Answer
Dear Farrah,

Sorry, I don't know a way to measure that unless enclose both plants seperately inside an air tight enclosures and measure the humidity levels over time. However, cacti generally speaking save transpiration until night time, when the sun is down and they won't lose excess moisture. Good luck.

Sincerely,

Greg
