Light dep vs indoor plant spacing?

I've searched and come up dry so if this has been answered someplace else before forgive me but I couldn't find it. I've never grown outdoor and was wondering if one took 4 plants vegged to the size of filling a 4x4 indoor space once flowered how much space would those same plants need in an outdoor light dep hoop house? Same? 5x5? More? I know conditions, soil, strain, etc, can change that some but I'm just looking for ballpark rough idea.

Yes I know I could grow them way bigger and it would be way less hassle without pulling tarp but I'd rather actually get a harvest then it all go moldy from the humidity going sky high in the fall.

5x5 seem plenty to depo but they will explode with real sun couple layers of net to tame them.

When I plant fem seeds, I put my plants at least seven feet spacing. Anything closer you will reduce yield. These plants get 6 feet wide at the base for an average size plant. You don't want them crowding each other. I had a huge plant last year that was 8 feet dia at the base. When I plant non-feminized seeds, I space at 4 feet, expecting that about half will be males. This leads to problems, so I use fem seeds outdoors, now.

Molds a bitch, my first couple outdoor seasons I was terrorized with it. Airflow is key some strains can handle it better than others
