not that it is smart or advisable but two out of the three previous residences' I've occupied and grown out of had seeds sent there on multiple occasions. Actually a lot of my gear from beans to ferts that wern't locally available to my 1000w with 4ft hood and ballast came to me in the mail, and that was years ago.
Nowdays I would never order a light to my place, but beans I'm still tempted to, just to ensure no tampering by the party potentially receiving them on my behalf.
As for ferts... find me a place locally where I can get
biobizz gear and I won't use the net anymore.
Again its NOT smart and NOT adviseable. But I have yet to see detriment from it here in the states on my end at least. and this is so far, I suppose.
Between my fits of paranoia I subscribe to the 'thumbs up their asses' theory. That a few things in the mail are far two small to notice in the grand scheme of things. Sort of like small personal growers being not worth the time and money of gov't agencies. I'm fairly sure (though don't quote me on this), as long as you don't sign for it, or admit to anything, the worst that can happen is you get the infamous green letter from customs informing you to go pick up your withheld goods, which you don't do, so they destroy it. end of story. as far as I think I know. again I'm likely wrong.
However if you do sign or do admit to having something shipped to you or they come to your door and you don't know your rights and how to assert them then there could forseeably be an issue.
It is a fact that people have been busted after ordering gear off the net of any kind, and this fact certainly causes me to second guess myself often. So far though, so good... knock on wood.
