autos in ground?

Anyone try autos in ground? I always see people doing them in pots outdoors, and wondered why not in the ground?

The largest auto i have seen was planted in the ground. Topped out aroun d 7'. I suggest digging a whole and adding a bag of soil with lots of perlite. Go with FF or Roots Organic. Once she is rooted nicely in that stuff the roots will expand until harvvest. The saying is bigger roots=bigger fruits. So i say go for it.
