Keimlings-Heizmatte

Finally got my tomato seeds to sprout in three days instead of two weeks — that 7-degree bump makes a real difference. The mat is thin and unobtrusive, fits perfectly under two standard trays.

My greenhouse stays around 15°C at night, and this mat brought the soil up to a steady 22°C — that extra 7-degree boost made all the difference for my lettuce germination. Plugged it in, spread it under the trays, and within two days I had tiny sprouts poking through.

I was skeptical about how much difference a few degrees would make, but my pepper seeds sprouted in just four days after I set this up. The mat stays consistently warm across the whole surface, and it's thin enough to fit perfectly under my standard nursery trays. Very pleased with how well it works
