Fresh Water

On April 17 we decided that our system was in need of nutrients and fresh water. We pumped out about 4 gallons and put the nutrients and pH down in each gallon to ensure that our plants were receiving what they needed. The temperature of the water is still steady around 71 degrees even though the lettuce does prefer cooler temperatures. It is difficult for us to maintain cooler water temperatures because we do not have control of the room temperature. But with the fresh water and nutrients, our lettuce continues to grow and is about 5″ tall!

  1. I like the picture with the ruler. That makes the size very clear!

    Didn’t you tell me that you changed the nutrients? Be sure to document any changes that you make.
