Understanding temperature in growing systems

In order to improve temperature control inside of a growing system, we must understand how temperature works inside of a system with plants and the variables involved in determining temperature for our crops. There are different variables that affect the temperature in plants. Some of the most important…

Study on a ground-source heat pump system for greenhouse heating–cooling

One of the important heating criteria of a greenhouse in the northern hemisphere countries is heat availability, particularly in the winter season. Among other heat storage types, seasonal soil-based energy storage performance is auspicious. However, the performance is affected by the length and depth of…

"There is more to a retrofit than simply changing some lights"

UK: The practicalities of installing a heat-pump system

A heat pump operating at a coefficient of performance (CoP) of 2.9 or better in order to qualify for the RHI subsidy will produce water at a much lower temperature than an oil, gas, or biomass boiler. As a general rule, most heat-pump systems will produce water up to 50–55˚C. Higher temperatures are…

Passive heating and cooling of a greenhouse

Passive heating and cooling techniques have been in use for centuries. They employ inexpensive techniques that substantially reduce heating and cooling costs while reducing your carbon footprint. Ridge vents work in tandem with eave vents and/or windows to either trap the sun’s warmth during the heating…
