Growing Greens Vertically

I really like the idea of growing things vertically as you can probably guess.  I am noticing, anecdotally, that plants prefer to their normal upward growth patterns.  Over the years, and in several instances, I believe I see plants stressing when trying to overcome growing sideways or upside down.  Their inclination is to seek the sky.  I first used the towers and attempted lettuce, turnip greens, broccoli, onions, spinach, and strawberries.  The strawberries did ok and the onions were marginal.  The rest did not perform close to expectation.  So, let's see if I can put wicking in the vertical towers to good use with this new modification intended to give plants more space and allow them to grow in their normal habit.  Check out the video:
