Contrary to the above forumers I would support the Ice cube watering as long as you do it quite often and not with a couple of ice cubes! I have 16 phals and spend most of last year watering them with filtered ice from my fridge since the tap water is too hard. They are doing great. As long as the cubes are not touching the roots i found this to be tolerated with no stress from my phals. For the results of this methods you can check my phals post! All they need is light and water... If you decide to use cubes then you must water them more frequently. As for the ice, it melts and drips and the temp of the dripping water is considered cool, not cold. After all rain is not at room temperature! Good luck with your phals!!!
