Advertisement A recent thread came up, I can no longer reply to it but it brought up a good point and my "Devil's Advocate" self is here to ironically and rarely voice for the new comer... Although the forum pitchforks were brought forth in the other thread cuz of a newbie suspected of classic ignorance and an inevitable disposition caused by being out numbered. The the question still remains. Is "cross ventilation" really needed? I think this question is widely misunderstood when it relates to Avicularia keeping. Avicularia certainly thrive better in drier conditions, I have no opposition to that... but that's the key, no matter how that is accomplished... I have raised them every which way to test the tolerance over the years. In my experience, the notion of cross ventilation is merely a newbie guideline to avoid an over moist / stuffy enclosure brought on by the misguidance from out-dated internet information telling of high humidity needs. In truth, if kept on the drier side with adequate hydration there should be no problem raising an Avicularia IME. The problem with common husbandry guidelines like this is they are not absolute and are geared toward the weakest link (example, the need for water bowls). Unfortunately, as it goes, the first generation(sophomores) taught these guidelines, warp it into fact and then the pitchforks come out when talking to the next generation(freshman) of newbies. Over time, I have seen these guidelines regurgitated into a flat out fact/myth. As long as the adequate ventilation is applied to assure a drier enclosure and the Avic is well hydrated, it does not matter where the holes are placed. There is not one of us that hasn't had a spider die under the guidance of "perfect conditions". So it's hard to say what the cause of death was, especially, knowing other have survived in worse conditions.
