Re: pennies in hydroponics

What about tossing in a few short pieces of copper tubing which is 
normally used in plumbing?

I suppose that you would have to make sure that the anti-oxidation
coating was removed (with acetone?) ... 

I am very interested in this thread of "super simple hydroponics".
Keep the tips a'coming!
