Yeah, they wont send you to jail for a grow sheet. Can the send you to jail for having a book that teaches you to grow or a grow video? Sure, getting caught with a grow sheet alone does not help matters but unless you have child porn on that grow sheet you will not even get probation.

If you get caught with ferts meant for Marijuana, grow equipment and so on and the cops know 100% you use to grow, they still cannot arrest you for that alone. They need to catch you growing or with Marijuana
