Ok, Hello again all ukaps. Im starting to dream up a new scape. And i want to have some nice rocks within the scape, wich is the easy part, But i rely want the rocks to hace green parts to them to look natural. Not alsue thou. I want moss stuck to them growing like you see out and about. Kinda like thouse little mounds off moss you see on roof tiles. Real natural looking. How on earth would i pill this off?? Would HC grow on a rock surface?
