if you want biggest as you can go i would suggest starting with feminized seeds or clones so you dont waste your time.
you should start them inside now and not put them outside until you know there is enough light so they wont flower to early..
dig a hole in the ground and fill it with good soil asap get your spot ready and then in a month or so you can put your lil girls out and they should explode.good luck.
by the way im a new grower kind of a newb but just to let you know it dosnt seem very hard at all to get a pound per plant if you have a 6 month grow season
