Planning on buying my first hognose!

Hey there! I'm planning on buying my first hognose snake and I'd just like someome who has some experience to look over my current plan and see if there's any tips you'd have for me!

Terrarium: 200cm(length) x 65cm(depth) x 40cm(height) with integrated heating (found used).
Substrate: ~8cm of dirt mixed with sand (70:30) (is there any specific kind of dirt that'd be good or can this just be your usual backyard dirt?)
Spotlight (dragon sun-spot) with a cage for a basking spot on the left side.
6-14h of TV5 UV-light a day
A patch with wetter soil on one side to keep humidity up
landscaping with plenty of stones and some fake plants as hiding spaces
Thermometer and Hydrometer to keep track of everything.

Am I missing anything crucial? going overkill on anything? Are there any better products I could be using for spotlight or the normal light?
