Answer:
Oxygen and Carbon dioxide
The biggest issue would probably be number I. The other concerns (II, III, IV, V) would probably be easy to solve with the some specific chamber characteristics.
The fact that the moon has no atmosphere it means that it doesn't retain neither

nor

. Even with the appropriate chamber characteristics to retain such gases, how would the crop in the first place have so much free

to use.
Temperature could be managed inside the chamber as well as accelaration. The period of day light would be long and intense. As for the water, once plants evaporate water when they breath at night (instead of doing photosynthesis), that water could be all collected and condensed by the chamber to be used again during the day light period.
Im not completely sure but I think the answer is Solar Eclipse.
Sorry if Im not correct btw
