What are the 3 main types of greenhouse?

Generally speaking, there are three types of greenhouses: lean-to, detached, and ridge and furrow or gutter connected (Figure 1). Few lean-to greenhouses are used for commercial production because of limitations in size. This type of house is the most popular among hobbyists.

What is greenhouse how you classify it?

Based on the type of covering materials, the greenhouses are classified as glass, plastic film and rigid panel greenhouses. 2. 4.1 Glass greenhouses. Only glass greenhouses with glass as the covering material existed prior to 1950. Glass as covering material has the advantage of greater interior light intensity.

What are the characteristics of a greenhouse?

A greenhouse has a large expanse of glazing on its sides and roof so that the plants are exposed to natural light for much of the day. Glass has been the traditional glazing material, but plastic films, such as polyethylene or polyvinyl, and fibreglass are also common.

Gable-style

The traditional gable construction, with straight walls and sloping roofs that create a triangular gable on either end of the structure, works well for a greenhouse. It’s the most common design, providing plenty of sun and room to move inside.

What are the main 4 greenhouse gases?

What are the uses of greenhouse?

Greenhouses are often used for growing flowers, vegetables, fruits, and transplants. Special greenhouse varieties of certain crops, such as tomatoes, are generally used for commercial production.

What are the advantages of greenhouse?

A greenhouse is a safe haven for plants. It reduces the accessibility of insects and animals that have the potential to damage or destroy your plants. This greenhouse environment reduces exposure to extreme weather conditions such as torrential rain and droughts.

What are the 5 main greenhouse gases?

Quonset greenhouses, also known as hoop houses or polyethylene tunnels, are constructed from pipe, either PVC or metal, bent into hoops and draped with polyethylene film (See Figure 1.2). Quonset greenhouses are ventilated through roll-up sidewalls and large open doors at both ends.

What are the types of greenhouse effect?

Several major greenhouse gases that result from human activity are included in U.S. and international estimates of greenhouse gas emissions:
  • Carbon dioxide (CO2)
  • Methane (CH4)
  • Nitrous oxide (N2O)
  • Industrial gases: Hydrofluorocarbons (HFCs) Perfluorocarbons (PFCs) Sulfur hexafluoride (SF6) Nitrogen trifluoride (NF3)

What are the components of greenhouse?

The main components of greenhouse like structure, covering/glazing and temperature control systems need proper design for healthy growth of plants. Under Indian conditions, Quonset type, multispan greenhouse is most suitable, because of its low cost and ease of fabrication.

What is truss in greenhouse?

Trusses are the fundamental vertical support structure of a greenhouse (See Figure 1.14), which supports the weight of the roof. They provide strength to the basic structure and a hence placed at a distance of 2, 3, 4 feet or as required. The truss is made up of rafter, strut, and chords.

What are the advantages of greenhouse?

A greenhouse is a safe haven for plants. It reduces the accessibility of insects and animals that have the potential to damage or destroy your plants. This greenhouse environment reduces exposure to extreme weather conditions such as torrential rain and droughts.

Why do we use greenhouses?

Warmth and humidity promote plant growth. Plants need moisture, warmth and light to grow. A greenhouse stabilises the growing environment by buffering the ambient temperature and protecting the plants from extreme cold. A gardener without a greenhouse is a bit like a cook without a stove.
