I think anubias could grow, slowly, with just the natural light in a house.
Egeria densa, is really, really undemanding, it did grow up like mad in my low light tank.
A lof of crypts are quite forgiving.
Ceratopteris thalictroides too, in my low light tank, was growing like mad and doing baby plants all the time, and it was rooted to the bottom, not even floating.
Maybe it was already told, i did not look at all the posts.
However i do have some issues with some plants in the list in post no. 258.
Bacopa caroliniana is not a low light plant, it will just grow leggy and ugly, if at all.
Bacopa monnieri too.
Hygrophila polysperma was struggling in my low light tank and i lost it.
Same for ludwigia repens, struggling, ugly, full of algae.
Rotala rotundifolia same as ludwigia repens in low light in my tank.
Cabomba caroliniana requires a minimum of light, hardly a low light plant, limnophila sessiflora would be better, less demanding, and the look very similar.
Hydrocotyle leucocephala, yes if floating but not floating in low light, it did die.
Riccia fluitans, floating yes, not floating i doubt it.
From my little experience for what it is worth. My low light tank was a 24" high one with one led fixture Beamswork third generation (121 - 0,2w leds 10000K). It did ran for 8 months.
Another issue maybe the perception some may think their low tech tank is low light while they effectively have medium or higher light.
