What type of medium are you using? It looks like sphag moss.

Im using a mostly coconut husk mix. Probably 70% husk, 20 % NZ moss, 10% perlite/charcoal
After them being rotten in compressed soaked spagnum moss I decided since I was a beginner the moss would be used quite sparingly.

No issues, water when just about dry all the way through. The plant will send roots to the middle/bottom if it wants more moisture.

I also strongly suggest not to mist the phals, 40-50% humidity is enough and I think the misting has a chance of causing more issues than the dryness on top.

One more thing, the lights seem awfully close to the tops of the phals to me. With the spiral CFL's, I'd say 6"-12" from the tops.

Good luck,

Bob

Actually I do have them repositioned now. Its one CFL42W per glass bowl right now and 6-8" above. I had them closer in order to get the right intensity but the narrow field that it emits didnt cover enough, so i get less intensity now but more coverage.

Thanks for the info. I wont mist, and ill just water once a week. It has good drainage anyhow, and sending roots to bottom for more moisture makes sense. Just the tops drying out looked a little worrying for a noob orchid grower
