CONCLUSION

In conclusion, our design decision for the hydroponic grow tower system aligns with the requirements and objectives set forth for San Diego International Airport (SAN). The system is designed to use water, natural sunlight, and LED grow lights to create an optimal environment for plant growth. It includes a pump system for water circulation, plant nutrients, pest control measures, and pH management, ensuring healthy and sustainable plant production.

Given our budget of $2,300, we can build three fully functioning hydroponic grow towers. This cost estimate includes the towers, lighting, computer equipment for monitoring and managing the system, outer enclosures for aesthetics and protection, and necessary plant nutrients. With this setup, we can achieve a 277% improved yield compared to traditional methods, maximizing the use of space and resources.

The grow tower's compact and efficient design accommodates the limited space available at the airport, and its ease of installation and low maintenance needs are well-suited for the limited staff available for upkeep. By selecting a cost-efficient model that leverages products readily available on the market, we have managed to keep the project within budget while enhancing its aesthetic appeal through a custom-built enclosure.

With the capacity to grow 96 plants across the three towers, the hydroponic system will support local businesses by providing fresh produce to nearby restaurants and concessionaires. It will also serve an educational purpose, engaging passengers visually and highlighting SAN's commitment to sustainability. This initiative reduces the airport's carbon footprint by promoting healthy, locally sourced food options, aligning with SAN's mission of fostering a sustainable environment.

Overall, our hydroponic grow tower system offers a unique combination of visibility, sustainability, and educational value, making it a fitting addition to the airport’s efforts to promote environmental stewardship and community engagement.
