The soil will cope, as will the plants, but you must use a very porous soil, that remains friable, when moist. Since I am not using misting, but dripping as a primary means of hydration, the soil will only be getting satuarated heavily in localized areas. Once the soil has all it can handle, there is 6" of space to drain and collect, with the soil hopefully remaining above and out of contact with any standing water, which will be pumped out on a try to be determined schedule.
Regarding their preference for long and narrow or square, I was limited by the pool table in the center of the room. My animals are very shy and rarely venture to the front, so most of their traveling is done laterally, along the lengthy. Now, it's also worth noting that I kept most of the taller, denser plantings to the back of the enclosure and most of the branches/vines run side to side, none going from back to front, so they'd have to expose themselves a bit more to come towards the front of the enclosure and rarely are they willing to cross an open stretch of vine.
My animals do not associate me with food. They associate me with sinister intent and although they are less opt to run away from me merely staring at them, they are sure to stay as far away from the front of the enclosure as possible. They make my life and feeding them as difficult as possible, refusing any bowl feeding, having tried every conceivable feeder bowl, even leaving them in place to get used to. They are not very much fun, at the moment , but they are loved and doted on, anyway.
