Pot Size for Outdoor Autos

So I'm gona be growing 6 femenised autoflowering plants outdoors in southern California. I heard square pots are best for root development so I ordered some online. I also heard more depth than width is important. My pots came and I'm thinking that maybe they are too big to pot in because I've heard people say you don't wana plant germinated seeds into pots that are too big. So I got thinking and I'm wondering how can any pot ever be too big? I understand if it's too small but how can a pot be too big, I read something about if the pots too big the plant will use extra energy developing roots which will stunt growth above soil, but how the fuck could a seed know the size of pot it's in unless it's too small?? Anyway the photo attached is the pot size what do you think is this too big or should it work good??

Thats not going to be big enough for outdoors. I am running 15 gallon smart pots in the Eastern Oregon sun and I am worried they are starting to get root bound. All my girls are few weeks into flower . As far as the planter being to big to start a seed. No it is not. Think about the plant in nature. It is germinated in the EARTH the mothership of all planters.

I think, the only way a pot can be "too big," is if you procure significantly more soil than your roots can actually use during the duration of its full life cycle.

Then again, no cannabis plant has ever managed to fill all of earth's soil with roots and become root bound, and i don't see that negatively impacting any of the plants which grew as big as nature would allow.
