Quite a setup - nice job! I haven't done much research into exactly how much space would be required to support a family of 2/4/6. This is definitely something I'd like to find out, though. How many are you trying to support, and how many more seasons do you think until it's producing at full capacity?
Looks like you have a great setup there. I like the idea of putting the AgroTowers on top of the drums like that, and that
pump is enough of a monster that height doesn't seem to matter much!
