2-Layer Moss Planter

This is a 2-layer planter for moss I made that has a central large pipe and 4 redirection pipes that are connected to the central one and that distribute the water to the second layer. It works like this: The moss on the top layer is watered, and the excess water pours down and into the central pipe. This pipe redirects the water to also water the second layer's moss, using one cup of water for both layers. I have not tested this planter with anything other than moss. It may not work as well or at all. I do not recommend you try dirt. YOU MAY NEED TO PUT SCREEN MESH ON THE TOP LAYER TO PREVENT MOSS FROM CLOGGING THE PIPES
