down side of semi hydroponic?

[ladyslipper]

Hi guys, I am really comfortable with moss and have never had anything nasty happen with fungus or rot. I am becoming intrigued by s/h culture for my phals (& few paphs)

My question? Whats the down side? is it expensive to switch over to s/h? what changes do you have to make to your growing area?

thanks for your opinions ;-)
