What To Look For In A Good Seedling Heat Mat


With the variety of choice on the market, choosing a good 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 heat mat.

Pot Holder

Container Holders

Intelligent Garden Kit

Self-Watering Systems

Terrarium

Hanging Planters

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

1. Temperature 

Majority of plants require similar conditions to grow, including temperature. Before purchasing a heat mat, you should do research and find out about the requirements of the plants you want to buy. Then search for the mat that offers 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 heat mat that has a temperature controller, or if you already own a mat, 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 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 mat isn’t waterproof. It’s also much easier to clean.

4. Flexibility 

We’ve already mentioned that a 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 a mat 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 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 the 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 investing that money into a good-quality heat mat.
