Welcome to the forum. You have an orchid called an Odontioda.
Light: Go for filtered light ranging from 1000 to 1500 foot-candles. You want the leaves of your orchid to be bright green - not dark green. If they turn red or pinkish, that means you are giving them too much light. Dark green is not enough light.
Water: Let them *almost* dry out between watering. The media can be kept moist, but should not be *wet* or soggy. Do not let your plant sit in a pan of water. This orchid should drain completely.
Food: Fertilize your plants once a week with a 1/4 strength fertilizer. (weekly - weakly). Be sure to flush out the pot on the next 'watering' day with lots water.
Air Movement: Your orchid will appreciate air movement and this will also help to keep bugs and other pest off of your orchid. Put them where they will get enough of a breeze to move the leaves around just a bit.
Humidity: Oda. need relative high humidity 50 - 75% is about average. If you can, create a humidity tray with some marbles or rocks. A shallow pan that you fill with marbles or pebbles and then water. Sit your orchid pot on the marbles keeping it above the water level and this should help keep your humidity up.
Media: We pot all of our orchids in bark. It is what works for us. I recommend a medium sized bark mix. Get it at a local box store or home improvement store. It will be labeled for Orchids.
