I have only ever seen one Vanilla Vine. It was in a glass-house set for Phalaenopsis.

Here is snippet cut from an AOC article about Vanilla.

"Vanilla - Cultural Needs

If you still want to try your hand at growing and, ultimately making your own Vanilla, here is the cultural requirements. (Not recommended for indoor culture due to size of the mature plant)

Vanilla prefers a partially shaded location. Remember it grows naturally under the forest canopy, clinging to tree trunks. The temperature should be warm (around 30°C) and night temperatures not lower than around 15°C. Admittedly this is the optimum. As previously stated it grows here but the minimum and maximum temperatures exceed these figures.

Vanilla prefers a moist climate. The humusy soil or potting medium should be kept evenly moist at all times. Humidity should be kept high, and, as with any orchid, good air circulation is essential."

I have a lot of Vanilla but growing in the garden. What I have found with them is that if a cutting is planted into soil it will rot off. They do better if cuttings are laid on top of the soil and kept in humid conditions. If they're going to be potted then the medium should be the same as for an epiphytic orchid (which is what they are). They also need climbing room and plenty of light, but not direct sun. Once established humidity isn't such a big issue but they will do better with more.
