Windowsill setup for Oncidium and Mini Dends

[DManley]

I am getting a few "Real" orchids to join my 3 NOID Phals on a South facing windowsill table. They will have South and West exposure. I live in Michigan, and we have trees in the yard, so the light will be a bit subdued in the summer, but decent in the Winter when the leaves are down. The Phals have done fairly well in spite of the temps dropping a bit in the Winter, and some low humidity. I plan to put Orchids outside for the Summer starting next year.

I am getting Dend. Bardo Rose, and Dend. Berry. I am also getting Oncidium Gower Ramsey and Oda. Marwill. I am hoping that these will all work with Windowsill light and be okay with the humidity. (I will keep a teapot on the woodstove this winter.) Any advice on these orchids? Any advice on my growing setup? Will any of them need some artificial light in addition to the sunlight? (For winter rest, I can move the Dendrobiums upstairs to a cool bedroom with South windows too)

Lastly, are there any other groups of plants that would work well for windowsill growing? I am hoping that the Oncidium takes off. If it does, I will try a couple others like Sharry Baby, or another fragrant one. I am also thinking of Mini Catts, but I would need to add some artificial light to make them happy.

Thanks,
Dave
