Food for the thoughts, patience goes a long way but maybe the impatience is due to the fact that the purchase was made first and questions ask lateradditionally while 50 people may have viewed that thread it does not mean that they know anything about hognose.
Now to the answers
I keep hatchlings until they reach 10/20 grams (depending on how they do really) in pencil tubs (see C-serpent rack http://cserpents.com/C_Serpents_Hot_Box/Colubrid.html) , when I only had a handful of them I would keep them in stand alone 2.7 modular latch box tub https://www.walmart.com/ip/Sterilite...-Unit/55413807 (How big or small will depends on how good of a feeder the animal is, (they can be tricky if not well started or fully converted and or if their needs are not met)
from 20 to 150 grams I keep them in V18 but 6 quarts tub will do as well, after that they are ready for their permanent enclosure 20 gallons tank or V 35 S tub or sterilite 32 quarts tub.
Over the years I have changed things around but this is how I keep them now.
Tempertures I have experimented for several years and like BP I do not keep Hognose as hot as I used to however for a first time owner I will recommend slightly higher temps 80-82 and 90-92
