Hey Tramble, can you explain to me the specific reasons why you use the planter box? I re-read the thread and maybe I missed it. What are the advantages of this over packing pots together? More soil? More nutrients available because of more soil? Plants bind together so they are held more firmly? Soil doesnt need to be deep because roots can go horizontal more?

I am getting to the point where I need to buy the materials for my new setup. The fact that building a box seems actually cheaper then pots and would ease the watering...Im tempted to go this route.

Thanks for your help!!! (PS. Decided to just go with 4 stationary 1000watt for now and building up to more if I need to).
