Had some conflicting advice....

[nazanova]

Ok so I know this forum isn't about Tarantulas but this is one of the forums I trust the most when it comes to advice and to be frank I'm quite lost right now. So I'm planning to get an Avicularia Avicularia next week and up until now from the research I've done they should be kept at around 75-85% humidity. But I have recently joined a Tarantula forum where a member had told me he keeps over 90 Avics at 40-50% humidity and the only thing he has towards that is a water bowl! No misting whatsoever! Now I'm calling bullshit but if he's claiming to have over 90 Avics who are alive and kicking at those humidity levels surely he's right? But he's the first person I've EVER heard keep their Avics like this so I don't know who to believe. Every caresheet I've read and reputable youtube video I've ever watched has said 75-85% humidity so is he just talking ****? If anyone can help me it'll be deeply appreciated!
