## 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.)

*by S***E on 15 June 2025*

As good as most of them on the market. If. You've never used 14 propagating seedlings You'll be pleasantly pleased by adding a little bit of favorable heat. Makes a huge difference in the total outcome and the quickness of german ration. Annoying that heat is not a factor mine are on aa Inkbird controller. I don't know how the maths work on On their own I presume I presume they have a thermostat in them. This projecular brand I buy other items for them and they Always have great quality.
