I have 2 of the heat mats that hold 5 flats and a four plug thermostat. Love these! I have used them for over ten years in my greenhouse and are well worth the money. I didn't buy from here but stuebers in Snohomish WA.
The thermostat and one mat. I put the thermostat in a one gallon zip lock back to keep the water out. I grow all kinds of seeps here begonia, petunia and also keep coleus soil warm so I can keep the temp down to 60.
Begonia seed germinating.
I grow lots of plants and seeds on those mats. Water with a hose and water breaker and they have never missed a season.
