Place your orchids in a cool room or shaded area. Orchid care is essentially simulating a rainforest environment, so avoid exposing them to direct sunlight and instead provide them with soft and diffused light.
Water your orchids once a week with clean tap water until the pot mix feels damp and soft. Overwatering your orchids may cause their roots to rot. Generally, it's better to under-water rather than over-water your orchids.
