My mess of roots. The main one in the middle is from my big tomato plant. It's hard to tell from the picture but there is about two inches worth of roots in the bottom of the tank. It blows my mind how expansive the root systems get and how much mass is accumulated in the bottom of the hydropnics tank.
Need to get harvesting these tomatoes! If I remember in the morning I might take a few to work to bribe my co-workers with. Tomatoes are the best bribe right?
