i guess an incubator and a hatchling rack to later get the hatchlings started will be most important.

but ive seen breeders with modular or custom terrarium designs. in Germany, because we have minimum husbandry requirements that make modular terrariums / stacked terrariums useful, and in the USA ive seen it with breeders that deal with bigger snakes, like retics.

so that may vary. just breed them in the enclosure of the female. But incubator + hatchling rack are pretty much universal everywhere.
