Day 1 – 5/19/2011 – We have successfully completed building our bubbler hydroponic system. We used a fish tank as our container, we used Styrofoam for our flotation device, and we placed five cups evenly across the Styrofoam. We used Rockwool for our germination process. We are growing Mesclun which is a type of lettuce. We checked the PH before we left today and it was at 5.0 the perfect reading for Mesclun lettuce. We hope to see some kind of improvement next week on day two.
