Perfect seed starting mat for Northeast Ohio

I am currently using this mat right now under my tomato, luffa and pepper seedlings. It makes it so much easier to maintain the temperature since I started them so early. A friend of mine said they may purchase one to control her sourdough starter temperature in the winter for our area

Keeps seedlings warm at night!

I ordered this by accident but I did need it so I kept it. Use it at night to put my seed cups on to keep them from being wet %26 cold. These watermelon seedlings are doing great. Last year they grew horribly. I'm trying to keep them warm this year till the ground warms up!

Happy first timer

First time using a heating mat. It works. Kept on and did check the temperature of the soil. I got faster germination for some seeds (cantaloupe, alyssum, cucumber, basil, lemon balm, bergamot, big Thai peppers, sweet peppers popped up within 3-7 days) while other seeds (marconi peppers, daisy, coneflower) seemed unphased by the additional heat. Either that or the seeds are bad.
