Plants grown in typical soil are the control.
<h3><u>Explanation</u>:</h3>
The experiment is a process which includes the testing of effects several substances on a known event. Here in this experiment, the effect of salt concentration in soil on the plants are to be studied.
Control is a set of results that are kept for better verification of the results of the experiment. Here the control is kept in ideal or typical conditions and the effect on the plants are tallied with that of plants from experiment.
So the control here should be those plants which are grown in normal soil. Or soil of the environment where the plants are indigenous.

no i did not look it up i just have a that looks kind of like rust
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.
