Amazing! I did a test of 45 seeds when it was still a bit cold at night. 15 seeds each 3 different ways, all outdoors. In a raised bed, in tray without heat mat, tray with heat mat. 4 seeds germinated in the raised bed, 3 germinated in tray without heat mat, all 15 germinated in tray with heat mat. The ones on the heat mat came out way sooner and were significantly larger by the end of the experiment. The results were much more drastic than I had expected. Highly recommended.

This mat had worked magic for me. Resulted in almost all my Seeds germinating

Good product, works as advertised and does help the growing process.

The mats work great. I have them set on a timer to control how long they stay on as I cannot tell if the temperature is controlled while on. Looking forward to having plants sprouting up soon.

Great little heating mat.

Works as intended. A bit small. Will buy more if they come back in stock.
