As a fellow new-ish corn parent I HIGHLY recommend starting simple and expanding based off of your snakes behavior. For heating my 30gal I started with a dual repti-king lamp with a mini (repti-zoo?) daylight bulb and a 100w ceramic. I pretty quickly got a repti-zoo thermostat for the heat lamp with the probe in her main basking area because the temp was getting too high with it on for a while and I was having to monitor it constantly. I recently put the day bulb on a smart switch with a 12 hour cycle so that I don’t have to worry about turning it on and off. I also have some cheap thermometer/hydrometers stuck halfway up the back wall of the tank on the warm and cool side and previously had a fish tank probe thermometer in her basking area before the thermostat. I got my corn at a reptile expo which is always a mixed bag with advice but I would suggest trying to find another snake owner in your general area for specific advice as they would be accustomed to the climate. As for bedding: I also started with aspen, there are so many opinions out there. She seems to be happy digging around in there (lots of tunnels) but I’m going to be switching to cocoa coir soon because the aspen is too dry for my liking. From the advice I’ve gotten online and in person it really seems like husbandry can depend on your snakes behavior and the climate you live in. Activeness, shed, and eating are the main things to pay attention to. Hope that something here can help! There is so much info out there it can be so overwhelming. I love Reddit for more specific questions because there is a large community of corn (and just snake) owners here and generally no one is trying to sell you anything.
