Definition of a greenhouse
What is greenhouse in simple words?
A greenhouse is a building with glass walls and a glass roof. Greenhouses are used to grow plants, such as tomatoes and tropical flowers. A greenhouse stays warm inside, even during the winter. In the daytime, sunlight shines into the greenhouse and warms the plants and air inside.
What are the 4 types of greenhouse?
Shape. Classification of a greenhouse is according to its basic shape. Types include Gable, Flat arch, Raised dome, Sawtooth, Skillion, Tunnel.
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 a greenhouse and why is it important?
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.
What is the most common type of greenhouse?
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.
Is there a difference between greenhouse and hothouse?
Greenhouses can also protect plants from wind, rain and animals. Glasshouse is a form of greenhouse. Glass was once the only material suitable for this purpose, so glasshouse and greenhouse were pretty much synonymous. Hothouse is a heated greenhouse for plants that require an even, relatively warm temperature.
What makes a good greenhouse?
Stability: a greenhouse offers a predictable environment which shelters tender plants from damaging weather extremes. Self-sufficiency: a greenhouse empowers us to easily save and germinate our own seeds, making it possible to avoid paying for commercial starters.
What are the pros and cons of a greenhouse?
Top 10 Greenhouse Pros & Cons – Summary List
| Greenhouse Farming Pros | Greenhouse Farming Cons |
|---|---|
| Increase in yields | Expert needed in the setup process |
| Optimal conditions for plants | Growing plants is not easy |
| Protection against wind | Significant maintenance costs |
| Protection against droughts | Pollination problems |
Are greenhouses good for the environment?
Environmental Impact
In a greenhouse, growers can supplement sunlight with LEDs, allowing plants to grow faster and stronger. Greenhouse growers also use significantly less water as system water can be filtered and reused within the operation rather than simply being discharged into the ground.
What are common types of greenhouse coverings?
The most common options available are Solexx twin-wall covering, twin-walled polycarbonate, single-walled polycarbonate and polyfilm plastic greenhouse covering. Each greenhouse covering material has its own advantages, so it is important to consider your particular situation before making a decision.
What is Quonset type greenhouse?
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.
Can a greenhouse have a flat roof?
A greenhouse can have a flat roof, but curved or arched designs are typically more common. These structural differences help the building stand up to the elements, such as rain, which may pool water on top of the structure and damage the roof.
What is a gable roof greenhouse?
Gable-roof greenhouses are also known as post-and-rafter models. Like A-frames, they’re one of the most common backyard greenhouse options on the market. Gable-roof greenhouses look like mini houses or cabins. The roof of these structures has a main center rafter held up by supporting walls.
Which is also called as Mini greenhouse?
A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather.
Does a greenhouse need to be sealed?
Sealing the bottom of your greenhouse is very important because it keeps cold air from leaking in and destroying your plants. The trick is to seal the gaps where the foundation meets the frame, using a high-quality caulk or silicone.
Do greenhouses have to be clear?
A greenhouse roof does not need to be clear. A clear roof has its benefits, such as direct sunlight for seedlings, but opaque roofs are an option as well. Opaque roofs provide diffused sunlight which is better for environmental control within the greenhouse.
