m0useanswered grow question 2 years ago LOL get rid of them asap, all equipment and paraphernalia too if its illegal to grow.
If its not illegal to grow, then you have nothing to worry about.
If the cop cared to bust you, that "seeing the plants when you opened the door" is enough for them to act on it right then and there, they would not need a warrant. So ask yourself, how certain are you that they saw it and if you think they truly cared at all.
Cops here didn't give two fucks if they saw a random plant before it was illegal. Different story if someone calls about it then they are obligated to follow up.
Be on the safe side and relocate it all to a buddies.
