Hey there! Glad you found us! I don't know what's going on on Reddit... everyone seems to praise the advice of one new keeper... sooooo yeah.
My problem with 40g tanks is that they are suuuuper tall. Think about the volume of air inside the tank that you need to heat and humidity. It is quite the task.
A 170g snake in a 40g is a bit overkill in my opinion. Have you considered a tub setup or a pvc enclosure? PVC is a little more expensive, but so much easier to keep temp and humidity where they need to be.
Perhaps you could use a tub setup until she is a bit bigger and then move her to a permanent PVC enclosure.
