...whilst browsing 'round de R0n4 last time, was to use 6" PVC or ABS piping, precut lengths, with those 'y' adapters that kinda curve to one side to use to hold the mesh pots (full'o'hydroton), or to just anchor the stem in a reducer, stuffed with foam or a bit of hose or somesuch.

If one slanted the tubing a bit, the roots would grow downwards back to the resevoir, and have a nice long nutrient-film-y place to grow in. Misters would be between every plant pot, and at the ends.

One could theoretically set up such a system for pretty cheap, and tear it down again later, if one was handy... Hmm.... One wouldn't have to spend much bux at it, either... Hmmm...

{Idea might be based on something I might'a saw in CallGirly}
