouse?

Poly farming is essentially an outsized greenhouse that uses glass &  plastic poly film walls. In Addition, aluminium siding and sheeting, or netting instead of glass and plastic film. With more surface area for solar panels and more insulation. Between you and what nature might throw at you. It’s clear why growing in a poly house can save you money on electricity bills.

It also makes growing vegetables throughout the winter possible. Polyhouses are easy to build yourself. But many growers choose to have them professionally constructed.

This option often includes a low-cost lease option with upgrades later on. When choosing a design for your new home. Keep in mind they come in two main varieties. Those with solid walls and those with mesh coverings.

A polyhouse is an ecological house, heat-insulated against heat loss. Making it more suitable for year-round living.

The roof has skylights that allow natural light into the house. Thus avoiding reliance on electricity for lighting during the winter months.

The walls are thick enough to retain warmth at night. And minimize radiant heat loss during winter months. By means of double glazing of polycarbonate or Lexan panels. To understand polyhouse meaning read more.

In India, polyhouses are mostly made from glass reinforced plastic due to its advantages like-

  1. High tensile strength
  2. Flexibility
  3. Lightweight
  4. Easy availability at a cheaper price in the market.
  • When compared with steel, GRP is also comparatively cost-effective. Aluminium is another good option for constructing a Polyhouse. But the comparatively high cost of raw materials. Makes it costlier when compared with GRP.
  • Polyhouses are portable, high-tech greenhouses. That help farmers extend their growing season in colder climates. They offer protection from adverse weather conditions, pollution and diseases. Which allows farmers to grow more crops at once.
  • Not only does Polyhousing protect plants. From extreme temperatures. But it also provides optimal growing conditions for healthy growth. The sun shines through translucent plastic panels all day long. Without scorching plants or seeds.

Polyhouse technology– 

  • Poly agriculture, or vertical farm, is an enclosed greenhouse. That allows for year-round farming. Inside, crops are grown in vertically stacked tiers.
  • The poly house design keeps sunlight and fresh air in close proximity with plants at all times, resulting in increased yields and improved quality. There are several factors to consider when building your own polyhouse. Chief among them is determining which crops you will be growing inside it.
  • Some common examples include leafy greens (like lettuce), tomatoes, peppers and cucumbers. Get polyhouse farming information at Shriji Green.

Polyhouse VS Greenhouse

  • The main difference between a Greenhouse and Polyhouse structures. Is that poly houses are less expensive than greenhouses. But they’re not as durable.
  • However, even with fewer material costs, you can still save money by using plastic instead of glass for your structure. And it’s far easier to repair or replace if something goes wrong (such as broken plastic panels).
  • Learn more about Polyhouse and Greenhouse.

Greenhouse VS Polyhouse

Which one should you choose? One major difference between Polyhouse and greenhouse is their quality and build.

  • When it comes to durability, polyethylene plastic is more durable than glass or PVC.
  • Polyethylene plastic doesn’t crack or break as easily as glass. And it also lasts longer than traditional greenhouse frames.
  • It stands up better against strong winds and weather conditions such as hail, hurricanes, tornadoes, and tropical storms.
  • A greenhouse is traditionally made of glass panels.
  • On farms, Greenhouses are commonly used for growing flowers, vegetables and fruits.
  • Greenhouses are also called vegetable or flower houses.

By means of electric heating in cloudy periods or at night. For instance, many farmers use both kinds of heating in combination. In order to keep plants growing continuously throughout spring, summer and autumn.

Others decide not to have heating systems in their greenhouses. Since winter temperatures are not that low anyway. Which choice you make depends on your personal preferences and your location.

Due to its large surface area, a greenhouse requires more water than any other kind of house. So place close to a water source such as a river or well.

Information About Polyhouse

Polyculture, or multiple-use farming, is an age-old practice designed for self-sufficiency. The basic idea behind poly agriculture is that if you grow different types of plants in close proximity. Therefore, they will tend to protect each other. For example. Some plants provide natural insecticides. That keep pests away from neighbouring crops. While others are more vulnerable. But produce better when grown near plants that are toxic to pests.

  • A poly-tunnel or Polly house farming is an agricultural covering. Or structure that extends for at least part of its length above ground level.
  • It is traditionally constructed from galvanized sheet steel. Supported by timber, concrete, brick, stone or plastic walls. And accessed by large sliding doors at either end.
  • Poly-tunnels are particularly popular with market gardeners and allotment growers. As they provide shelter for their crops over winter. And extend growing seasons into autumn and spring.
  • When well designed, sheltered spaces. Like these can aid early-season plant growth considerably.
  • They allow earlier sowing times due to increased temperatures. Inside (particularly when light reflects off white surfaces) and help control pests that prefer cool conditions.

Advantages Of Polyhouse Farming

  • More Quality, Fewer Costs: The advantages of poly farming in India are many. In fact, if you do nothing else with your life. At least build your house from poly-glass!
  • Not only will it outlast any other type of housing by far. But it is literally impossible for insects or rodents to chew through them.
  • This saves farmers money and hassle. As pests become infrequent problems.
  • You can grow healthier polyhouse farming crops that taste better and yield more.
  • You’ll pay less in terms of both food and labour costs. Because crops stay healthier throughout their growth cycle. And harvest yields increase as well due to lack of disease outbreaks!
  • Certainly, it’s no surprise that small polyhouse plants stay cleaner and last longer before spoilage.
  • Most importantly, they simply aren’t subject to unwanted pests like those grown in open fields.

Understanding the differences and benefits of each method is crucial for farmers and stakeholders in the agricultural industry. Here is a comparative analysis of polyhouse and traditional open-field cultivation:

1. Environmental Control:

  • Polyhouse Cultivation: Polyhouses offer a controlled environment where temperature, humidity, and light can be adjusted according to crop requirements. This allows year-round cultivation, protection from adverse weather conditions, and prevention of pest and disease infestations.
  • Traditional Open-field Cultivation: Open-field cultivation relies on natural environmental conditions. Farmers have limited control over temperature, humidity, and light exposure. Crops are susceptible to weather fluctuations, seasonal variations, and pest attacks.

2. Crop Yield and Quality:

  • Polyhouse Cultivation: Polyhouses provide optimal growing conditions, leading to increased crop yields and improved quality. Controlled environments reduce crop stress and enhance plant growth, resulting in higher yields and better quality produce with consistent characteristics.
  • Traditional Open-field Cultivation: Yields in open-field cultivation can be influenced by external factors such as unpredictable weather patterns, pests, and diseases. Quality may vary due to natural variations in environmental conditions.

3. Seasonal Flexibility:

  • Polyhouse Cultivation: Polyhouses allow for year-round cultivation, irrespective of seasonal limitations. Farmers can grow crops during off-seasons, ensuring a continuous supply and potential market advantage.
  • Traditional Open-field Cultivation: Open-field cultivation is largely dependent on specific seasons and favorable climatic conditions. Growing crops outside their natural seasons may result in lower yields or crop failure.

4. Water and Resource Management:

  • Polyhouse Cultivation: Polyhouses enable efficient water and resource management. Water usage can be optimized through controlled irrigation systems, reducing wastage. Nutrient application can be precisely regulated, minimizing fertilizer runoff and environmental impact.
  • Traditional Open-field Cultivation: Water management in open fields can be challenging, as irrigation relies on natural rainfall or manual methods. Resource utilization may be less efficient, leading to higher water consumption and nutrient loss.

5. Pest and Disease Management:

  • Polyhouse Cultivation: Polyhouses provide a physical barrier against pests and diseases, reducing the need for chemical interventions. Controlled environments make it easier to monitor and manage pests, minimizing crop damage.
  • Traditional Open-field Cultivation: Open fields are more susceptible to pests and diseases. Farmers may need to rely on pesticides and fungicides to control infestations, which can impact human health and the environment.

6. Land Utilization:

  • Polyhouse Cultivation: Polyhouses optimize land utilization by allowing vertical farming, stacking multiple layers of crops. This is especially beneficial in urban or limited land areas where space is a constraint.
  • Traditional Open-field Cultivation: Open-field cultivation requires larger land areas for crop production, limiting opportunities for agriculture in densely populated region.

Polyhouse cultivation offers significant advantages over traditional open-field cultivation, providing controlled environments, improved yields, year-round production, and enhanced resource management. However, it requires higher initial investment and specialized knowledge. Traditional open-field cultivation, on the other hand, relies on natural conditions and is more accessible to small-scale farmers. Ultimately, the choice between polyhouse and traditional open-field cultivation depends on factors such as climate, crop type, available resources, and market demand.
