Driftwood can provide interesting architect that no rock can replicate, and is nearly ubiquitous in competitive aquascaping. But I choose not to use wood because it is not permanent as it will slowly rot away. It's a huge investment to groom a master piece of wood with epiphytes only to undo it a few years later. I was considering using fake drift wood, but I am afraid that epiphyte will not root on resin surfaces. Has anyone tried?
