Seedling Heat Mat 480



Seedling Heat Mat 480 is designed to work with any 25 x 50 cm (10″ x 20″) seed starting tray. Supplies bottom heat to give a “jump-start” for all your seed starting. Creates a warm growing medium environment to improve seed germination and encourage faster growth. Specifically designed to raise rooting area temperature to approximately 23°C (74°F).

Heating mats are shipped rolled inside a protective plastic sleeve and cardboard box. After opening, gently flatten the mat (unplugged) in a warm room. The plastic base retains the rolled shape until sufficiently warmed and persuaded to flatten. Flattening may require weighing down overnight in a warm room. Books make ideal weights.

Keep out of reach of children and pets. Place the heating mat under the propagation tray (not in it). We recommend using a ground fault circuit interrupter (GFCI) outlet.

UL approved 17 watts, 120 volts.
