Get to know even more about the ROOT!T Heat Mat and Thermostat.
The combination of a thermostat and heat mat is a highly useful pairing that gives you full control over your seedlings' growth.
While a heat mat can be used without a thermostat, being able to set a precise temperature range is highly useful for temperature-sensitive plants, ensuring they remain within their ideal conditions and reducing the risk of exposure to unsuitable temperatures.
The ideal temperature will depend from plant to plant, so it's important to research this information for the specific plants you're growing. As a general guide, however, most seedlings will germinate best when kept between 20 and 25°C.
You should use your heat mat and thermostat during the germination and early growth stages. This helps to regulate the temperature to perfect conditions to give your plants the best start. Once your seedlings are established, you can stop using the heat mat and thermostat, especially if your plant is best suited to room temperature.
