## Questions & Answers

**Q: How much watts and amps does this pull?**
A: Watts (power) = Amps X Volts
Description says matt requires 105W in power/energy to operate
Common current in the US is 120V
Just Solve for X      W= ? X 120   --->    W/V equals A
105W/120V =  .875A

**Q: Can you use a thermostat with this?**
A: So far out of four AC Infinity Suncore mats  [2X 48x20] [2X 20x20] THREE mats overheat my seed trays.  I've lost FIVE 72 cell trays all seeded.  Puzzled by NO germination, I used a meat thermometer and the readings in three of the trays was 95-100*F and the fourth was 75*F.  Either AC Infinity Suncore mats have zero quality control or the overall quality is POOR.  Be aware these mats will bake your seeds killing the seed germ.  If you have them use a probe thermostat.

**Q: What temperature is L M H?**
A: Put your seed tray under a grow light, preferably with a dome. Then lay a thermometer underneath the dome on top of the seed tray. Then turn the thermostat to medium; Wait for about 6 hours and see what the temp. is.In my case it was about 85 degrees ; I then turned  the thermostat between low and medium and it went to 82 degrees.( I put a piece of insulation between the wood shelf and the seed mat.) My seed tray is in the basement; The air temp. is 67 degrees .So the mat raised the temp in the seed tray about 15 degrees. Now, I hope I have good germinating seeds.

**Q: Can this be hvac taped to the back of a terrarium for inside ambient heat?**
A: I would not that's not what it's for.
