I will start to do the same thing with 9.2l air pot ( thats the size that i find in my country) in a same dimension box, for sure with regular seeds/clones it will be great with a good airflow at the pot level cause they will take like 90% minimum of the grow area . With autos all stays in genetics and abilities in my opinion. Thats my opinion, probably I will start with an auto grow meanwhile some mothers grow, so I will know much about this topic in a few months.
Sorry for my bad english, hope that comment will be of some utility
