Well the Supreme Court grabbed a whole chunk of federal power with this decision[1] that pertains to the exact situation you describe, albeit on a larger scale.

Well the Supreme Court grabbed a whole chunk of federal power with this decision[1] that pertains to the exact situation you describe, albeit on a larger scale. The short of it is that even if you grow something for your own use, the Court's opinion is that still affects interstate commerce. > Filburn argued that since the excess wheat that he produced was intended solely for home consumption, his wheat production could not be regulated through the Interstate Commerce Clause. The Supreme Court rejected the argument and reasoned that if Filburn had not produced his own wheat, he would have bought wheat on the open market. Good ol' Interstate Commerce Clause strikes again.
