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!
I use several heat mats during the winter and Ray is correct, if you don't set the pot directly on the mat, then you may as well not even use the mat. They don't give off enough heat to transmit through multiple layers of material. I'm in Chicago and it gets extremely cold near my windows even with normal indoor heating. Good luck.
