Yo Ho lemon breed08,
Slow up for a few moments and allow your brain to function. Eighteen plants is cool, but it's not going to be the end of the world if you lose them.
It would seem that there are a few questions as to how all this happened, and in time you will maybe find out what gives, maybe you won't.
Let's say leo shows up at your place, and you get hauled off. Don't say anything without a lawyers advice period.
I looked up the laws in your state with regard to possesion and/or cultivation you can find your answers here hxxp://norml.org/index.cfm?wtm_view=&Group_ID=4544
First don't panic or freak out over this. Each minute that passes works in your favor. Yes prints do degrade, and you can always play dumb as far as the rest of the world is concerned.
The big thing in all this is for you to realize that your young and you can always start another crop in another place, in another time. So really what is there to worry over.
Give it as much time as you think that you need to give and take your dog if you got one out for a stroll passed the spot. You can always deny any knowledge, and just say your walking your pooch, or looking for a stray cat that went this way, and you felt sorry for it and thought hey a good pet if I can get near him to see if he is tame. Bring along something a cat would eat.
I rather lean towards the idea of starting over, only this time
TELL NO ONE.
Good luck bro, let us know what you find out, and in the meantime we'll keep up some good thoughts for you.
smoke in peace
