Good Flat Surface Under Seedling Trays, Accurate Temp Control with Ideal Display
Bought VIVOSU Heat Mat with external controller & temp probe to use with Ferry Morse seedling tray & seedling containers. Also using blue & red LED hanging light, not shown Added Ferry Morse humidity dome. VIVOSUN mat under tray. Probe from controller inserted into one container at a time. Display can stay on continuously for easily walking into room & immediately seeing soil temp. Display & controls are very visible & easy to operate correctly. Obtaining very good seed growth due, in part, to good warmth contribution from mat. First bought VIVOSUN mat w/o probe. Controller was not controlling heat accurately. For a test, set to 100 deg F on setting display. Actual mat temp display showed 100 degrees but could touch mat & it was only slightly warm. Also, power cord inside mat, on top, on that mat protruded above overall mat height towards center. Required adding cardboard shims on cord side to have level tray with consistent temperature & light. Returned 1st mat and bought Seedling Heat Mat and Thermostat Combo Set. Delighted with performance of Combo Set!

Quality Product
This heat mat looks and works great. The digital control is easy to adjust from celsius to degrees and can be adjusted to the desired temp for the seeds you are working with. There is a thermostat connected probe that is placed in the planting area and it comes with a small chart that gives you the recommended temperature for the different plants. The water proof mat is easy to clean and is just the right size for my shelving unit.

Works great for 10 degrees above room temperature.
It will raise the soil temperature by 10 degrees over ambient room temperature. For seed starts that require a higher soil temperature this heat mat does its job and does it well. With the temperature probe you know what the soil temperature is. I’m looking forward to having hot peppers to transplant into my garden and have a jump on my growing season. It covers the entire bottom of my seed tray. The temperature in the picture is 79.5 degrees.

Works best indoors
When I received the Vivosun heating mat, I initially set it up in my kitchen and set a small container of pepper seeds on it. I set the thermostat to 80 degrees Fahrenheit, which is a good temperature for germinating pepper seeds. The thermostat did a fine job of keeping the soil temperature to the set temperature. I have no complaints with the Vivosun mat and thermostat. Other purchasers complained that the mat did not lay flat, but I did not have that problem. Next I set up a little propagation station on my patio. I set a Jiffy tray on top of the soil heating mat, and put my planted peat pots in the tray. Once again, I set the thermostat to 80 degrees. Initially I left the tray uncovered. I discovered that without a cover the soil temperature in the tray was virtually the same as the ambient temperature of 60 degrees. I put the plastic cover on the seedling tray, and the soil temperature rose to about 78 degrees. Without the cover, it seems that the heat from the mat just radiated out into space. With the cover on, the unit was not able to achieve a temperature of 80 degrees unless the ambient temperature was about 65 degrees or higher. The mat is low wattage which means that it can only produce so much heat. It is not designed to be used in the way that I am using it, so I cannot fault the product. When used outside, it does provide some benefit by raising the soil temperature by maybe 10 or 15 degrees. Where I live, this can be enough to prevent plants from freezing on a cold night. However, for the purpose of germinating seeds, the Vivosun really needs to be used indoors where the ambient temperature is not less than, say, 65 degrees. Unfortunately, I do not have the space in my small house. I should mention that my pepper seeds are sprouting nicely even if the soil temperature is a bit less than optimum. I will probably look around to see if there is a soil heating mat with a higher wattage. I saw an ad for one from a hydroponics company that appears to be aimed at cannabis growers. Of course that unit is much more expensive than the Vivosun....

Très fiable. Excellent pour starter des semis. Étant dans un coin assez froid, c'est un must pour un jardin productif l'été! Ici l'été est trop court. Pouvoir donner un boost avec ce tapis facile a régler qui a un thermostat pour gérer la température c'est parfait ! ***tomates, piments forts, poivrons***

Exactly what I needed for propagating a few clones. The mat itself is IP67 and seems durable. I can see why this would work well for fermentation, the heating mat is very flexible and just the right length to wrap around a 1 gallon jug. For my purposes I needed a heating mat to warm 4x glass mugs that hold seedling cups (the red plastic kind with removable humidity dome) to propagate a few clones, and it works exactly as I need it to, with temperature probe taped to the bottom side of one of the glass cups to maintain the proper heat for rooting. For the price (28CAD) at the time, its a fair price, although the mat is smaller in person than what the pictures make it seem - like laying 3 phones end to end in size. The thermostat itself would be useful for more than just regulating the heating mat on and off, limited to 1000W according to manual.
