Method of use：
After heating the product to around 40℃, place the seedling pot or plant on a mat. By isolating the temperature at the bottom of the flowerpot, the temperature emitted from the soil is just enough to promote plant growth.

They work great. I bought a bunch and put them under seed trays. Well made and big.

Purchased these for our plants when starting them and when bought inside for the winter. tested them upon delivery and all heated up nice and evenly. Toasty, too. Highly recommend them. Can't wait to use them.

Without any previous experience with heated mats for starting seedlings, I must say I am quite delighted with their performance.

Heat mats work as expected-- great quality! I have left these heat mats on 24/7 for my seedlings without issue and work as described. Love the multipack for great value!

These were not what I was expecting..... But lets start with the good... They heat up. I put 4 of these on my controller with 2 - 2x4 foot heat mats and the controller handled it, so I can assume the wattage isn't much different than other brands, however, wattage is never mentioned in the Ad.Ok..... thats it for the good......The bad: when they mentioned in the ad the difference in size measurements, one could assume they could be 1/4" smaller or bigger..... 10x20.75 is a pretty standard number. But the are 9x18 1/2 Way smaller than just a little bit on the length. Seller could be honest about this and NOT advertise a measurement that it does not meet or come close to.The other stuff they don't tell you in the AD, but is on the box they come in is that it will only heat 10 to 20 degrees above room temp they are in. So if its 30 degrees in your greenhouse, it can only get the mat temp to 50 degrees, which isn't warm enough for the roots in most plants and trees.They are thick padded mats. I put one down on my level bench, put a tray on it and started putting water in the tray. I had almost 1/2 of water on one end of the tray before the other end got wet, so these are not good for water trays your gong to put seedlings in.Because the mat is padded in some way, I feel they are not as durable as the other mats I have. Its pad and heating element inside a sealed soft vinyl cover. Im not an engineer by no means, but they feel like this will be an issue with ripping/tearing/cracking.The other thing to consider, which is inconvenient for me and i did not think of it when i ordered these, is the electrical cord comes out the side of these. so if your bench is 20" deep and you lay your mats side by side, your now going to have a cord in the way.I will more than likely be sending these back since they will not reach the temperature needed to keep plants alive when its cold.

Great for germinating my seeds indoors.
