Has anyone ever tried making a moss wall? I found directions for this on the interweb and am ready to give it a try. I have done all the expanding foam stuff in aquariums but I think it eventually does more harm than good not to mention it shrinks up ALOT even when it fully cures in an empty aquarium. Thats just my humble opinion. I don't mind talking about that too as I'm sure I still have much to learn ;0) Thanks.
