I found this plexiglass aquarium and the table legs in a dumpster down the street. I hung two shoplights from the top, the back wall and sides are covered with mirror tiles, and small white marble chips cover the bottom. This substanially boosts light to the plants, gives the impression great depth to the case, and focuses light onto the larger Phalaenopsis plants outside of the tank on the table. Light tubes consist of alternating cool white and warm white bulbs. The marble chips sit in water, but surprisingly, humidity is rarely higher than ambient, supporting my view that pebble trays are an insignificant source of humidity.
