What Does a Seedling Heat Mat Do?

A seedling heat mat is a great tool for anyone who likes to start seeds indoors. It provides warmth directly under the plants, which encourages germination by simulating what would happen in nature if they were lying on top of decaying matter or even their own parent plant.

The pad should be placed underneath your seeding pots and then plugged into an electrical socket. You can use it with any type of pot, tray, or flat that you want- planting mix isn’t required because there are holes in the bottom so excess water can drain out easily.

Some people like using compostable peat pellets instead of soil so that they don’t have to transplant later down the line when starting hundreds or thousands of plants at once!

Types of Seed Warming Mats

There are three different styles of seed warming mats that you can choose from.

The first is the heat mat with a thermostat, which has built-in temperature control so that it doesn’t overheat your seeds and fry them! Even though the mat will automatically turn itself off when it reaches its set point, I still recommend double-checking to ensure nothing went wrong once in a while since they have an automatic shut down feature.

The second style is a heat mat without a thermostat. I recommend these to people who are really good at remembering to turn things on and off because it’s easy for the temperature inside your germination chamber to get too hot when this type of heating pad doesn’t have any control over its temperature whatsoever.

The third style is called a propagation dome/tent. They hold humidity extremely well by being made out of clear plastic which makes them my favorite way to grow new plants from cuttings. They can also be used to keep your seeds warm and happy, but only if the size of the dome is big enough for your tray.


Heating mats can be used anywhere where the plants need to be provided with heat. The heat effect promotes germination, which allows plants to grow optimally. As a result, the plants grow not only quickly, but also vigorously. This has an optimal effect on the stability of the plants. Thus, the plants have even better chances to survive in the long run.

Heating mats are very suitable for root formation, seed raising, and cuttings propagation. Likewise, the heating mat is suitable for overwintering plants in the greenhouse.

A splash-proof heating mat is more suitable to facilitate handling and increase the duration of use. Thus, heating mats are a good choice for both beginners, amateurs, and experts in botany when growing plants in indoor greenhouses.
