Outdoor grow op tips?

[Cannaseur]

So it's come to time where I decide that I should let go of the hydros and stick to the dirt.
Me and my team found an extremely beautiful place to grow about 10 to 15 plants.
Any help or advice recommending on the soil and other supplements that is best for outdoor growth?
Price doesn't matter for we bring the most cash to get the most stash %)

Thanks,
