The other type is used to speed up a plants growing process. It works by the dome trapping the heat so the plants can utilize it for their growth.

Temperature Range and Controls

Another thing you need to check is the temperature range of the warming mats. You need to make sure that they can maintain 10-20 degrees, without factoring in the ambient air temperature.

Aside from controlling the temperature, having a thermostat also keeps you updated on any changes in room temperature. This way, you can determine what other external factors may cancel out the effectiveness of your seed warming mat.
