        I've been starting seeds for several years. Since I have gotten these heating mats. I get higher germination rates and what seems to be stronger seedlings

              I use it to keep soil warm in starting seeds, nursing transplants, and recovering sickly favorites. I have not found a 'down side' to the product. My adult son saw it and said, "Where can I buy one of those!"

                            we are new organic gardeners and rely on others for LOTS of advice. This item was recommended and we purchased two. Our seeds started to grow within three days, and we are really excited to start planting on Memorial Day!

                              This is a great product to extend seed germination in our cool, rainy Spring! The added warmth is a must to start seed germination since it has been so cool and rainy in the Northeast.

                              Seeds on the heat mat germinated quicker, no doubt. Worth the investment.

                                  My entire family has been amazed at the quality and size of heirloom tomatoe plants started from seed. My sister started seed using the traditonal method and had 1/2 the amount of germination. My plants are probably twice the size of hers. I'm looking forward to the garden season!
                                  Thanks also for the online videos and instructions. Made a copy for my sister.
