Sharon, there is an orchid mix that is sold in the home improvement stores and it says Phalaenopsis orchid mix. That's what you want to use. It already has everything you need in it. Put your orchid in a clay pot with a hole in the bottom for drainage, along with the orchid mix, then place the pot on top of a tray with pebbles. Place water in the tray, but do not let the pot touch the water. This will increase the humidity around the plant. You can also place some bowls of water in the area if it's very dry in your room. Hope this helps.
