FERRY-MORSE® KHEATMAT-8 Heat Mat, 10 in L, 20 in W, 17 W, 70 to 85 deg F, Black

The mat provides bottom heat, signaling the seeds to begin germinating. Large enough for a standard starter tray, this 10" x 20" mat will work well with any Jiffy seed starting kit. It is easy to use; simply plug it in, and the mat will maintain the optimum temperature range for most seeds to germinate. Designed for indoor use only, it maintains a range of 70-85 degrees. After the seeds have germinated and sprouted, remove the seedling tray from the heat mat and place the seedlings in a sunny window or under a grow light.
