Super soil as a viable choice for a large scale grow?

I'm putting together the largest outdoor grow I've every thought of doing, 100 gallon containers and 100 plants. I was curious if any experienced growers have attempted to premix super soil in a cement mixer for a larger grow and if they felt like it was viable to do so. If its not viable, any suggestions on a mix that makes any more sense would be appreciated. What other soil mixes have you used outdoors besides super soil, and what were the results.
Thanks for the advice

I use amended aged manure. Much cheaper then soil and the growth rate just blows my mind. All the hay mixed into it too makes it have super drainage.

If you are in Cali or any of the other rec states, your local nursery will have some soil choices in bulk. Mixing 10,000 gallons of soil in a cement mixer is going to take a while. Time is money.
