Study Notes
Types of Greenhouses based on Shape
- Even-span greenhouses: two roof slopes of equal pitch and width, constructed on level ground, attached to a house at one gable end, with a span of 5-9m, length of 20-25m, and height of 2.5-4.3m.
- Uneven-span greenhouses: constructed on hilly terrain, with roofs of unequal width, wider roof faces south for maximum solar gain.
- Lean-to greenhouses: attached to the side of an existing building, with a total width of 7-12 feet, and length as the building it is attached to.
- Ridge and Furrow greenhouses: consist of many even-span structures placed one after another, with a gutter connection.
- Saw tooth type greenhouses: designed for areas with high temperature, with provision for natural ventilation, and a specific natural ventilation flow path.
- Quonset greenhouses: framework consists of curved bars or tubes, covered with white polyethylene film, used for winter nursery stock.
Types of Greenhouses based on Utility
- Active heating system of greenhouses
- Active cooling system of greenhouses
Types of Greenhouses based on Construction
- Wooden framed structure
- Pipe framed structure
- Truss framed structure
Types of Greenhouses based on Covering Material
- Glass greenhouses: provides good transmission of light, transmits 84-87% of available visible light
- Plastic film greenhouses
- Rigid panel greenhouses
Types of Greenhouses based on Cost Investment
- Low Technology Greenhouses: less than 3m in total height, with poor ventilation, relatively inexpensive and easy to erect, with little or no automation
- Medium Technology Greenhouses: vertical walls more than 2m but less than 4m tall, with total height usually less than 5.5m, with roof or side wall ventilation, and varying degrees of automation
- High Level Greenhouses: wall height of at least 4m, with roof peak up to 8m above ground level, with roof ventilation and side wall vents, and cladding with plastic film, polycarbonate sheeting, or glass.
