Vanillas are terrestrial and they grow well in a mixture designed for African Violets. Keep the medium moist, but not soggy and mist the vine with water a couple of times a day. Once a cutting is established it will grow rapidly and it will produce aerial roots along the stem. You'll need a trellis to wrap the growth on. I don't know about your lighting. Mine is grown outdoors in bright dappled sunlight. Keep in mind that our climates are vastly different.
