Yes, it's a 60" by 60" by 30" chamber. The actual growing space I use is 60 by 45 by 30. It's infront of a window, with 4 daylight tubes ontop, closest to the window, and on the oposite side, on oposite corners are the 125 watt cf's, two total. The truncata I got in a trade was growing on the green side, and after a little time in this setup, it has started getting much more color, ie red on the leaves and pitchers. The only bad thing about it is the occasion boon in the insect population in my room, and the fact that I can only maintain a minimum 70F lowland conditions. This is with my air conditioner running. It should get cooler during the winter though, if I open those windows. Any other good methods of cooling a chamber like this?
