Thanks everyone for the warm welcome and advise, especially Charlie.
I did take them out of the clay pots. Unfortunately, they weren't inside clear plastic pots. They were in opaque brown plastic, so I can't see the roots. I saw that someone mentioned using a wooden skewer to check if they are wet...I'll try that. I'll probably attempt to re-pot them when they are done blooming. They have drainage wholes on the very bottom of the pots, but it's a bit tempting to try to cut some slits on the side to give them more air and help them dry out more...but I am too fearful of damaging a root in the process.
I also made some humidity trays to put them on, since it's a bit dry here during the winter.
I was wondering though, how long would it take to notice a difference in the leaves if they are getting too much or too little light. I have one by a window with a sheer curtain (but it's been rather overcast lately), and the other under a grow light that I am hoping isn't too strong (it shares the light with a very happy African violet).
PS. Just wanted to mention that this forum is what helped give me the confidence to attempt this endeavor. So I'm glad to be here and to be an orchid owner.
It's something I've always wanted to do. CHEERS!
