I agree with flight. As long as it doesn't say "I grow pot" you shouldn't have a problem. I ordered most of my equipment online, and a couple things weren't over boxed. However, I live in a medical state and am following state law, so I don't stress it. Thats one thing ive learned in the last 3 months. Just stay cool and let them grow. And sure the UPS guy can come back and check what I'm doing with my 6" inline fan, but he saw my dog trying to eat through my glass door to get to him when he dropped it off.
