After researching all the vertical growing systems on the market, I went with the EZ Gro stacking pots. Not only do they offer the most planting sites of all the towers on the market, they are easy to move and maintain. Super simple installation makes them a no brainer for a hydroponic grower. I plan to use them as a stand alone hydro system using AP water from my raft tanks. I will keep posting updates as we make progress.
Randal, sorry.. I just saw the question about media.. I use expanded shale.. all coir / perlite mixes were no good.
