2022 Things You Need to Know about Seedling Heat Mat




Speaking of tools for the garden or greenhouse, you may know about the pruner, the planter beds, and the water pump, do you know the seedling heat mat and what is it for? Why a heat mat is needed for the plants? The basic function of a heat mat is heating the soil. The majority of seeds germinate best in temperatures between 70-90 F. (21-32 C.), some even need a temperature that is a little bit higher. If the soil temperature is below 50 F. (10 C.), then many seeds won’t germinate at all. Of course, if the temperature is too high, the seeds won’t sprout, either. Therefore, a seedling heat mat is a great helper in the germination and growth of seeds. Let’s have a look at how to use and maintain a heat mat.

 1. Prepare the appropriate size of a heat mat and set it up.



When you plan to buy a heat mat, you need to have an idea of the size of the heat mat and how many of it you are going to need. So before buying heat mats, estimate how many plants you will cultivate and the size of the trays or other containers that you will plant them in, which will be helpful for you to get appropriate heat mats.


After you’ve planted your seeds and got your heat mats, put the heat mat under the celled trays or individual pots. Then connect the neat mat with a thermostat, if you don’t have one, you will directly plug the mat into power.




 2. Keep a close watch on the soil and your seedlings.



Have a check on the temperature of the soil with a soil thermometer. You’d better check the temperature at times to ensure accuracy even if you have equipped the mat with a thermostat. If you find the actual temperature of the soil is high, add a thin piece of wood or potholder between the trays and the mats. This can protect your seeds from being weak in too much heat.


Remember to turn the mats off or take the plants that have sprouted before others away from the mats, because the heat mats won’t benefit the sprouted seeds and excessive heat may even hurt them. Since seedlings germinate at a different pace, you need to keep an eye on them and put those germinated seedlings under bright light as soon as possible, ensuring the best effect for plants.





 3. Tips on using and maintaining heat mats.



Firstly, it is recommended to equip your heat mat with a thermostat that is worth using. Not only can it regulate the temperature of your heat mats, but also monitor the working process for you. If there is anything wrong, you can get a sign quickly from the heat mat thermostat.







Secondly, check the soil moisture daily when using heat mats. Because warm soil dries out faster than cool, damp soil, you should pay attention to how moist the soil is and water it as needed. Besides, oxygen and light are also essential for the germination process of seedlings. Do not forget these two factors!


Last but not least, do not be in contact with the plug when your hands are wet. Since water is needed for plants to generate, there will be moisture in the environment that you use the seedling heat mats. Generally, the mats are waterproof, so what you need to mind are the plug and wires. For the sake of safety, you’d better not use an extension cord. If you do need one, make sure it is heavy-duty enough or use it with other protective devices.



That’s all for our instructions and advice. Wish your seeds generate faster with the help of heat mats!
