D. kingianum evaluation, and advice?

[ColoradoBirddog]

well, in the past, I never had luck with dendrobiums. But, I wanted to give it another try. Now I have 4!

Ok, so I was told to "bake" dendrobiums to get them to thrive. I've got them outside of the terrarium, and next to a western window. So, it get some light throughout the day from my grow light, but it also gets about 5 hours of direct sunlight. Am I giving it too much light?

This particular one came as a couple of keikis. As you can see, it's got a pretty mature keiki as well. In the 2nd photo, you can see 3 growths on the right. They're a little loose in there. So, I'm wondering. Can/should I separate that mature keiki, and repot it? I'd like to keep them together.
