Good value and very helpful for germinating seeds
We start a lot of vegetables from seeds and these mats have been very helpful. We have several and have had zero issues with them.

Warming mats that are simple, effective and priced right!
Good product. Purchased for my wife who is starting plants from seeds. She says the heat has helped them grow 2-3 times faster, even in an indoor environment. Check the dimensions carefully. You may wish to buy two for large trays. The mats are warm, not hot, which is what you want.

Very Impressive
May not have a temp control, but works really good. Sprouted my seeds in 18 hours. But prepare yourself a sprouting container with tape to seal out the light.

Product works as intended but don’t expect it to solve all your seedling problems
This is my second season sowing seeds so I can’t say for certain why I got low germination rates but this product didn’t seem to help as I would hope.That being said, the product works fine and provides stable heat. It fits my growing tray well and is super easy to set up. Smells fine too.

Long and not wide or hot but works. Perfect for seed germination
Pretty long but not wide at all. I used to to keep my pacman frog warm as a tiny baby. Ill save it to help hatch silkworms next.

Great for starting seeds
I have used these for several years to start my seedlings in my grow tent in the spring. They really help!

New Sprouts in record time!!
Solid mat to use to germinate seeds. Pick a good location preferably in door with a surface that wonât absorb heat. If needed put cardboard underneath to insulate. I got great results in an accelerated timeframe.

Good Heat Mat
This heat mat works great for seed starting. Iâve got dwarf Schefflera seeds and Christmas cactus seeds germinating now. Already sprouted asparagus fern seeds.

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

EDIT – Sorry, I reviewed the mat and the Vovosun Thermostat Controller at the same time! The mat by itself gets too warm without being controlled by a thermostat controller.I wrap this around the bottom of the bottle and stick the probe onto the bottle about half way up. It keeps the temperature within a half a degree to a degree according to the thermometer and it seems pretty accurate when checking with the temp strip on the bottle. It’s working great and will make kombucha making much easier through the colder months!

Great product. Comes sleekly packaged. Heats up fast and hold temps for my seedling throughout the cooler evenings. Its a perfect size to fit a full tray for seedlings. Temps appear to stay fairly constant as I have a thermometer on it. My greenhouse creates a lot of humidity so its great that the mat is water resistant.
