Nan, did your heat mat come with a thermostat?  It is easy to "cook" plants
with the bottom heat too high.  I never set mine higher than 70 and be sure
to use a soil thermometer.  My mat came with very specific instructions as
to how it was to be set up.  I put 1" styrofoam sheeting over my GH bench,
covered the styro with the mat, covered the mat with hardware cloth, and
covered the hardware cloth with 6 ml. plastic.  The ground wire is attached
to a metal rod in the floor.  I would follow the instructions that came with
your mat to the letter since you are mixing electricity and water.  Marilyn
