Thanks I was hoping it was safe to do it now. I don't use moss as I've never had good results with it. It's reaaallllllly dry (10 % humidity) in my apartment this time of year. What about shredded coconut fibre? I've used it with other plants but not with my orchids. I usually use the chunks for the orchids but I see where that might not hold enough moisture for the small plants. If it's mixed with some larger particles of something to increase the drainage a bit would that work?
