I got these heating mats not for seeds, but because I started some ginger plants from tubers. Ginger loves warm weather, but they needed transplanting. It's still too cold outdoors so I put them in a pot and kept them warm with a heating mat. My ginger has been thriving by the patio door where they will be until warmer weather arrives. They have doubled in height since I put them on the mat.
