Why on earth do people water their phals with ice cubes?

[VONDI]

I guess when I said for 'a few minutes' I was exaggerating a bit. it's more like a couple minutes on a low stream. I rotate the pot and watch through the translucent plastic to see when the medium seems saturated. The pots I have are probably about two or two and a half cups in volume. One has drainage holes in the bottom. The other has tiny perforations all over the sides.
As I said, my two orchids seem happy.

I'm just wondering what other methods growers use.
