This Seedling Heat Mat Starter speeds up germination of seeds and gives an improved success rate for growing seedlings. Ideal for vegetable and other types of seeds, this 10-inch by 20-inch mat provides warmth at the root zone, giving your seedlings an excellent start in life. It comes with handy instructions printed on the mat itself so you'll never lose them.
The plant heat mat automatically keeps seeds and roots consistently warm at 10 to 20 degrees F higher than the ambient air temperature in your growing room. Place the mat on a dry, flat surface (not plastic) and plug it into a 120 volt plug outlet. The mat is stain- and water-resistant, and it's UL listed, giving you peace of mind. Set your seed flats or trays on the mat and watch your seedlings sprout in much less time than they do when unheated.
Using a plant heat mat allows you to grow more seedlings for transplanting into the garden because they sprout much sooner, so your turnover is increased. Heat mats can also be used to culture yogurt, kombucha and kefir or to ferment sourdough.
