An Aluminum Foil Heating Mat is a flexible heating device designed to provide consistent bottom heat for seed trays and young plants. It typically consists of:

Electric current flows through the embedded heating element.
The element generates heat, which is spread evenly by the aluminum foil.
Heat is conducted upward to the seed tray or soil, creating a warm root-zone environment.

Place the mat under seed trays or pots.
Set the desired temperature (usually 20–30°C for most seedlings).
Turn on the mat and let it maintain steady warmth to promote healthy root development.
