Faced with a growing global population and an increase in extreme weather conditions, the farmers of the future may increasingly need to resort to greenhouses to produce viable crops. However, it is a fact that while greenhouses can provide a secure and stable environment to grow produce, especially in areas with extreme fluctuations of temperature, they need to be constantly artificially heated and/or cooled means they often require huge amounts of energy to function.
In recent years, glass greenhouses and cold frames are a perfect way to re-purpose solar panel glass. The rough sub-surface texture (referred to as “prismatic”) on one side of the glass is designed to trap light, repeatedly forcing the light energy into the solar cells, instead of allowing it to reflect back out. When used as greenhouse glass or as a cold frame, this glass traps more heat and light for your plants. In farming applications, this type of glass solar greenhouse can provide a large surface area for energy production. Especially in the modern farming, many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to evaluate optimality-degrees and comfort ratio of greenhouses (i.e., air temperature, relative humidity and vapor pressure deficit) in order to reduce production risk prior to cultivation of a specific crop.
Like most solar greenhouses in use, the warmer temperature in a glass solar greenhouse occurs because incident solar radiation passes through the transparent roof and walls and is absorbed by the floor, earth, and contents, which become warmer. As the structure is not open to the atmosphere, the warmed air cannot escape via convection, so the temperature inside the greenhouse rises. Meanwhile, ventilation is one of the most important components in a successful greenhouse. If there is no proper ventilation, your glass solar greenhouse and your growing plants can become prone to problems. Moreover, ventilation can also ensure a supply of fresh air for photosynthesis and plant respiration, and may enable important pollinators to access the greenhouse crop.
