Do not water your orchids with ice cubes. That is nothing more then a sales gimmick!
For the most part, the orchids we grow are tropical plants. Tropical as in warm climates. As far as I know, it never rains ice cubes in tropical climates.
Fertilizer to be used can be just about anything for indoor plants. I use an 20-20-20 blend at 1/2 tsp. per gallon.
