Hi,

Sorry if this topic has been discussed before but I haven't been able to find it after carefully reading related sticky posts about setting up tanks/tubs.
I noticed that most people here is living in a country with 4 seasons, hence the need with all the heating lamp, UTH etc. Now, I live in a tropical country where there are only two seasons, dry and wet and generally very humid.
This is the first time I keep snake as pet and I only got her, 4-5 months old female pastel ball python named Bally, because of my daughter. I've had her for a month now. Since then I've feed her five times, pooped three times and so far she's a playful and active snake.
The first time I got her, the pet store guy just told me to put paper/paper towel and a bowl of water inside the tank and assures me that I don't need anything else. Since I got her home, I've search plenty on how to properly care for a ball python and stumbled upon this site. I've made adjustment for her tank, using substrate, covering three sides with black papers, getting half log as her hide and put thermometer/hygrometer inside. From a week of observing, the temp is around 77-86 F with humidity ranging from 70-85%. As far as the snake, she seems fine to me. Curling up inside her hide mostly, peeking when she's ready to eat again (usually 3-5 days after feeding), drinks, actively slithering or just curling up the hand when put outside, never hiss and never strike.
Now my first question is, do I still need to put heating source with the climate I live in? I can't find UTH in here, I've tried looking both in pet store and hardware store with no success. If it is still necessary to put heating source, what is the alternative safe way of UTH? Heat bulb?
So far I've only put one hide inside her tank because there's no hot/cold spot. It's half log, when I tried to change it to smaller opening hide, she just roamed around it so I put the half log back and she slithered right in.
Next is how to lower humidity inside her tank? The highest humidity I found was 90%. To reduce, I usually open the top lid and change her substrate in two weeks or whenever I found it to be damp and/or smelly. Do I need to change the lid? If you have better way to control humidity, I'd really appreciate it. Just so you know, I remove any excrement (spot cleaning) as soon as I found them, be it urates or poop.
Since snake is nocturnal, does it mean that it's better to feed her at night? handle her at night? or is it just fine whenever? So far she doesn't seem to mind if we handle her in daylight, no hissing, no S shape readying to strike whatsoever.
Oh, she had her first shed, well since I brought her home at least and it was no fuss (I was worried about the shedding process), I just woke up and found her old skin bundled up in front of her hide

Here's a picture (no filter) of her with new skin:
