i didn't know about pogostemon, nice, so great, i can't be certain about the PAR, i dont have one, but there is lot of light with 2 t5honice, I can see most of the plants growing well...
the limnophila hippuroides leaves are purple on the bottom, green at the top, so the top-down photo doesn't show the beautiful purple leaves 🙂
With 300 par, the top parts of the P. Erectus should be turning a golden yellow soon:
