Most varieties prefer bright light and warmth as well as a reasonable degree of humidity.
For most household conditions, pots are best because they hold more moisture around the roots. Teak baskets are really best suited for high humidity areas such as greenhouses, or growing chambers or outdoors where they could be wetted or misted every day. Plants in pots should be watered just as they medium dries out, approximately every 5-7 days for larger clay pots. Most vandas are treetops on ridges along rivers and prefer bright light. In terms of indoor culture, they require a south window.
