Hello
Doing a sea of green would be a fun idea and use the space nicely, also small pots are easy to move. Personally i would do the sea of green using some photoperiod strains, especially if you get cloning, then you can make a sea off just a couple seeds. If your sweet tooth is photo you should snag 6-8 clones and veg them like 6 weeks and they might flip naturally with the season change.
Otherwise if you did autos, germinate multiple seeds and then keep them in 1 gallon pots and line the porch with like 6-8 plants.👍
