vanda watering question

[april]

I know you are all probably sick of this question, but I really could not find an answer in the archives. Here goes: Can vandas with free roots (no pots) get too much water? I hear from the threads that you can never over water them. I am a bit obsessive so whenever their roots are getting really light I water again. I am in Florida, it is in the 80's and the wind is non -stop ( I live on the bay and put a piece of plexi-glass to help shield them but they still get a lot of air circulation and their roots dry out really quickly) They get plenty of sun and I make sure that I never water after about 4PM.
