Today we came in after the weekend and checked on the system. We discovered that there was some minimal algae growth in the upper tray. We took the upper tray out and cleaned it. The next thing we did is moved some of our smaller plants forward to get some better light. The final thing we did was to add more nutrient solution to the system and then lower the pH back to 6.0.

Today we came in after a week of not being in the lab and noticed that some of our plants were looking a little droopy. We believe that the droopiness of the plants can be attributed to the amount of time the plants have gone without fresh solution added to the system. Also we discovered some algae that had started to grow. We cleaned out the tank and added fresh nutrient solution as well as checked and lowered the pH to 6. The growth of our plants ranges from 4 1/4″ to 6 3/4″. We are very pleased with our progress and are hoping to continue to have excellent growth. 
Day 6: 11/2/10
Today I came into the lab and discovered that our system had evaporated some of the nutrient solution. There was no sign of settling with the solution. I added two gallons of the nutrient solution to the system and then checked the pH which was around 7 and then lowered it to 6.0. Also our plants have some excellent growth.
