Review: 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!
Review: 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.

## Questions & Answers

**Q: Anyone use this on a 20 gallon long tank for a leopard gecko???**
A: I use mine to heat my 29 gallon reptile aquarium. Get the thermostat for it because these mats run at about 100 degrees without it.

**Q: can you put splitter on controller and run multiple mats?**
A: You surely can, the 1020 mats are only about 20 watts each.  What you need to watch out for though is after you get various brands of mats.  They are not equal.  Some run hotter than others.  If you place your temperature probe in a tray on a hotter mat and set it to 85F, one of your cooler mats may only  be maintaining around 78F.

**Q: What do you do to get this mat to lay flat? Mine seems permanently creased and bent from its shipping position.**
A: I had to put something about the same size on it for a couple of days to get it to lay flat. Even a piece of wood with a weight on it would work, about 5 pounds is all that's needed. Hope this helps!

**Q: Can the probe be left in the air to read temperature? I'm trying to keep an enclosed container warm at a set temp.**
A: Yes, it can read room temperature, however it's the soil temperature that helps the seedlings grow. Also, I believe  when it reaches set temperature it has a delay before turning back on. So use sand or rocks to retain the heat longer.

### ⭐⭐⭐⭐⭐ Works great for 10 degrees above room temperature.
*by J***T on January 4, 2026*

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.
