Most of my collection is on spag/cork in an orchidarium, and I'm not really pleased with how some things are growing/faring. I've gotten some suggestions that treefern might be more suited to my conditions. Basically, I feel like the spag keeps things too wet all the time, but the bare cork would be too dry. With treefern, I'm wondering if the surface would dry off quick, while the inside retained moisture, and the roots could find their own happy medium. I grow mostly warm/intermediate bulbos, high airflow, watered daily in the morning. I have also seen the rampant success a lot of bulbo growers have with TF. Your thoughts would be greatly appreciated.
