My Methods for Keeping
This section is just to let people know that although I give care sheets with specifics in temperature and humidity, I have added these for those that use gauges. I do not use a humidity gauge, but I do have thermometers.

I try to keep my room at a temperature of 70 to 85 degrees, going down at night. I do have some trouble with it as I rely on the boiler system and radiaters to keep my house warm. I still need to find a good way to keep the room at a more constant temperature.
One idea that may help is if you can comfortably wear a T shirt when working in the area, then it should be warm enough.
The above tanks are made of plastic with a secure clip-on lid, they are called a lot of things depending on manufacturer, such as "Kritter Keeper" and "Pet Pal".
In general they are a good tank for your spider, but I have found here in England that they are very drying and keeping the humidity up is really hard, so I only use them for species such as Brachypelma smithi, and then with trepidation.
One other problem is that photographs are not as clear through the plastic as it scratches quite easily.
The glass ones above are custom made by a local company (Custom Aquaria). I tend to order non-standard sizes but they have a large range for any keeper and are seen at the BTS show every year.

These are sometimes called T-Pot tanks as they have glass lids as well as all glass tanks.
You can get a mesh section in the back for aeration and I would tentatively suggest that a small section would be a good idea as the all glass can sometimes get too moist.
For high humidity species these are great but again I would think about a small mesh section. It would only need to be about half to one inch diameter to do the trick.
Such things as sweet jars can be utilised to make really good arboreal tanks. The one above is home to my Psalmopeous irminia. I drilled holes in them for aeration.

The equipment above are essential I think for the budding keeper. The tweezers are about 6 inches and are invaluable for removing exuvium and prey item remains, with little disturbance to the spider.
The ruler is nice to help assess the growth rate of your pets, but is shady at best as there is no easy way to measure them.
The water bottle is not generally used to spray the tanks but to help direct the water where I want it. With out the lid it is also a good way to pour water in the water bowls.
The tank to the left is a tall one for arboreal, specially made it has a vented section at the top rear section. My Peocilotheria regalis lives happily in this tank, but will need to be moved to a bigger one eventually as it is about 12 inches tall and 7 by 7 wide and deep.
