## Questions & Answers

**Q: So just to be clear this is not ul approved and has not safety features , fuses or overheating safety? correct**
A: I just received two of these heating mats. 
Yes! It is marked on each mat "UL approved"

**Q: Can i put this mat in between dirt**
A: Yes, it's waterproof.

**Q: Is it safe to plug it in indoors and use it outdoors?**
A: You can use it indoors.  A regular heating pad you buy at a drug store gets much warmer, so ya it's safe.

**Q: Is the plug safe for outdoor use?**
A: if you mean can rain get in it, the answer would be no.  However, i have this in use in my outdoor greenhouse, though covered by greenhouse plastic.  if you are concerned about the weather, i found this thing at Home Depot by the Christmas lights.  it is a hard plastic tube, that has a soft rubber on the ends, and is sliced in half lengthwise.  you can put a plug down the middle, and close the tube around it making it pretty water tight.  i bought several for areas around my farm with plugs that are outdoors.  This would work if you are plugging into an extension cord.  (My friend uses her heat mats on her covered patio.  not a concern there either.  but, if exposed to rainfall, I suggest looking for that cord cover i described above.  (It is sturdy.  not flimsy.)

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works perfectly!
*by T***N on April 15, 2019*

At first I thought this wasn't even working because it didn't feel noticeably warm. But then after leaving it on overnight under a filled seed tray, I could easily feel the warmth. It's such gentle heat that it just takes a while to get the soil up to temperature, but once it does, it creates a good 15 degrees F or more difference between the soil temperature and the surrounding air temperature. Last year many of my seeds failed to germinate and I suspected that they rotted in the cold damp soil. My house just isn't warm enough in late winter/early spring to get seedlings going. But this product kept the soil pleasantly warm to the touch, and I had seeds sprouting in just two days! Then the seedlings grew like gangbusters in the warm soil--in fact, they grew so fast I had to take the heat away so they wouldn't get too big before it was safe to transplant them to my garden!One tip I learned: the heat is of course going to be highest in the middle of the seed tray, and the cups along the sides that are more exposed to open air will be coolest. So it's a good strategy to plant heat-loving seeds (tomato, pepper, eggplant) in the middle and cool-tolerant seeds (spinach, broccoli, lettuces, radishes) along the sides. Also, since this speeds up germination and growth so much, you might want to plant a little later than you usually would! Otherwise, like me, you might get plants actually starting to blossom in your window in mid-April!

### ⭐⭐⭐⭐⭐ Very happy
*by B***Y on March 1, 2025*

Very happy with these heat mats. I broke the first one (my tray was leaky and I did not know it. It was soaked and stopped working). It initially did work well. I was far more careful with the second mat and it has made starting celery and pepper seeds so far a dream!

### ⭐⭐⭐⭐⭐ Excellent quality and good price
*by J***M on March 20, 2025*

These heat mats are the best there is. I have bought more than two dozens in the past few years. They are still functioning as if new.
