Seedling Heating Mat Rankings
Seed and seedling flats are often placed in windowsills, but they can get to be too hot or too cold. Both seeds and seedlings require consistently warm temperatures to thrive.
Seedling heat mats slowly increase the temperature of seed-starting mediums. This kind of gentle warmth mimics warm springtime outdoor soil temperatures. Although experts disagree about the exact sweet spot temperature, it generally ranges from 65 to 85 degrees Fahrenheit. That’s about 10 to 20 above the average temperature in most homes.
In essence, seedling mats are electric heating pads made from PVC or plastic that are placed under seedling trays. They are regulated by thermostats. These mats are made from waterproof materials and contain heating coils inside.
All you need to do is place your trays on top of the mat and plug it in. However, you should check on the temperature from time to time. Heat mats are not required for seeds and seedlings to grow, but the added heat can speed up germination!
Look for seedling heating mats that measure around 10 by 20 inches. If you have more trays, you can easily find larger mats. If you are starting from seeds, make sure to read the back of your seed packets to see what their optimum growing temperatures are.
You can remove the trays right after they sprout, keeping in mind that even if only some sprout, the others will follow suit soon after. The tray can be removed as soon as the first few seedlings start poking out, as the others have also had the benefits of the additional warmth.
- Do not use a standard heating pad for seed and seedling germination. These do not provide consistent heat.
- If you want a more inclusive germination system, look for heat mats that include grow kits with humidity domes. These keep your little green babies well hydrated!
- If you have a pet, you can put a seedling heating mat under a towel or blanket to warm up their bed. Just be sure to remove the mat once the item is heated up, as well as before they lay down.
