How long have you had your orchids?
The producers who market orchids with those instructions are motivated to sell more orchids, not to help you grow a beautiful orchid for years to come. They want you to buy an orchid in bloom, water it with ice cubes until it finishes blooming then throw it away and buy another.
People who really grow orchids are unanimous in their agreement that watering with ice cubes is harmful to the plants in the long term. Please feel free to wander over to the Orchids forum and post a question about this. You will not find a single person there who would go near one of their treasured orchids with an ice cube.
