Growing plants from seedlings is a great way to save money on gardening. Seedlings are also a lot of fun to watch grow, and they provide you with the opportunity to try out new plants that might not be available at your local store.

The process can be daunting if you have never done it before, but all you need is the right equipment. In this blog post, we will help you find the best seedling heat mat for growing plants from seedlings in your own home.

Before buying a seedling heat mat, you must know what things to consider. These include:


There are two types to choose from:

  • Flat-Style Heat Mat
  • Growing System Heat Mat

Flat Mats:

Flat mats are usually more expensive than adhesive mats, as the latter is a lot simpler to manufacture.

However, a flat-style heat mat offers several benefits: it warms up faster; distributes heat better; provides even warmth throughout the mat; and is safer to use.

Growing System: 

Depending on the size of your trays, you can choose a heating mat that fits them all or one that covers only part of the surface area being heated.

Choose carefully depending on how many seedlings are in each tray – if there’s just one plant per container, then it won’t need much heat. However, if you’re growing four or more seedlings in a tray, then your mat should cover at least half of the surface area and be adjustable so that it could accommodate different-sized trays.

Seedling Heat Mats Buyer Guide


Another thing to consider is the material your seedling heat mat is made from. A good option should be easy to clean, safe for all plants including young seedlings, and should have a high thermal efficiency (ability to transfer heat).

A flexible heating mat that can mold itself around any shape or size container you use would also be ideal.


Another consideration is whether your seedling heat mat will be waterproof or not.

If it isn’t, you must make sure to cover the surface before watering your plants so that water doesn’t seep underneath and damage the heating elements. If the mat does get wet, turn it off immediately until all parts are completely dry again. This way, you can avoid short circuits or fires.

Power Cord length 

The last thing to consider is the cord on your heating mat. It should be long enough so that you don’t have problems with positioning, but not too long either because it will just get in the way of garden tools and soil. Look for a cord that’s about 20 inches long.


The capacity of the seedling heat mat will determine how many plants it can support. Some are more specifically designed for smaller applications, so keep this in mind when making comparisons between products.

If you plan on using multiple mats at once, make sure that they have been specifically designed for this purpose.


You need to make sure that the seedling heat mat fits in your grow room! Measure the space you have, and compare it with any product specifications before making a purchase decision.

Some are very large and heavy, so be careful not to damage anything while moving them around or setting them up where you want them.
