Great heating mat
So this has been used for a dual purpose.... 1. Great for starting my seeds in the colder months. Excellent! 2. Had it keep kittens warm after being born, obviously put multiple towels over it so its not too hot for them but it worked great! So whether you're using it for seeds or using it for animals it works 👍

My go to growing pad
Did you know that your seeds like heat and it helps them to go? I did not. This was a game changer for me. It was worth the money and worth. Very durable. I will be able to use it for all my growing seasons.

Bread making essential
I use this heat matt to assist in bread proofing. It’s been a game changer, excellent, consistent results. I do tend to put it on a wooded bread board rather than directly on cold stone work top. Currently used once a week for over a year and a half and still works like new. 100% recommend, and great value for money.

Good
Maintains a consistent temperature for seed trays. Adapter runs a bit warm, though not enough to concern me as a fire hazard. True to size.

Plant health
Awesome little heat mat. I got this for my key lime tree that is indoors. It was struggling to wake up from winter and I threw this under it and it absolutely took off. Pretty simple but highly useful. It’s been a couple moths and as of now it’s still doing it job just fine.

Quality Heating Mat For Seed Starting
This heating pad is excellent for seed starting. I'm getting way more success in seed germination since I bought this heating pad and began using it. This is the second year of using the heating pad and I've saved enough money to pay for it -- not having to buy starter plants. I expect I'll get many more years of use from the heating pad as it seems well built and provides a consistent heating temperature. Great product.

Gut und günstig
Die 20w sind perfekt für Pflanzen Aufzucht. Sie wird nicht zu heiß. Man braucht aber definitiv einen Regler mit Temperatur Fühler dazu.
