I have heard people talk of the ice cube method, but I prefer to water my orchids the old fashioned way. This is especially true when I fertilize them. I don't know how you'd fertilize them if you used ice cubes? Anyway, I put mine in a mixture of orchid bark and sphagnum moss. You can use either the fancy blonde "orchid" sphag., or you can just use run of the mill sphag. I think the moss helps because they don't seem to dry out as quickly, and I have had far more leaf growth since switching to this mixture. I water mine about once every 4 or 5 days depending on when they feel dry to the touch, and I fertilize them every 3rd or 4th time I water. Some have to be watered more frequently, and some less... I just touch the top of the potting medium and if it feels dry I run them under some water until the water runs out of the bottom, making sure that I get the whole thing wet. You can cut off the flower spike, but if it is still green you might want to leave it for a while to see if it re-flowers out of the same spike. Sometimes they will grow more flowers out of the same one, and will sometimes re-flower more quickly because they won't have to grow a new spike. Just make sure there are holes in the bottom of the pot so they don't sit in water.
I hope this helps. Indirect light is good, but my Phalaenopsis orchids and some of my dendrobium orchids require bright indirect light.
Good luck, and just remember to be patient.
