For those of you who were wondering why my spider room isn't covered in greenery and plants, and cool lighting, I have the answer. Some people really go to town on turning their spider rooms into fake jungles, but working on the theory that the spiders can't see well enough to tell what you have done , and therefore couldn't care less, I'd rather make their tanks more naturalistic, and keep the room hyper minimal, so that... you guessed it, there are very few places for escapee spiders to hide - not that this is regular occurrence !

I also have a VERY bright light in there, only turned on briefly for photos, when emergency help is required, or when trying to persuade any escaping spiders that they want to go find the dark tubes I have left out for them. Most of the time, the room is at slightly less brightness than whatever is going on outside, so they still have a good sense of what is day, and night, yet are never exposed to harsh direct sun. At night, there is a permanently on, but very very dim pure red LED light, which I use to go in and check on them periodically. Only the Poecilotheria and the Psalmopoeus seems to run from this - the others appear not to notice it at all.
