No moisture. They were in a room of our home (a mobile home), that I call the plant room. For the first two years, air from our evaporative/swamp cooler, was blown into our home, through a screen, then into this plant rooms window, but after that, for health reasons, I discontinued using the evaporative/swamp cooler, and switched to traditional air conditioning (which cools by refrigeration and removes moisture from the air, when the former added moisture to the air. In these conditions, they were kept cooler, below 90F, but the percent relative humidity was then, always in the single digits. No captured insects, since in the neglected period many spiders kept them tented with webs, taking advantage of their insect-attracting presence, I'm sure. The spider webs did help keep dust off of the plants. Nearby surfaces and older webs became heavily loaded with dust.
Actually, earlier (by several years), my entire collection, was exposed to an initial period of neglect, of several years. Then things seemed to be leveling out, and I sorted through my entire collection, to identify what had survived, and what had already expired. I took photos of all the survivors, after consolidating them. Originally my collection extended to ~ 90 shoebox sized plastic trays and several other very large plastic trays. Somewhere I have photos of all those initial survivors. Initially I posted them in an older thread, where I already explained this. Once I relocate those pics, so I can restore them to functionality in that thread, I will refresh that thread, then.
Back then, I also began trying to rehabilitate those initial survivors, but after consolidating them, cleaning them up, photographing, and watering them, once - I again had to continue neglecting them. And, just this past September, of 2014, I have been able to begin truly rehabilitating the survivors, of the survivors. These survivors of the second bout of neglect were only air conditioned in this period. A much larger percentage, did not pull through, than the first time.
More, soon . . .
BTW, nice Paphiopedilum armeniacum. I once grew that species and Paphiopedilum delanatii. Though I also had many others, those two were among my favorites.
