Winter rest for Dendrobium keikies?

[drtd]

Earlier this spring I acquired a couple of Dendrobium NoID (nobile type) keikies from my mother, and have been growing them on through the summer. They have each put out two new canes and many new roots, but are still very small. The largest cane is maybe 2" tall. Should I observe the winter rest for these plants, even though I don't really expect them to bloom being so young?
