Review: Very nice product and worth the money - Bought this to replace one that I had to return of a different brand. Straight out of the box before I even unrolled it, I could tell it was much better quality. It's sturdy it warms my seedlings perfectly, and it actually works. Which is a big improvement over the last one I tried.
Review: The perfect accessory for making sourdough starter! - This Vivosun Seedling Heat Mat has been a game-changer for me to be successful at making sourdough starter. My kitchen temperature fluctuates too much overnight, so this solved the problem. The heat mat keeps the ambient temperature consistently between 70-80° (usually 76) around the clock. The yeast is thriving. Even though the heat mat doesn't get "hot", I put a heat-resistant silicone mat underneath it as a precaution to protect the granite countertop. I also set the starter jar on a baking rack plus a thin piece of wood to keep it from coming into direct contact with the heat mat. I think it will come in handy when making baked goods that use yeast or sourdough to rise.

### ⭐⭐⭐⭐⭐ Ease of setting up. Works successfully for starting seeds.
*by C***N on April 21, 2026*

I have been germinating seeds with success using these heating mats. There is no temperature control, so no bulky electric cords and controls, but the temp has been working fine for me. I have 3 of these. Once the seeds germinate, I move them under a grow light, and germinate more.
