These are plants, so green will not do much (just like corals), but red will (unlike corals). The ideal spectrum for them is the purple grow lights. I don't know anything about programming reef LEDs (never used anything but black box lights), but a reef LED is overkill for plants.
I grow mine under some generic cool white flood light bulbs that provide around 1000 PAR right at the bulb. Bulbs are 12" over the top of the mangroves.
I grew them just next to a window for a couple years, then added the lights. I noticed that their growth improved a bit with the addition of the lights, but it absolutely exploded after I started heavily supplementing iron.
Note that by "growth absolutely exploded" I mean like 2 leaves a month instead of 1 leaf every 2 months, these are not exactly what I would consider weeds.
I'm experimenting with 10-10-10 fertilizer to see if I can increase growth. The mangrove_manual.pdf that someone else linked in an earlier post is definitely excellent, and I'm going to start dosing manganese to see if that helps.
I am growing mine in freshwater, in a container without much else besides some frogbit growing around their roots.
