You are not going to find alot of people here having planted tanks with the foam as a background. Most people want as much room in there tank that they can spare for the plants. You may want to swing around to some chilcids forums as alot of them have used it before in there. I attempted to create a vivarium out of the stuff and it was a PITA working with. Hard to mold and really stinks b ut you may have better luck with it.
