When to start feeding new BP?

[Bogertophis]

Thank you so much for your response!
Here is my info:
I am using an UTH mat and a heat projector bulb both connected to thermostats on the warm side. The UTH is on the outside of the tank on the glass while the probe is on the inside glued to the glass.
The warmest ambient is 88 and the coolest is 74
The UTH glass spot is 86ish
84 in warm hide
74 in cool hide with 70-80% humidity


He’s burrowing on the warm side. I just checked and he’s back in the warm hide itself so no longer burrowing in substrate.


The thing I am struggling with is humidity regulation, I mist everything at least 2-3x a day. The cool side with no lamp stays at least 69% while the warm side can sometimes drop down to 50 which I try to fix immediately. I try to keep both at least 60.
I have a 20g glass tank with a mesh top lid and I use a mixture of fine coconut fiber and cypress mulch. I keep a plastic sheet over the mesh on the cool side right until it gets to the lamp. I try to keep a damp towel on the edge of the mesh on the warm side as well, I’m just not sure how to block the humidity in around the lamp.

Suggestions:
Only measure the inside temperatures with a temp. gun- For SAFETY, take that probe OUT- it belongs directly UNDER the glass, sandwiched between the UTH & glass. Reason? Your snake WILL dislodge that probe- because they use everything they can to hang onto (no hands ) & when the probe gets pulled free it's going to overheat that UTH- it will no longer be reading over the UTH, so the UTH will be going full blast trying to bring the temperature up until you discover it...which may be too late to prevent disaster. Overheated UTH can burn or cause neurological harm to your snake, or it could short out & cause a fire- you don't want either one.

The temps. sound good, but for humidity do not mist...it's not effective & stresses your snake (going from too much to too little). Instead, add some moisture (now & then as needed) to the mulch, provide a humid hide (if you want & if there's room) and most of all, cover that screen top as much as possible with aluminum foil*. (Leave only small gaps.) The heavy duty foil will hold up better- just cut out a circle where the lamp goes; you don't want meltable plastic near a hot lamp- foil is much safer (it also doesn't off-gas like warm plastic does). LOSE the moist towel, it's not helping- air goes right thru it, & humidity along with it. 70-80% humidity is only acceptable for when he's in shed- otherwise it's too high -you only need about 55-60% all the rest of the time, & don't worry about some fluctuation between the warm & cool side. *If you want something sturdier than aluminum foil, some have plexi-glass cut to fit, or you could use sheet metal. Various materials will work (block all air flow) but you want to use something that's not too heavy- for convenience. But for now, foil is easiest & safest & cheapest- it will do the job. (not saying it's the prettiest)

Overall, you're doing quite well- you've just about got this, okay? We know it's a challenge.
