Your light is great I'm sure because the other two hybrids bloom and they both need high light.
The only thing is the winter.
How cool does it get in the winter in Hawaii?
I am with you that that is the only thing I would suspect.
Neos are from southern parts of Japan, South Korea and into China, and these places get snow although it is freezing cold the entire winter, it does get very cold.
By the way, I am in love with your White Crane!!!

The flower shape is so well-balanced.
I see it's got some growths at the base.
I would love to get a piece of that plant in the future.
Think of me!
