I dont know what your laws are like where you live. But here Yes you can get arrested for having clones or any pot plants, even yours.

Where im from, If your growing for personal and you keep your mouth shut you'll be fine. But if your growing for commercial your in trouble, or if your growing for personal and your forcing to cops to come down on you (aka. big mouth,growing in public,basicaly being retarded) then they'll come after you because they have to.
If someone reports a grow op they cant really ignore it.

SO if your worried about getting busted, keep ur mouth shut, just grow it in someone else's house lol.
