Finally a positive subject, it's nice! We can guess that the basic problem will be less an agricultural problem than an infrastructure engineering problem. We need water, a temperature without too much difference, a gas mixture not too far from the air neither by its composition nor by its pressure I suppose.
On the moon, the nature of the soil not being very far from what we have on earth, it should be able to supply the minerals. Then there is the problem of lighting, provide LEDs. The lunar day being 29 days, not sure that all the plants support, and probably not the 15 days at night.
The solutions to be implemented therefore risk being very close to urban farming techniques, once we have obtained the airtight room and the water, which risks being the bulk of the job (note something interesting: no need for glyphosate to prepare the ground).
