Ultimately, what is more important; humidity or airflow??

[ColoradoBirddog]

The orchids I'm growing in it are Catts, LCs, Phals and a Neofinetia.

So, if you can picture, I have a small "room" fan inside, at the bottom of the tank, running 24/7. Coming in from the top is my fogger, and then a glass panel that is set open, the entire width of the tank, for about 4". Finally, I've got a brushless computer fan bringing in the fresh air, again for 24/7.

In that manner, the airflow is very good, but like I said, getting a little drier than what I think would be good.

Since starting this thread, I'm experimenting with just using the top fan, 24/7. But, any input is appreciated.
