I have a growing stand, 3 level, that originally came from Park's. We just went to put it together only to find that 2 long pieces are missing, and are most likely packed away in our POD. It is not at all possible to retrieve them until we complete our move in the future. So I dug out the paperwork and found that Grower's Supply made it. Their # was no longer in service, but I found another on the internet and called. That too, was no longer in service, plus they don't sell to the public it said. I called Parks but they were unable to help me. Anybody know of supply stores that will sell just parts to these things? I have the screws, oddly. It is just the middle poles that are missing.
