Questions tagged [temperature]

For questions about thermal environment. Use this tag with questions about the effect of different temperature levels on plants, landscape elements, insects and pests or how to create an environment with certain temperature levels. If possible indicate temperatures in questions in both Celsius and Fahrenheit degrees.

Use this tag for questions about the temperatures required or tolerated by specific plants. Note that some other tags (eg. , ) may be more appropriate to the specifics of your question.
