Sprouting tray with water reservoir

The model consists of a water reservoir, a tray for the seeds and two different caps you can easily screw onto the tray. These caps either have, or don't have holes. You can choose which ones to screw on to match the water uptake with the needs of the plants and evaporation. 

The tray can be filled with cotton, paper or other material that absorbs water. Seeds are layed on top, water can be added to the opening on the side, and after al that is done you can wait for the seeds to start sprouting.
