8x2 aquarium that I modified. It is completely closed off and I cannot see inside of it. I insulated all of the glass because it sits in my garage. It has 2 CHE's on both ends on thermostats. One end has a mercury vapor bulb and the other just a plain 65 watt flood light. Temps alway stay around 82 and humidity always around 85. It has a pvc pipe that runs the length of the enclosure with holes in it that is hooked to a humidifier that I turn on about every 3 days. Here is the thread for the enclosure, like I said thought, it's completely insulated now. I couldn't find my thread but I did find where I had showed someone else.Such a cool growth pattern. What is your setup?
