I'm surprised the greenhouse isn't larger and/or there isn't significant research there about growing under man-made conditions. I would think for example NASA might be able to use it as a research center while also benefitting the diets of the rest of the researchers there.
If the goal is to research growing in man made conditions then you don't really get anything out of the logistical difficulty of Antartica. The natural conditions are the whole point.
You would also bring value to the inhabitants of the base, so it's not just the gain in knowledge.
