Thats not a very big variance. Try an UTH with a thermostat for the warm side to get higher than 80 F. As for the substrate I have had bad luck keeping aspen moist because it tends to mold, I would put a towel over the screen to keep in the moisture: Substrate and Furnishings

In the wild, these pythons tend to inhabit savanna and grassland habitat, residing primarily underground in rodent burrows. Underground, the relative humidity is much greater than above ground, so while the savanna is not known for being particularly moist, these pythons do thrive best with a secure hide that is also packed with damp moss. The damp moss and tight quarters help these shy snakes to feel safe and secure.
Reptile bark (orchid bark), cypress mulch, pulverized coconut husk (bed-a-beast), or a mixture of both are prime choices.
Avoid any excessively drying bedding including pine shavings, sand, or paper products. And never use a cedar bedding...cedar is toxic to all snakes!
When designing a terrarium for this species, keep in mind its secretive nature. Provide ample places to hide on both the warm and cool regions of the enclosure. Half-logs, cork flats, cork rounds, and grapewood all make excellent hides for ball pythons. Additional climbing structures (sticks, rocks, plants, etc.) may be used, but avoid over-crowding the tank.
Water and Humidity

Water should always be made available to ball pythons in a sturdy dish large enough to allow for occasional soaking. Water should be checked daily, and replaced immediately if fouled.
Ball pythons require localized areas of high humidity within their cages. Once or twice daily misting of the entire enclosure with room temperature water in a hand spray bottle should be adequate in most situations. Do not allow the substrate to become saturated. A good misting schedule should result in the bedding drying out almost completely between mistings. Use of a cage fogger is another simple way to increase humidity in the cage without completely soaking the bedding. The rolling mist the fogger typically creates also makes for a natural, tropical effect within the cage!
