Yep. All anubias and java ferns are rhizomes and should be treated accordingly. I simply wedged the rhizome into some crevices of my driftwood. After a couple weeks, the roots took hold. I grow a leaf once or twice a month or so.
And was this all in a low tech tank?
55 Gallon Planted
3 GBR, 2 Bolivian Rams, 1 Juvenile Super Red BN Plecos, 9 Oto Catfish, 9 Bloodfin Tetras
Rotala Indica, Cardamine, Crypt Spiralis, Pygmy Chain Swords, Dwarf Sag, Lutea Crypt, Wendtti Bronze and Red, and Floating Frogbit
I have a standard 55 gallon. I have various anubias, swords, water sprite, wisteria, lutea, micro swords, pellia, and jave moss. My lighting right now is a dual 48" shop light with 2 GE 6,500k T8 bulbs and nothing else. There are also no reflectors on the shop light.
These plants will probably be okay with the light you have. Instead of spending money another light, you could do a DIY reflector. Might check out hydroponics shop for 1.
