I'm not sure why people who believe in organic growing use PVC but I do not for multiple reasons. I bought galvanized pipe and it didn't seem to matter that it was less than 1 inch thick. I'm really glad that the company cares about it's customers and their projects because I was almost without a bed and later into the season and the seedlings needed their space but the company came through for me and I appreciate the customer service team taking care of it! I have tons of corn packed into one and did the pipe all the way up to 7 ft in the air so that things can trellis up as well. Another plus with the galvanized metal pole is that nothing comes out or moves, the thing is the sturdiest I have in my garden.

Got this to try out as an alternate to building wooden raised beds. The construction of the bed was easy and I skimmped a little and used 3/4" pvc instead of 1" and so far it is holding up like a champ. I ended up gluing the sections that used the slip-Ts since they kept falling out. You could also use 3-way connector at this point and you might get away without having to glue. After building it, I thought you could also add a slip-T at the corners to make a frame for adding some Agribon or greenhouse plastic. All in all, I am very pleased with this product and may purchase more. One note, before filling it, make sure you have all the supports lined up straight.
