Billy, you're absolutely right. The definition cited were stripped before implementation, so it's sort of the wild west. The State Constitution says retail marijuana and home-growing is OK, but the statutes haven't caught up on the home-grow stuff yet. They were set to do so, but that's not what was ultimately signed into law. Of course, the State Constitution trumps the statutes, so any enforcement of conflicting statutory provisions is plainly unconstitutional.
The upshot seems to be, though, that home grows are
not really regulated. You can (because the Constitution says so) grow six plants, with three flowering. You can (because the Constitution says so) possess up to an ounce.* You can (because the Constitution says so) possess, display, etc., "marijuana accessories" such as pipes, bongs, oil rigs, and such as lights, nutrients, pots, etc..
Of course, the Constitution does state that growing must "take[] place in an enclosed, locked space, is not conducted openly or publicly, and is not made available for sale." Though those terms aren't defined in the amendment or statutes, it'd probably be wise to not test the limits. While you may escape conviction, you'll still be out many, many hours and many, many thousands of dollars in legal fees. And, that's assuming your locality hasn't adopted local laws defining those terms, which may still lead to a local conviction. To be safe, check your local laws for definitions, and keep things "enclosed" and "locked," which likely means a roof, a floor, and four walls (though the material's not specified, so it could be brick, fence, twine, who knows...); don't grow "openly or publicly," which likely means indoors or behind a privacy fence (somewhere you have a reasonable expectation of privacy -- back yard versus front yard, for instance); and don't sell, which likely means don't sell.
Cheers!
