Some plant heating mats offer an external probe or heat sensor that you can stick in the soil to gather the exact temperature of your seedlings. You likely won’t need to reach these extreme temperatures, but thermostats offer more flexibility for growing plant species that need custom settings. If you plan to grow plants with more specific needs or want more control over the germination process, you can set your thermostat to between 40 degrees and 100 degrees. That temperature range is useful for some seedlings but not for all. Heating mats without a thermostat usually heat between 70 degrees and 80 degrees.
