BN-LINK Durable Seedling Heat Mat for Seed Starting 10" x 20.75", Waterproof Warming Mat Plant Heating Pad for Seed Germination, Indoor Growing, Hydroponic, Greenhouse, ETL Listed

Works as expected! My seedlings are already popping up in less than a week. It doesn’t automatically shut off or have a timer so I just unplug it at night. It doesn’t get too hot but I do have it on an area made of wood.

This worked great with some older bell pepper seeds that wouldn't sprout no matter what I tried! I used the last of the seeds and 7 out of 10 sprouted and are growing well in my greenhouse, waiting for spring.

THESE ARE AWESOME.... KEPT MY SEEDS WARM ENOUGH TO POP!! NICE!!! GREAT PRICE TOO!!!

I saw other people using these mats for their sourdough starter, so I got one. It’s way too warm to be using it for a sourdough starter. I already chucked the box or I would return it since I don’t need it for anything else.

My pepper seedlings love this mat, definitely seems to give them a boost. Gets warm but not too hot.

I actually use this heat mat for my kefir and sourdough starter, and it’s amazing! Keeps a consistent gentle warmth, which helps my ferments stay active even when my kitchen gets cold. My starter bubbles faster and my kefir thickens beautifully overnight. Easy to wipe clean and the low, steady heat makes it foolproof for small fermentation projects. Total game changer!

Initially this worked well. It’s a pretty good price and holds itself at the proper temperature for sprouting plants. However…it went bad after a couple years, stopped heating. It is waterproof, so that’s nice.

I purchased the four pack. At $10 each, this is a great purchase! Do the math. 10 to 12 plants can yield a 100x return the first season. I live where Winter and Spring take turns from April to May 14. Starting early with a heat pad makes for strong starts that go in the ground on Mother's Day. Combined with my small high tunnel, May 1st means I am starting up the trellis!
