Week 9 Progress (Completion)

The constructions were finished this week. The hydroponic system was modified. The finalized schematic is shown in Figure 9. In stead of letting the water flow back to the reservoir from the bottom, a block is added in the middle of the left bottom pipe to block the flow of water and a tube transfers the water back to the reservoir. This modification facilitates the water flow by adding more potential difference of the water level on the two sides; however, the lowest two lettuce places are given up due to the addition of the block.

All the parts of the planter were put together, and the plants were installed into the planter. The final module is shown and annotated in Figure 10. The hydroponic system was tested and the plants were being watered. The planter is a success.
