Day 2: 10.19.10

Today was the five day mark after we planted our seeds and two had already begun to sprout and were petruding from the rockwool about half an inch to a inch.  Due to the nutrient mixture, there was a small layer of film sitting on top of the water in the system.  Due to the quick success of the system we opted to not make any changes to it and we would see how it would fare during the next class period.

Day 1: 10.14.10

Today was the day in which we finalized our hydroponics system and planted the lettuce.   Ten seeds were planted in a single block of rock wool and the system will flood for fifteen minutes with a fourty-five minute break.  It sits under the light which travels continuously on a horizontal path.
