Soil Grow WW auto

I want to grow these WWauto I got so going to do soil. I never did soil I got my hydro dwc going ATM with my road runners and just felt like doing a little more.

First I need to know soil to use someone told me use this: http://images.lowes.com/product/converted/025849/025849202019lg.jpg
Yes or No

Since I am doing auto and I hate transplanting I will be purchasing a 5gal x3 or just use a tote I have for all 3.

i already know no nuts till at least 4th week. I already have ph water from my dwc resivor ph to 5.8 I don't know if soil need higher. Please point me in right direction in u know a forum containing information already. Or if u want just tell me. With my dwc light are running at 18/6 so I will just throw soil under that and I also know that I will have to cut holes for drainage.

one more thing should I soak seeds for 12hrs in rooting sol. Or should I just plant when I get soil and give it water and see from there.

Ideas, comments, and critism is welcome. I'm here to learn.
Thank You

Damn not one reply no help I guess I just got to go out and try.

I am personally using that exact same soil for my grow, you can take a look at my journal and see my plants. This is my first grow and I had good experience with the pro-mix so I'm going to stick to it.

As for germinating, I use the paper towel method. You should always germinate seeds, so that you can be 100% sure they are good seeds.
