A Professional Buying Guide on Heating Mats:


One of the most challenging parts of growing a garden is starting transplants from the seed stage. This becomes even trickier when the days turn cold. Expert gardeners and hobbyists consult the best heating mat reviews to find viable solutions to this concern. Most plants will take root at room temperature. However, a little warmth can go a long way. For instance, tomatoes, eggplant and pepper sprout better in warmer soil. The most reliable products help grow seedlings faster for convenient transplanting. There are some things you’ll need to take note of before buying a unit. After all, you’ll be depending on such a device to grow robust plants so there’s a lot riding on the choice you make.



There are plenty of affordable products out there to help your plants germinate easily. These products can help you have a cheap alternative to heating the entire room, such as your garage or basement, where you place your seedlings to coax them into taking root before transferring them to your garden plot. It is important that whichever one you purchase, it has to be a highest rated product built with strong heating wire and thick construction. This will ensure consistent heating and durability to survive harsh greenhouse environments. Preferably, the heating mat should be heat bonded and not merely glued, and should stay sealed. Aside from being strong in construction, the device should also be waterproof or water resistant, ensuring safe use.



The best heating mat for the money offers uniform heating whether you use it indoors or outdoors. It should decrease the damage in plants by offering consistent air circulation. The device should be versatile enough to use both for root cuttings and seed sprouting. It should also be energy efficient. Instead of having to purchase seedlings, you can simply plug the unit in and wait to grow your own seedlings in propagation trays for transplanting to your garden. This can save you money in the long run. The best rated heating mat warms root areas to 10 to 20 degrees Fahrenheit more than ambient temperature. High-end brands can even be thermostatically controlled to ensure even heating and keep temperature variability from slowing down germination


Integration and Flexibility

Most top ten heating mats have sizes that match the characteristic foot print of seed flats. 9” by 19.5” units hold one standard seed flat, a 20” by 20” unit holds two flats and a 48” by 20” product holds four flats. The most popular heating mats typically do not have thermostat controls but they do work well with a thermometer or a separately bought heat mat thermostat. They should integrate well with storage containers or trays and propagation domes that gardeners use to germinate seedlings. Gardeners can use the unit with grow lights. Normally, heating mats have the watering, light and planting information and germination times for annual flowers and popular vegetables printed on the heating mat for easy reference. The device can even be placed underneath a reptile cage to give pets some warmth.


Things to consider:

  • Durable and quality construction to ensure long-term use
  • Uniform heating and air circulation
  • Flexibility and ease of use
