Seedfactor MET Certified Seedling Heat Mat with 50?~108? Digital Thermostat Controller for Seed Germination (20" x 20")

Good price, works well for starting my seeds.

I created an under the kitchen counter grow area for my seedlings and my micro-greens. It works pufectly for my small area needs.

Heats for sure but is not the best at maintaining temperature!

I have a seedling mat made by another brand and it's flat and smooth. This made is full of ridges made by the wires going through it. Not a fan of the bumpy mat.

Didn't send the right heating pad. Returning.

The mat never quit heating. It was almost like the thermostat didn't work or regulate the heat of the mat. It did read the air temperature correctly. I purchased this to warm sourdough starter. I set the mat thermostat to 74 and the air around the starter container was over 90 using my thermapen. The starter container was wrapped with 4 layers of towels between the mat and the container. The mat was so hot, I couldn't touch it. When I placed the thermapen on the mat itself, it was well over 100. It cracked my granite countertop under 4 layers of towels. I was watching it very closely and did not leave it unattended. I kept expecting it to quit heating when I turned the mat thermostat down to just above room temp 70 and it still didn't quit heating.

Thermostat setting seems to bear no relationship to the amount of heat generated. Ineffective in jump starting any seedlings/tubers planted. I am an experienced gardener.
