I am glad to say David and I are making progress with our hydroponic system! After measuring our mesclun, the tallest plant measured out to be two inches. The other three varied in height below two inches. However, our plants do not look the healthiest right now. I am not too worried at the moment unless I see anymore signs of the plants getting worse. David mixed more nutrient solution and we exchanged that with the old. I thought this would be a good idea since the nutrients had settled on the bottom, again, and I wanted to make a fresh solution. We are still not up to the size as the other groups have with their plants, however, I am satisfied with our progress we are making since our downfall we had in the beginning. Things seem to be looking up for David and I.
