I have my light on a timer and it stays on from 7 A.M. to 7 P.M. It only provides low-to-medium light, but keeping it on longer compensates for that. I also use Flourish Comprehensive with each water change, and I'm sure the roots of my Anubias benefit from the non-copper root tabs I insert into the gravel for my other (non-rhizome) plants which are nearby.
I'm sure with some ferts and stronger or longer lighting, yours might bloom, as well.
I love my Dojos; my Dojos love me,
As long as I feed them, happy they'll be!
