I've read this whole thread and I get the feeling that you have never grown before and have no idea of what you are trying to do.
I read all the plant problems that are posted here. You should take a look at some of the problems people have growing a single plant. Those problems are faced every day. If you are serious then you need to do a small grow and see what it's like.
It you try growing that much I can almost guarantee failure. No amount of advice will take the place of experience. You will need to be able to look at a plant and know what it needs without looking up each problem.
I know that a lot of growers think that growing in the ground is a sin but I grow in amended native soil, was 12 plants now 11. One was a male. Before I found it it pollinated the plant next to it and I hope that's all. That's all you need on a big grow like that to ruin your whole crop. Don't try to convince yourself that's not going to happen.
