With the windows shut permanently, the temperature may become too high, and the windows need therefore to be opened. This will allow the temperature to drop back to the correct level. Different numbers of degrees to which the window is open have different cooling effects. For example, if the window is open by 50 degrees, then there is probably a more rapid cooling effect upon the greenhouse than if the window was 10 degrees open. Thus, it is important to know how many degrees the...
