I am thinking of using Styrofoam under the substrate and rocks to make a basic shape as I'm going to use only superficial rooting plants like HC, Hair grass and Glosso. This will hopefully safe me a lot of substrate but I am hoping it will keep the substrate from rolling down hill when I place the rocks on it as I want to go ferly high in the back.....
BUT is it possible ...or even a good idea to use Styrofoam in this way?....Does anyone here have a good idea in how to keep the substrate from going down to the foot of the hill(s)?.....How do you guys do this?......should I just use lots of rocks stacked up and wouldn't this get to heavy?
