Below are pictures of my two terrariums. Each tank has two 20 watt florescent lights on an automatic timer I keep synchronized to the outdoor photoperiod. Inside tank temperatures are usually constant at 70 degrees F. Humidity is always greater than 50%. Other than the florescent light hoods, I have no top on either tank for moisture retention. I've never found it necessary. An overly humid tank with poor air circulation promotes fungus growth which can kill carnivorous plants. These tanks are home to the following: D. Adelae, D. Slackii, D. Aliciae, one Pinguicula x Titan and all Nepenthes. I mist inside the tanks once or twice per day to water the Nepenthes (avoiding the other plants). Misting in this way has the added benefit of circulating the air. The smaller terrarium's plants are watered via capillary action. I leave about 1cm of water in the base of the the tank at all times. This seems to work fine.

The reflective material wrapped around each tank greatly increases the amount of light shining on the plants. The material I used is sold at home improvement stores as an insulator for water heaters. I made the front panel lift up for viewing the plants.

At the time the pictures below were taken, I didn't have any reflective material for this tank yet; However, it now looks identical to the one above. The plants inside have since been repotted. Presently, this tank holds my three largest Nepenthes, two of which grow at the rate of 1cm in stem height every two weeks.
