I mean I love your suggestions but I think my suggestion was really valid, but probably too expensive unless you were providing an actual service to help cover initial and annual costs. Web storage is a booming industry so it's not like this would be impossible.
I mean if I'd start a business I'd probably just start the grow op as my business and say forget all this bullshit. But if I absolutely had to covert grow for some reason I'd probably want the business to actually be a business as best it could. That in itself would be less suspicious.
