aero

hi just a couple of questions just in the process of getting the bits and designing the grow room.
when plumbing the garden can you use copper pipe?
would it still be advised to use an air stone in your reservoir?

I would not use copper because the moist air will cause it to patina. Use vinyl 1/4" i.d. (inner dimensional) tubing. You can get 15 feet of it at the hardware store for $3-$5. Use the airstone/rod. The AG pump is weak sauce.

I second what he said. I also heard you don't want copper in or around your grow due to toxins etc. Why risk it? I'm also doing an aero grow. Check it out.
