Review: Worthwhile purchase - Worked as descibed. Well made. Improved germination.
Review: Great for sourdough starter if it's cold in your house! - I don't use mine for seeds. I make my own sourdough and especially during the winter months, this helps my starter stay nice and warm, if I'm going to bake. I just loosely wrap it around my starter jar, on the lowest setting, and my starter grows nice and fast! Definite must-have, if you're trying to start a sourdough journey and are having trouble with cold starter.

### ⭐⭐⭐⭐⭐ Worthwhile purchase
*by S***S on January 19, 2026*

Worked as descibed. Well made. Improved germination.

### ⭐⭐⭐⭐⭐ Great for sourdough starter if it's cold in your house!
*by A***E on September 8, 2025*

### ⭐⭐⭐⭐ Nice Cheaper Heat Mat
*by I***E on April 3, 2023*

First of all I love the price of this - it was the cheapest I could find for a seedling mat. The heat output was great for my seeds, but I would definitely recommend buying a thermometer in conjunction with this to figure out the temp you need. The temp dial is a bit finicky and hard to get precise, hence the lower rating. But despite this it still worked well for my seedlings! For the great price I would recommend if you're willing to spend the extra time to figure out the dial.
