You're welcome to have a look at what I've done with my hydroponics systems. Check the link below, you'll probably have to dig through the archives a bit to see everything.

Also, you can email me if you want, I'd be happy to offer any advice I have and give you some feedback on your ideas. My email is at gmx dot com, the name is encyclopediahydroponica.
