Here are the couple of pictures I said I would post. Here's what the frame looks like naked. You can see that the work-around on horizontal and vertical pipes is to stagger the T connectors. I put one piece of vertical pipe in to show how you would go about adding a second (or even third) shelf. The nice thing about working with PVC pipe is that you have a lot of flexibility in how you design it.

I've also included a picture of how to join the pipes and connectors with panhead screws if you have a drill and a mind to. You really only need to use screws as a precaution if you're planning a fairly heavy load (potted plants). You relaly wouldn't need them for seedling trays, and maybe not even for the potted plants - it's just an option.
