How's my Setup?? + I Need Advice!

[klevert]

I procrastinated making this post because I'm bad at taking criticism, but here's hoping most of it is constructive.
here's my setup for my 6-month-old BP:

The Specs:

• 40-gallon exo-terra tank

it has a mesh top that didn't hold heat well so i have Super High Tech aluminum foil-covered cardboard rectangles that fit into each one so they hold heat and humidity better but i can take them off to clean & regulate

• 100watt CHE

does its job reasonably well, I have a very DIY'd set up for it because it doesn't clip to the tank but it works. i don't have it on a dimmer but it seems like it BARELY keeps the ambient temp up so do i need a higher wattage on a dimmer?

• Probe Thermostat #1

measures the ambient temp and humidity. i have it stuck to the back center wall and it usually barely hits 80. is that enough?

• iPower 16w UTH

covers roughly a third of the bottom of the tank. plugged into two different thermostats (see below)

• Probe Thermostat #2

Measures the UTH on the INSIDE of the tank. stuck to the floor directly over the UTH so i can see how warm it is once it gets through the glass.

• Jumpstart Thermostat

what the UTH is plugged into. i keep it on the highest setting (105) because the heat that makes it through the glass only gets to about 95.

• Water Dish

technically it's a food dish but whatever. I keep it directly under the CHE to help with humidity, and near but not precisely on top of the UTH. the water temp does not get hot but it helps with humidity.

• Warm Hide

Rock hide because it holds heat better than the plastic ones I tried. plus my BP seems to boycott plastic ones (maybe because of heat)

• Cold Hide

big fake log. that's it. he likes it and i like it.

• Coco Fiber Substrate

sometimes he eats some of it when it sticks to a mouse but it keeps humidity reasonably well.

• Sphagnum Moss

for humidity. but damn it's hard to spell.

• Various Leaves n Decor
• Coming Soon: going to add a beardie hammock because he thinks he is a tree python.

I know it isn't a fancy set up, but is it okay? I struggle with keeping the heat up enough in the winter but i'm not sure what I should do to combat it. I have emergency snake funds set aside but I am on a budget so I can't just keep buying things looking for something that will work. is 40 gallons enough for a young BP? he's 6 months old now, and I really probably just need to get a year, year and a half or so out of it before I can move into a space where I can fit a larger tank.

also, on the subject of heat: is it warm enough? the UTH usually gets about 95 regularly, but that's under the substrate, and I worry that it doesn't get that warm in the hide enough though I keep the substrate under there pretty thin. should I find a different thermostat that will let me turn it up a little higher? if so what kind? is the CHE a high enough wattage, because sometimes the ambient is only is the 70s....

please critique!!
