Seedling Warmers

This thick plastic seedling heat mat has an embedded heating wire in it. Because the thermostat is outside the mat, the heat given off by the mat is related to the temperature of the surrounding air. So, when your room is cool, the mat is 5-11 degrees Celsius (10-20 degrees Fahrenheit) warmer than that. And when your room or cold frame is warm, the mat is much warmer. In late spring when the surrounding temperature (not soil temperature) is over 24 degrees Celsius (75 degrees Fahrenheit), it is best to unplug the mat so that the seedlings do not become too hot. Direct sunlight will overheat the air surrounding your flats and cause overhating as well.
