...AquaponicHerb! From one excessoid to another, well done! What you're doing right now pretty much describes what I've been thinking of doing in/on a much smaller scale (my living space is very tiny, so quality over quantity must rule the day) ever since I got going... I want to see how well I can simulate a truly natural growth pump in the thing, to get it to live and produce to its theoretical maximum...

And you're already bloody doing it! Hat's off to ye! :tin foil hat:

[but I promise, I'm right behind you..!]
