I've been interested in carnivorous plants since I was a kid, but I haven't had any for about a decade. Recently, though, the idea of growing a venus fly trap in my dorm room hit me. There were a few issues I had to overcome before growing one, though. There are three major environmental factors venus fly traps require: high humidity, lots of light, and a nutrient-poor soil watered with distilled water. The soil is an easy problem to solve. Humidity is a bit trickier, but even in a place a mile above sea level as long as the terrarium has relatively small openings for air the humidity stays high enough inside. Light is another big issue. I don't a whole lot of sunlight through my window, so I integrated an LED light source into the terrarium. I have it running on a timer 10 hours a day, so between this and the sunlight I think it's getting the rough equivalent of a day of direct sunlight.
