What To Look For In A Good Seedling Heat Mat

With the variety of choices on the market, choosing a good seedling heat mat can seem confusing. A wrong choice could be deadly for your plants since the temperature can be too cold or too warm for them to germinate, leaving you with “cooked” and dead roots. And while you should be careful when you water your plants and give them enough exposure to light, the heating shouldn’t be taken for granted either. There are many different features you should consider when choosing the right seedling heat mats.

Other than the price, you should consider the following characteristics:

1. Temperature

The majority of plants require similar conditions to grow, including temperature. Before purchasing seedling heat mats, you should do research and find out about the requirements of the plants you want to buy. Then search for the mats that offer those features.

2. Temperature controller

When thinking about the right temperature, you may get confused if you want to grow a lot of different kinds of plants that require different treatment. You can fix that problem if you purchase a seedling heat mat that has a temperature controller, or if you already own heat mats, buy only the controller, and be sure that the amount of warmth your seeds get is precise and accurate.

3. Material

As mentioned before, the material of the seedling heat mat is extremely important. You want to buy a mat that will last you in years to come since a lot of them aren’t very cheap. The fabric should be high-quality and durable, as well as waterproof. Since you’re going to water your plants, there’s a big possibility of spillage that can be risky if your seedling heat mats aren’t waterproof. It’s also much easier to clean.

4. Flexibility

We’ve already mentioned that a seedling heat mat can be used for other things as well like for example brewing beer or keeping your pet’s bed warm. When it comes to bottles and beverages, it’s nice to have heat mats that you can wrap around the bottle without worrying about it being damaged. It’s also easier to store away a mat that can be folded.

5. Dimensions

According to the dimensions of the tray, pot, or planter you have or want to purchase, you should choose the right dimensions of the seedling heat mat as well. There are plenty of different sizes and models on the market, and if you already have a favorite brand or mat model, there’s a big possibility that they offer more than one size of the chosen mat.

6. Do you need the whole kit? ­

Like you saw, a lot of brands offer a hole germination system that includes a heat mat, a tray, a planter, and a dome. They usually cost more, but they can be really convenient if you really need all of those things. If, however, you already own everything other than the mat, is better to invest that money into a good-quality heat mat.
