BN-LINK Durable Seedling Heat Mat for Seed Starting 10" x 20.75", 2 Pack Waterproof Warming Mats Plant Heating Pad for Seed Germination, Indoor Growing, Hydroponic, Greenhouse, ETL Listed

This was so easy to use. The temperature is consistent - it does not have a thermostate but this has made my seedlings are spouting and are much happier! The value was great - I shopped around for other heat mats in our local nursury and they were very (VERY) expensive. This is water proof and the length easily covers two of my trays side by side. It is not too thick, seems to high quality and functions as I need it to. Your sprouts will thank you!

Just received a day ago but so far they work great. Temp has been steady, my seeds are germinating. Seem to be great quality and ships extremely fast. No smell, instructions were very detailed but not necessary, very easy to use.

Five stars. So far. They were much less expensive than most seedling mats. However, they are working as advertised. They may operate a little bit warmer than 70 F, but a layer of cardboard fixes that if it's a concern. I am currently using them to grow fodder for my rabbits, and they are doing the job. If anything changes, I'll come back and amend this.

Can only give 4starsat this time because only used them for 3days. But heat is even across bottom of trays and consistent

Works great, just warm enough. I start my seeds inside around mid January. Using 1.5" by 1.5" trays, laid out on a restaurant style sheet pan, roughly 14 rows of 9. Place the warmer on an old bath towel and the sheet pan on the warmer, the towel helps insulate the pad keeping the bottom of the sheet pan warm, but dry. Add a few shop lights. You might need two pads for the larger pan if your in a really cold climate (I live in SC). I'm getting great germation.

Mats work as advertised, they heat up and stay in the proper range. Our seedlings are responding well to the soil temperature. One fyi would be to let them set for a couple days unrolled prior to use so the “curl” comes out before you set individual seed cups on it. If you have a large pallet of seedlings you won’t have to deal with that.

Using it for fermenting kombucha, kefir and other things. Works really well and with a smart outlet you can regulate the temperature if you have a temperature probe.

Maintains a good temp to help seed germination. Cost is negligible. Doesn't have a thermostat but I used an instant read baking thermometer to verify heat output. Temps stay within a degree or two. I've noticed a definite improvement in seed germination. I just ordered the same set of two mats for my daughter!
