Indoor plant fountains bring the beauty of plants and the soothing sounds of flowing water into your home. Building your own plant fountain can be more economical than purchasing one, and it allows you to be far more creative, selecting the plants and stones you prefer. You can even choose materials from your yard or from your local area to create a more personal fountain. Once the materials are assembled an indoor plant fountain can be constructed in one to two hours.
Test the pump and set the water flow at the desired rate. Fit tubing onto the pump's outtake valve. Cut enough tubing to reach the final height you want the fountain to be. Place plastic container over water pump and cut holes where electric cord and tubing need to pass through. Using a container will protect the pump from the weight of the rocks that will cover it.
Place pump in the base of the waterproof container and place the plastic container over the pump. Place the largest rocks in the base of the waterproof container around the pump or use pieces of PVC pipe. The PVC pipe can be less expensive (especially if you plan on buying rocks) and will reduce the weight of the fountain (a plus if you ever want to move it). Make sure the tubing passes through the larger rocks or PVC pipes.
Cover the rocks or pipes with a piece of window screen cut to fit inside the container. The screen will filter out any debris that falls into the water and keep the pump from getting clogged. Cut a hole for the tubing if necessary. Cover the screen with a mixture of larger rocks and smaller pebbles to reach the desired height. Plants (in their own leak proof containers) can be placed on top of the rocks or around the outside of the container. Do not place plants directly in the fountain, because they can clog the pump and the chlorinated water is bad for them.
Fill the base of the container with enough chlorinated water to cover the intake valve on the water pump. Add the copper elbow to the end of the tubing and arrange it among the rocks at the desired height. Check the direction of the water flow and look around the container to make sure no water is being directed over the sides. Rearrange the rocks as necessary.
Use a large rock or plant to disguise where the cord emerges from the container. Plug the pump into a grounded outlet. Always unplug the fountain before adding more water.
