Spoiler: this experiment is not going to try to grow plants in the lunar regolith.
The "growth chamber" will be a hydroponic set up.
The focus will be on the effects of unfiltered sunlight and all the various forms of radiation that are not present on earth because of the atmosphere.

- cratermoon 2y agoNote that the article says "A nutrient solution was added daily". The linked paper mentions "MS nutrient solution", meaning <https://en.wikipedia.org/wiki/Murashige_and_Skoog_medium https://en.wikipedia.org/wiki/Murashige_and_Skoog_medium>. In other words, the regolith served as a challenging substrate, as long as all the necessary nutrients were added. Without those additions, definitely not.
