Brand new bp owner

[FNG]

Hey guys,

I've been reading a whole bunch on this site in prep for getting my first ever snake and, as of 2 days ago, i am the proud new owner of a beautiful pastave female. i don't know her weight or age (i forgot to ask) but she's just a bit longer than my forearm i think and she fits, curled up, on a little less than two hands if that makes any sense. anyway now I'm fretting over whether she's comfortable or stressed.

setup wise i have her in a 20g exoterra starter tank with one hide (i plan to get more), a water dish thats heavy enough not to flip and wide enough that she can mostly of not all the way lay in (i heard sometimes they like to do that?) and its partly over the UTH on the warm side. i have a UVB on the cool side and a basking light on the warm side- trying to keep t​he air temp up. i have the stock thermometer/hygrometer (sp?) on the warm side, a basic thermometer on the cool side and a digital thermometer with the probe over the glass over the UTH. i have the better digital thermo/hygro on order. oh i also got her a humidifier since i was having such a hard time getting humidity on point. i also put some foil over the top of the screen to try and capture some more of the heat and humidity and that did wonders.

like i mentioned, right now she has one hide on the cool side that she either coils mostly under (I'm starting to suspect she might not fit completely under it) or she lays on top of it half the day then lays out on the warm side sometimes too. she seems to stay pretty still during the day and gets super curious at night although this morning she seemed a little more restless. how do i know if she even likes that hide or if i should scrap it when i get her another or possible 2? also i noticed she likes stretching out and climbing so should i put things in her tank with height? should i be worried about her being to close to the lamps (right now the domes are just resting on the screen)

i read that for set ups with a tank i should cover 3 sides for her, does colour make a difference?

i was able to get the bottom of the tank on the warm side to a nice 90 but I'm having a hard time with the air temp bang btwn 80-85 (hence my using a basking light for some hours) but its a bright white light so i try not to have it on to much because i don't want to annoy or stress her out. any ideas? how much should i worry about air vs the bottom of the tank temp? she's got some basic aspen substrate, will she get the heat she needs through the floor with that? should i measure the tank floor on the cool side too (regulated at a cooler temp of course)? where exactly should i be placing any thermometers / probes? ill buy a hundred if it keeps my new baby comfy lol

I've been reading about RHPs but I'm not clear on how they are attached, I'm hesitant about anything with adhesives on her side of the tank. she's a real investigator so far lol. are RHPs crazy expensive?

also i keep her in my bedroom, whenever i go in there after hours (sundown) will i be stressing her out turning on lights and such?

as far as handling, should i only mess with her during her more active night time?

do you think scents like wax melts will stress her out? (i have some in my apt)

I think thats all my questions for now. Im so excited to have her, she's so friendly and beautiful. i just want her to like me lol and of course be healthy and relatively stress free.

thanks everyone who responds,
-the new guy
