sounds like a good plan..........You want to wrap them in newspaper and put them in a box where they wont be rolling around, if its only an hour away then the plant really shouldnt suffer. Just have its space ready when it gets there so you dont interupt the 24hr photoperiod too badly.
Roll the newspaper around the pot corkscrewing upwards like a spliff, tape the corner on top over the top of the plant. This should provide protection while they travel.
