worried || Temporary enclosure due to delayed tank + soil

[muse13]

Hey, I recently ordered a millipede (giant chocolate), as well as soil/substrate + tank alongside The issue is that sadly the soil and tank was delayed to come next week to come, is it find for the millipede to have around an inch of soil depth temporarily for a few days? The habitat is currently in very small too 4x 4 x 4 I could swap to a bigger container but the soil depth would go down as well so not very sure what to do

Yes I plan to fix everything up once I have everything arriving, I’ve to look around town for organic non-fertilized soil same day, but not many options with many being very heavy big bags. I just worry the small amount will lead to something bad 🥲 And I did order the soil a week before I did my millipede order, it sucks
