Gracillaria lighting ?

[NanoReefLife]

Any suggestions for lighting Red Gracillaria in refugium for best growth and nutrient uptake ?

I can't say for sure except that I think Gracilaria is pretty adaptable. Finding empirical evidence is hard: There are tons of G. species and some are more shade-adapted than others.
In general, I think they tolerate fairly wide ranges and I haven't found difficult in keeping them.

Anything. It will grow under a screw in CFL bulb just fine.
