As of Wednesday, October 17, 2012, our lettuce seeds have germinated, which was really unexpected because we were expecting them to germinate in 3-5 days, and they germinated on day 2. Inside the cherry box, we have a plastic container that holds the nutrient solution and an air stone that circulates air. On the first day, the pH was 6.5. We have the lights set up to be on 12 hours per day. On top of the container is foam that our cups rest in that suspends them in the water.
