Even heat output: the heating mat plants uses graphene heating technology, whether fast seed tray or heated plate terrarium, to ensure even heat distribution and high heat energy efficiency.IMPROVED LOW TEMPERATURE GERMINATION The germination heat blanket provides the ability to germinate seeds faster in a cool environment. After the plant heating pad is connected for 20 to 30 minutes, it increases the root temperature of the plant by 10 to 20 degrees Celsius compared to the ambient temperature.Easy to use: Power: 20 watts, low energy consumption. Voltage: 220V~230V Simply place it under the flower pot and connect it.Intended use: ideal plant heat mat, very suitable for growing greenhouse in indoor greenhouse, the growth of vegetables, flower growbox and other aquatic plants as well as the aquaculture of ornamental fish in glass containers, beer brewing etc.Notes: 1. Do not immerse the heating pad in water. 2. Do not fold the heating pad.
