Works great!
I ordered this to germinate some scorpion pepper seeds that I harvested last year. Scorpion pepper seeds can take weeks longer to germinate and may not germinate at all without a heat pad. My seeds had an over 90% germination rate after only 7 days on this heat pad.

5.0 out of 5 stars Quick germination
Reviewed in the United States on March 15, 2024
This mat is so helpful when starting your plants from seed. It helped maintain warm soil in the cooler temperatures of my home during March. My seedlings usually take a couple weeks to germinate and pop out of the soil but I used this mat from day 1 and there were some seedling popping out within 36 hours. Photos are from day 5. This is also the highest germination rate I’ve ever seen in my starts. I’m never starting seeds without a heat mat again.
I used the organic Jiffy seed starting mix in empty jiffy trays.
