Thank you. I will keep the Serenade in mind as I think a few different local shops have it.

Unfortunately my plants are very cramped! I already keep my circulation fan on 24/7 but I will probably keep the oscillating direct fan on 24/7 too. I think I'm going to get a second circulation fan.

It's kind of odd though as humidity readings throughout my house are 45-50% and it's supposed to be 29% outside. Maybe I need to upgrade my meter as it's like 5 years old...
