WebYour greenhouse can use the sun’s energy alone to warm the greenhouse by 20 to 30ºF. At night, there is no sun to heat, so the greenhouse temperature will match the outside. However, winter vegetation germinates best between 55 and 70ºF, and warm-season plants will germinate best between 70 and 85ºF. WebFeb 17, 2024 · Calculate your greenhouse heating and cooling requirements. The purpose of a greenhouse is to maintain a stable climate for the plants growing within, and that typically requires the use of some additional heating in the winter and ventilation during the summer.
Web4.1 Most undesirable heat loss from a greenhouse occurs by long-wave radiation, conduction and convection (qrc) and by infiltration (qi). Heating requirements are determined by calculating the sum of qrc and qi based upon the guidelines in 4.6 and 4.7. 4.2 The heat loss by radiation, conduction and convection, qrc,(Wor Btu/h) can be …
