There is nothing to go 'over my head'. Maybe the guy's hobby is growing tomatoes. Everybody isn't broke and folks will spend a lot of money on their hobbies. Fact is that you don't know the circumstances any better than I, but you want to defend the police state.
Just because you can't see doing it, doesn't mean others don't get it. Somebody should not draw the attention of police for doing something and buying something that is perfectly legal, especially when there is so much illegal activity that draws a blind eye.
My wife has all kinds of things sprouting in our little greenhouse in the basement with the fancy grow lights - even those awful things she eats.
We save a lot on money on sets in the spring and give away or sell the excess. Helps pay for our gardening addiction.
