I installed some drywall backwards, is there a way I can hide the imperfections?

I bought some mold resistant drywall and installed it with the green facing the the inside of the wall, because that's where the mold problem was Little did I know the other side of the sheetrock isn't quite as smoothe. In the sunlight you can see horizontal ripples all the way down. Is there a way i can hide this, or do i have to rip it out and redo it.
