When I used them, I used them as aeroponics chambers. I put endcaps on the pvc and drilled holes into which I ran a 3/4" pvc spraybar (pvc with a bunch of tiny holes). The larger holes in the large pipe held mesh pots filled with Hydroton media. I ran a powerhead from the fish aquarium into the spraybar with a return. The fish poop water sprayed through the bar, aeroponically saturating the plant roots before draining back into the tank. Mine was not set up long enough to determine longevity but it worked great while I had it set up.
Elevation 300ft. Expanding clay soil.
