Hi Barbara,
Sounds like you have a lot of light and a lot of orchids! I have about half as much of both of those. Just ordered some LED fixtures and am looking forward to setting up a grow space in a 9x12 sauna that we never ever use. I will now have enough light and am already making lists of the new orchids I want to add. Yes, let me know if you are going to go to Marlow's at the next open house.
