I'm unfamiliar with the outdoor, honestly. I've never had the opportunity until now. But I'm sitting this summer out as far as outdoors go I think. Not certain just yet. I've missed the planting mark to some extent. I'd say largest pots you can swing man! Like mandala says, step up in pit size clear into like week 2 of flowering if needed. Good soil, nice amendments, quality organic food (I prefer vegan ingredients). I'd also say follow mandala instructions, as they know what's up with thei genetics, and advanced/basic growing.
