You mean what is the verdict on - 1 package in a thousand is discovered and those get pulled and replaced with a letter,.. and of those discovered,.. and depending on where you live,. 1 in a thousand get a phone call to the local PD,.. and 1 in a thousand of those phone calls is to a cop who is so bored he decides to make something out of it.
Of course those aren't the real numbers, but I say the odds are pretty slim anything happens at all. You have better odds getting pissed that the bank you ordered from forgets to send you the seed, unless you order from someplace with a good reputation. Think of the tens or hundreds of thousands of posts on various internet sites over the years and the percentage of those who had seeds confiscated.
Rollitup wouldn't be here if the banks didn't know how to mail a seed.
Get it stealth, and if you use a different name, realize your post office may send it back,.. may not. If they do, the reputable banks will refund or resend. Be patient,.. be happy.
On the subject of bag seed,.. if I grow diesel and give someone an ounce and he gives someone a quarter and they give someone an eighth,.. that dude probably ain't gonna know the strain,.. smoke it and say, damn best bag weed I ever smoked,.. might find a seed,.. grow it and say,.. best weed I ever grew was bag weed. My point,.. you don't know what's in the bag and if it was awesome, I see no difference from growing that versus the latest cup winner. Who cares about the genetics at the end of the day. If it's a great high, great plant and yield,.. what the hell does it matter if you know it's name?
