Hello,
I suggest you to google it because every states have their rules with herb. If you already start thinking; If i get caught... Its not good for the karma
Usually the key is;
-Do not tell anything about your grow even if you have the sexiest plant in the world.
-Do not brag about how a good grower you are or how your weed is more killer than other weed.
-Never post pictures online that show your face, proof of who you are (take care of reflect on your reflector on the wall or any glass that could show your identity)
-Never post pictures that show too many plants and rooms (That what LEO aim)
-Remember this; You re best friend can be you re worst ennemy under jealousy. If they are jealous of what you are doing, you can be fucked. (Which make my first point more important)
-Do not think about the negative side of this hobby (Cops, Neighbour who might spot you) Just do your thing, act like you used to act before. Do not be nervous and nothing will look suspicious. If someone knock at door (ie: your stuff is down stairs) do not act like you hide something.
and again the most important; KEEP YOU RE MOUTH SHUT!
Have a nice day! Hope it helped!
