Stoney is right. You want to know what happens in a cultivation bust?
1. they go in freeze all accounts of parties involved. They start auditing to see if profits were being made without taxes. It is hard for an honest person to validate all purchases and income during an audit. Most people have nervous breakdowns during one.
2. They seize all assets that may be linked to a grow. (this you have to prove and its difficult). TV's, Computer's, etc.
3. They put minors in "protective custody" until an arraignment.
4. Each state considers one living pot plant differently. whether by the amount speculated it can produce, or the actually wieght of the plant (including soil).
5. Your parents will have thousands of dollars worth of attorney fees and court costs.
6. One if not both of your parents will end up with probation or going to jail.
Depending how good the attorney they can afford. Just like anything you get what you pay for and good attorney's aren't cheap.
I know at a young age, you parents don't seem to cool. but if they have rules about pot and pot cultiviation, it is because they love you and don't want you screwing the rest of your life up. You could lose your chances to govt. grants, loans, jobs, all sorts of stuff. Plus the trust of your parents for many, many, many years to come. It would negatively alter the relationship for the rest of your life. That is a ton of guilt to carry with you.
If you have to grow. Outdoor grow in the woods. Then it just your ass. Sorry dude, but I am a parent. I wouldn't appreciate my kid growing behind my back and putting me in such a fucked up position. Actually I don't care how old they are. Even 25 yrs. old. I would tan their ass for betraying my trust like that. Wait until you have your own place and your own ass is on the line. Besides it took me until I was older to truley respect the risks of pot cultivation. I am a paranoid old fucker now. I don't let anyone in on my grow.
