I've had a little Sterochilus dalatensis for two or three years now and all it is doing is 'existing' -- not flowering not even growing. Originally, it was a mounted plant but was declining rapidly ... [Mounted plants rarely do well for me -- they just dry out too darn fast.] Presently, I have it in my terrarium in a 1" pot with coconut husk chunks, large grade charcoal and a topping of sphag. There is a fan in the tank for air circulation. The plant is hung near the top of the tank. Lighting is provided by 2 coiled fluorescent bulbs. This lighting has been sufficient to bloom Den oligophyllum as well as E. polybulbon.
