DIF is a greenhouse technique involving temperature control for the purpose of controlling plant internode length and thus elongation rates. DIF's effectiveness has led to a reduction in the need and use of chemical plant growth regulators. Although many common greenhouse plants do react strongly to -DIF, there are some plants which show little ...
Sheep under solar panels in Lanai, Hawaii. Agrivoltaic practices vary from one country to another. In Europe and Asia, where the concept was first pioneered, the term agrivoltaics is applied to dedicated dual-use technology, generally a system of mounts or cables to raise the solar array some five metres above the ground in order to allow the land to be accessed by farm machinery, or a system ...
Currently, the greenhouse industry is the largest component of the CEA industry but another quickly growing segment is the vertical farming industry. Controlled Environment Agriculture has the ability to produce crops all year round, with the possibility of increased yield by adjusting the amount of carbon and nutrients the plants receive.
By reducing heat inside greenhouses, the company claims crops can be grown with as much as 30% less water, and less energy required in a greenhouse with mechanical cooling.
A time switch (also called a timer switch, or simply timer) is a device that operates an electric switch controlled by a timer. Intermatic introduced its first time switch in 1945, which was used for "electric signs, store window lighting, apartment hall lights, stokers, and oil and gas burners." A consumer version was added in 1952. [1]
The specific term used depends on the material and heating system used in the building. Nowadays, greenhouses are more commonly constructed with a variety of materials, such as wood and polyethylene plastic. [2] A glasshouse, on the other hand, is a traditional type of greenhouse made only of glass panes that allow light to enter.
