Growing Broccoli (and more) Vertically

I've grown brassicas of all types in containers and hydroponically for some time.  Now, I want to maximize space and ramp up production.  Saved space equates to being able to grow other things I want to grow in other areas.  Gives me more flexibility to experiment too which is, as you know, a fun thing for me!  So, here I am at it again and this time, I'm attempting more vertical gardening in a new method I'm calling Vertical Brassica Towers.  I've added a video so you can check it out if you like.  Love to hear your thoughts on it.
