swords...When I got the mold the heli was out in the open. The utrics were in the corner, so they probably got little air flow, and the hamata terrarium was uncovered, but it was quite tiny and the bottom part did not get any air flow. There is a fan on now, and I think I'm just going to ditch the terrarium. Hopfully that should cure the air flow issues.
amphirion...I have not. I think the mold came from something I brought in from outside, as I described in the last thread.
I have to say I disagree with a big part of that--it is anything but dim in my room. I actually had to move the lights up and away from my plants after winter started, because my neps were starting to burn a little. Even now many of the plants are getting dark red leaves, and all of the plants pitcher continuously. The sundews are also growing quickly and becoming quite dewy, and the heli is putting out several new pitchers (apparently despite the mold and recent transplant). They are very healthy (check my last picture thread if you don't believe me)--and because they are so healthy, it seems to me that the light must be more than sufficient.
Also, the only reason some of the plants are in bags is to acclimate them or to allow gemmae/seeds to germinate. Many have already gotten past that stage and are out in the open, and others have bags that are riddled with holes and are almost ready to come out. It's not a permanent thing by any means.
However, I think you may be on to something with your formula. Most of the things the mold attacked were in places which got little air flow (like the bottom of my tiny hamata terrarium).
cool+damp+low air flow=mold? Maybe.
