OK. Today we will cover indoor temperatures, air circulation and humidity. It is important to keep in mind that indoor temperatures vary from season to season and that the temperature just inside a window may be quite different from that of the rest of the room.

Therefore, leave only hardy plants near the windows and move the others. Conversely, high window temperatures may also be a problem. South facing windows in summer and late afternoon sun in a westerly facing window, even in the winter, may cause excessively high temperatures. As for air circulation, drafts that occur due to the mixing of cold and warm air temperatures increase what is called transpiration , or the evaporation of water from the surface of the plant. Combined with chilling, this can be very detrimenta...
