[Market-farming] Bench heating in greenhouse

We have a wood gasification boiler that we use to heat water, we run 
the hot water through half inch pex tubing that is layed out on the 
greenhouse tables and we put the flats right on top of that.  It 
keeps the flats nice and warm and it keeps the greenhouse above 
freezing and since we have a wood lot, it does not cost money to heat 
the seedlings and the greenhouse.

The gravel sounds like a nice touch to it but heavy and while it 
would  add to the system I wonder if it would be necessary.  What we 
do (three years now) works.
