I just purchased a windowsill heat matt by Jump Start
that is 20'' x 3'' and I' having trouble finding a plant
tray the correct size to sit on top of it. Does anyone]know of a source or a solution to this problem?
Found a site for you...plastecproducts.com.Scroll down to bottom and click on "saucers". The oval shapes are what I have but cannot find them in stores easily. Hope this helps!
