Nice looking system Tokie, now I see what you were saying about the removal of the tee.
I'm interested in your advanced line of nutes. I use advanced connie veg (new) for my soil veg tent, and it's working great so far. I'm using GH right now as you know for my rdwc sys, but am greatly interested in how advanced would work in a system like this. I did make a single bucket awhile back with advanced and got a lot of residue, but I don't know if that was due to advanced nutes, or if I cultured a bacteria of sorts. Can't wait for the next run.
