Soil for commercial use, for and against

hey guys.
new to group, so good to be here with like minded folk.
I’m putting together a business plan for a large scale commercial grow and I’ve been toying with hydroponic vs soil.
ive always used soil and have made my own super soil for years. however going from medium home grow to large commercial i now seek advice is to whether this is the most viable option.
has anyone done 1200 plants in soil here, if so can you let me know your product storage methods and supply of where to get that much fresh soil, also dumping of used mix etc.

thanks heaps guys!!
