Tracey, you might like to try the Disa and the Masdevallia orchids in your grow chamber. The Masdevallias are my favorite orchids, and have had some success with them in the past, but they are cool growers (High Andes) and they just don't do well in the dry San Jose weather most of the year. I also can grow the tropical pitcher plant Nepenthes, but they really need high humidity to be at their best, so they required daily misting that wore me out. And, most of the carnivores don't really like tap water. Rain or distilled water works best, but this is not carved in stone. Check out this California Carnivores website
http://www.californiacarnivores.com . I've visted this place a few times, and always find something new I want to take home. Daiv, as for my Oncidium papilio, I grow it indoors in an all day sunny room, I mist the plant weekly with a quarter strenght epiphytes delight plant food from Tropiflora in Florida, and keep the bark on the dry side. They get a thorough watering one a month and keep a shallow level of water in the saucer. They sell the above mentioned plant food at Home Depot with the Bromeliads.
