Thanks all! The CCs are doing really well for me this year.
I have a shelf set up in my bedroom with a light over it that gives them a full 12 hours of light each day. The temp never goes above 68ΒΒ°. The posts are set in a double flat tray, with a pierced one nested in one without holes. Each week, or so, I flood the trays with water. The plants take up what they need and the rest provides humidity. (The orchids are loving the extra humidity, with 4 out of 7 spiking!)
I'm especially proud of the yellow ones (3rd from left). I picked them up last year when they were about done blooming, so I wasn't quite sure what to expect. All I knew is that they were a yellow of some form.
