Jayfury not sure which of the states your in but heres the deal. All medi grows are technically illegal by federal laws. States who have med cards are just basically saying ok we will allow it but we can arrest you for it if we want since the fed laws over power state laws. Some cities will allow it but the county mor state troops may get you. Now these states each have their own variation. in cali a card member can grow outdoors with proper papers so what your saying is only correct to your case but even if your in a so called legal grow state the feds, state, city or county can still bust you at will since it is a federal crime and they can enforce it. That said the case is now in front of the Fl supreme court and now the federal supreme court. Cops have been allowed to walk dogs up to your door and look for a signal then get a warrant and kick in so thats legal as of today in most states. If his neighbors saw them and complained the local cops would more then likely not come right away but would start snooping ie looking at garbage at the curb as that legal for them to do.. They may watch traffic at the house...They may stop by on bullshit like looking for some fake person to get an eye from the door. They may also come asking to come in and look due to a possible complaint. Kind of depends on the area and what the norm is. A complaint is enough to get the ball rolling so yes be cautious.
None of this is disagreeing with what I said, except you dont believe a search warrant would be given. I am in RI, and here, you cannot grow outdoors. Cali, yeah you can. Obviously it varies from state to state... Obviously it is Federally Illegal, Im not retarded... The feds wont bother you if your in compliance with state law.... USUALLY.... Sometimes they do bother you. Maybe Im a little bit more educated in the law od warrants because I went to school for Criminal Justice, but I can guarantee this..... If your not in Cali, and your growing outdoors, and someone sees it and decides to call the cops.... Expect your door to be knocked on minimum, but I bet you will be looking at a warrant.... They will get the warrant on the grounds that they "dont know" whether its a legal medical grow or not... Kick down the door and wreck your shit FIRST, ask questions later....
