The lettuce is taking off. We will actually have something to harvest. It seems that they do very well in a water culture system. The basil that we planted is not doing so well but it is still alive. We have algae forming in the tank. If we were going to have the system running much longer, it would need a good cleaning. The ph of the system is still around 7. The nutrient solution is still at an appropriate level. Overall the system is working well, mostly for the lettuce.
