Your wish is my command!
It's actually potted in a smaller plastic square pot inside the clay pot. I just moved it back into the tank, cause the spike now actually fits. It seemed to do okay at ambient 30% humidity, although it did blast a spike and looks like it wants to blast another.
I'd say this spike fully extended is just a little over 2 feet long!

Strange - it has another spike that's only 6" long and the first time it bloomed, the spike was only 8" long.
