BN-LINK Durable Seedling Heat Mat Warm Hydroponic Heating Pad Waterproof 10" x 20.75" - 2 Pack for Seed Starting Greenhouse and Germination

I got these heating mats not for seeds, but because I started some ginger plants from tubers. Ginger loves warm weather, but they needed transplanting. It's still too cold outdoors so I put them in a pot and kept them warm with a heating mat. My ginger has been thriving by the patio door where they will be until warmer weather arrives. They have doubled in height since I put them on the mat.

These have done a great job at warming the soil in our trays to germinate seeds. We've had a very high germination rate this year after adding the seed starting mats so I know that the extra warmth has made a difference. They have worked flawlessly, keeping a nice warm temperature and are well made and sturdy.

I have several of these mats in several different sizes in my basement growing room, and they are great and help with germination of my little baby seeds!

Heated up very fast, I also bought the seedling starter trays with the domes, these heating mats have already started the plants humidifying! Great product

These keep a good temperature and when I used these this season, I had 100% germination on my tomatoes. They are the right size to fit under the Jiffy brand seed starting trays too. They come in rolled up but flatten out quickly.

Two heat mats! I use one to proof yeast and raise dough for baking. And the other is getting seedlings ready for spring planting. Temperature-wise the rooms I use these in are around 58F, it being February. The mats stay around 80F.

Great product great design works flawlessly great seating starting great transplanting options works really well. I would recommend this to anybody who wants to start vegetable or flower seeds from seed.

This was my first year of propagating seeds for the garden and I needed seed heating mats. These worked great. I definitely would recommend these and purchase these for myself again.

The seedlings did start to grow with these heat mats, but there is no temperature control. If it could be turned up that might make it a quicker process.

It's hard to recommend a product that doesn't live up to expectations, but I'm also not going to recommend it because I don't like the way I set it up. I have no idea what temperature it's set to. It would be very helpful to adjust the temperature though. I put it under my pepper plants and none of them survived.
