Dryadella edwallii culture advice

I have had this plant for a couple of years. It was in bloom when I bought it. I haven't been able to get it to bloom again. It looks really healthy, keeps putting on new growth. I'm growing it in my house in a little tank under lights. I think the light's OK. There's a red tint to some of the leaves.
I have the Baker's sheet which shows 53-77 f with extremes of 32-100 f.
Any advice?
I'm tempted to move it into the greenhouse where the humidity is MUCH better but it gets up into the mid 80's pretty much daily.
How are any of you growing this species?
TIA

 

Thanks Forrest! How much light do you have it in? I don't need fc just some rough idea...

 

Thanks again! I have just the spot! And thank you Jon for the coroboration...
