I built one of these for a co-worker a few years back. It also had to be easy to disassemble. If you don't glue a joint, something could bump or stress the frame in one direction or another and the pipe can come loose from the "tee joint" piece.

The fix is to pick the shapes you want when in storage, glue those joints and then plan for using screws to reinforce joints that you don't want to glue. These stands are usually two flat sides with cross pieces. On the joints where you don't want to glue, use a course thread screw that will go thru the both the pipe and the "tee". This will allow your construction to take a bump and not come apart dumping your plants.
