This is the Fast Plant continuous watering planter made out of an empty 2-L soda bottle, a sponge, and potting soil. The label was removed from an empty 2-L soda bottle and the bottle was cut into two piece. The bottle was cut one inch below the point on the neck where the curve became straight wall. A sponge is cut into a square rectangle and inserted up the neck of the bottle. The top section of the cut bottle is filled with potting soil.
