As some of you may know, I recently built a grow shelf. Here's a pic to give you an idea:
So the problem I'm having is keeping the humidity up. The highest it's been to is 50%, and usually it's at 45%. I have a humidifier on 24/7, and a reservoir, A.K.A. a bowl full of water. My only plant has a baggy over it so it should be okay. Anything I can do? Do I need a better humidifier?
