Customs is a federal thing. If they are going to go about setting up a raid it wont be over small stuff. For the most part raids happen because of loose lips, being a dealer, stealing electricity or using an ungodly amout from having a big grow, the stench of buds outside, or evidence like grow supplies visible, trimming in the yard waste or something else. Busting registered medical growers is easier than a seed buyer. A couple weeks from them passing there might not even be sprouts. Cops want results, awards and recognition. Not bust a shmoe woth a couple plants or for ordering seeds. If locals bust you itll be from your local post office turning you in which isnt likely. Most seeds are shipped stealth amd if not I wouldnt order from them personally. Ive been around forums off and on amd all the busts I have seen were dealers (grows to big to be personal) and med patients.
