Heat mats will usually come in a variety of sizes. The basic size and any rug that seems to be available are 10 x 20 inches. These mats will be suitable for standard seed pots.
You choose to buy this type if you intend to sow seeds in a standard pot. When you sow in larger places, you have to select a different size. Small mats will not be hot enough for large pots.
20 x 48-inch mats can be used for 4 standard pots at the same time. When you need a large number of seeds, you use more than 4 then roll mats will be suitable for you.
The choice of size will be determined by the number of varieties that you intend to sow. Ideally, the meat should be medium or larger than the pot to increase the temperature of the seeds.
2. The Style of the heat mat
Currently, there are two main types of carpets:
- Flat carpet: This type of carpet has a small size suitable for those who grow plants in indoor pots. These low-cost mats typically provide an extra 10-20ºF for plants.

4. Temperature range and temperature controller
The temperature you provide for seeds and seedlings, in the beginning, needs room temperature for 10-20 minutes. Today, all heat mats provide such a stable temperature range. Others will have a wider temperature range, like 40 – 108ºC.
