This is my most recent project. I started out as a aquarium made from 2 litter bottles. This is a aquaponics garden. It uses 2 litter bottles and a few other parts that are very easy to find. A pump is used to pump waste from the fish habitat to the plants housed in the 2 litter bottles. Every thing is supported by a wood frame. At the moment it is only 2 parts. The Double female adapter lets you connect 2 bottle together, the filter lets nothing but water escape the system, and the over flow adapter keeps a level water level.Print each piece with 20% infill.
