First time Outdoor grow 14 With Super Soil

Someone help me get a few things str8. I'm going to be doing a outdoor grow and I have a few question.

How big of a pot do i need for a grow this summer (NorCal) 15,20,25. (Plan to get my Clones around May 15 or so) and what size Pots do i put my clone in when I first get them(Red Cup to 1 gallon to 5 gallon then 20) and do I need to use the Super soil method right from the start when i get my clones(1/3 super soil 2/3 base soil)?

Let me know. I don't want to burn my plant if I don't have to use the super soil untill I transplant them to the bigger pot.
Also will the super soil last through the whole cycle till October?

If any one has the answer to these question it would help me alot.

I would say yes to the pot sizes you could even go from a solo cup to a 2 gallon then to a 20 gallon that's what I do anyways I go from 1 gallon to the ground tho lol. But as long as you don't use for you should be fine stuff seems to be hot. I normally just use happy frog and I use that soil and only thay soil when in pots. And it should be enough nutrients in the soil to last a few months If you do it right. You can go from a Dixie cup then soil in a 1 gallon and about 3 weeks later transplant add more soil(more nutrients in soil) till its in its final resting place and about 2-3 weeks later your gonna wanna start feeding them with veg or flower nutrients. Hope this helps some FYI I'm no pro that's just how I do it myself everyone has there own ways.
