Ivy, may I ask where do you live? If you can grow tillandsias, you can grow staghorn ferns and orchids. Staghorns actually require less light than tillandsias, so indirect light is fine. They don't like direct sunlight and if they get sunlight between 10:00 AM and 4:00 PM, their fronds will "sunburn". Same for orchids. If you can mist your tropical plants weekly during their growing season (March-September), amd bi-weekly during the fall and winter months, regardless of what species they are, they will do well.
