I have a Catt question. I know that they like intermediate temps, humidity and to become almost dry between waterings. This time of year I water about once a week with half strength 10/10/10 every other watering, and I mist them in the morning (lightly) a few days a week. There is a humidifier in the room and they have humidity trays. The stalks look healthy and there were several new shoots, but no buds. So, if water, temp and humidity are about right, and the plant looks healthy, my issue is probably light, right? where should I put it? If anything the leaves are a bit dark, (it is in a West facing window), but it has not been particularly sunny this winter. Any suggestions?

I keep catts in mostly southern light in winter. The tricky part is spring, when it is so easy to burn leaves after a relatively dark winter. Do you have a south facing window where you can put them in winter?

I grow my Cattleyas year around in bright light inside and outside in Summer they get only minimal protection! The darker leaves are an indication that they probably need more sun.
But, as Kathy said, if they are not used to it, one would have to acclimatize them carefully or one might look at burned leaves.

Thank you! I do have a South Facing window. I will gradually move it to that window for the rest of the winter and see how the leaves look as spring progresses.
