Finally decided to remake the walls. (sorry for the messy plant groups)

I'm using coral moss on the back and right walls, phoenix moss on the left wall.
This time I'm too lazy to make the moss tiles again so I just sandwich the the moss between to pieces of plastics mesh.
I've done this before but abandoned this method because it took too long for the moss to grow out of the mesh. Dennis Singh actually reminded me of this method during one of our facebook chats >

.
One benefit of this method is that, once the coral moss sticks out of the top mesh, I can just separate it from the bottom mesh and use it to make another moss wall.
This creates an infinite supply of coral moss since I can just keep removing the moss from the mesh every 2 months and it will always grow back.
Getting the king of erios (Matto Grosso) ready for the next scape >
