Upon going to the innovation lab, Billy and I were confused as to what we should choose as our experiment. All of the different stations were overwhelming, and it was difficult to decide. After our second visit, we decided that an interesting study would be to see the production cost of the lettuce in system 3. After the initial cost of setting the system up, we thought it would be cool to find how much it costs to maintain the system, and eventually compare this to the production cost on a farm, and see how the cost of bio filtration differs from the cost of fertilizer. We are not yet sure if we are going to be able to create a study that can accurately measure this, but at the moment, this study looks like it will be interesting, and will teach us a lot.
