IANAB (not a biologist), nor agronomist, but the phys.org article sounds so optimistic that you'd think the Third Law has just been repealed. ( https://en.wikipedia.org/wiki/Third_law_of_thermodynamics https://en.wikipedia.org/wiki/Third_law_of_thermodynamics ) There's an important difference between 'some plants can perform measurable levels of photosynthesis at extremely low light levels' and 'useful agricultural yields could be obtained under very low light'. Let alone 'vertical farming could become viable'. (Single quote marks since those are not actual quotes.)
