You know in orchids once you get the humidity where you want it the next level is to have good air movement.  I used to grow under lights in a basement and one thing that helped the orchids was to keep an oscillating fan going.  This really improved the plants.  Since then I've moved to a greenhouse however still had lots of fans.  In the 96' x 25 I had oscillating fans every 10' which ran all day.  Just a thought.

 

"Sticky with a breeze"

This is a timely thread for me.  The plants that I've been growing indoors all winter have been looking a little sad lately.  They grow a little taller every day, some almost up to the lights.  After researching the forum I bought this fan from Amazon.

    

They perked right up.  Everyone is happy again   :)
