I read your post below you have few issues you have to resolve.
First, your inquiry for a bp care sheet, check out proexotics snake pro-pack at proexotics.com and or care sheets from NERD.
You should have gotten the care sheet prior to purchasing the ball, but that is neither here nor there.
Second, that fogger works actually in combination not just with heat but electrical current that atomizes the water to its vapor form. Small current but if your snake ever sits or touches that copper panel in the fogger it can shock and or burn him severely. Trust me I have seen it on many animals, monitors and snakes alike with people that used it for humidity. The animal may not do it today maybe not tomorrow but it will end up touching that thing and you don't want to see the results.
Lastly, below I read you have "fake grass" in the tank, as in astro turf? That is your major problem. Proper ball husbandry says to keep your balls on either cypress mulch, aspen bedding, and or paper towels. The "fake grass" is where you humidity problem lies, its plastic like which means any mist your vaporizer gets on it quickly evaporates into the air and out the tank because it's not porous, it doesn't hold moisture long enough and efficiently enough.
So here is the simple solution and you will be very happy with the results. One, dump the fogger leave his water bowl alone and clean no things in it. Two, dump the "fake grass/astroturf" what ever it is and use aspen or cypress mulch. Three, get a second hide and use damp sphagnum moss under it as a humidity chamber spray it every other day so the water beads on the sides of the hide and that will make the proper humidity and keep it centralized so the animal can choose what and how it needs. Trust me during times of shedding you will see the snake in the hide more often then not. Leave the second hide dry and normal on the bedding. Once a day with a good misting bottle spray the bedding if you still feel your humidity is low. But remember two much all over humidity leads to respitory infections, stress, and blister disease. A stable high humidity chamber is fine and all you need. Even if that hide hits the hi 80% humidity it's centralized and then snake can come and go there as it pleases for however long it needs.
Best of luck.
Read those care guides.
