Agree with your comment with the caveat that growing the plants on the Moon would probably provide useful locale-specific information on the amount and strength of sunlight, received radiation, etc. The always Earth-ward face of the Moon has an electromagnetic spectrum environment that is different from the earth-orbiting space station.
On a completely silly note, I am glad to see no kudzu seedlings are in the experiment. Not a pleasant thought to imagine discovering that species could survive on the Moon. Even worse if it escaped containment.
Yes, but what about the long lunar night? 354 hours of darkness. I don’t think the plants can survive that without man-made lighting.
