I have one Planted+ on a 20.5" deep tank (36 bowfront) with 2" of substrate. No other lighting. It is deep, but not quite 24" deep.
I'm planted with all of the above, except I have no dwarf sag. All of the plants all seem to being doing fine light wise, as they're all forming new roots, leaves, etc, albeit slowly. However, this is really only 3-weeks so far, so take those results with a grain of salt (size left you your choosing)
