what size pot do u recommend for outdoors

At very least 15 gallons, and as much as 200 gallons, its way to late to start though unless you put your plants outside right now.

How big do you want the plant to be?

Good question and good aswer btw.. Pot size is kinda like light. Ya can't have too much and it can't be too big unles it doesn't work into your plan. It helps to know what you're trying to accomplish. Also if you're not is SC then you are no doubt too late for this year.. SC in a greenhouse? No prob.
