I have spoken to several licensed caregivers as well as patient caregivers, and it is to be expected that spikes in power output will occur during your grow period. Here in Michigan, DTE actually has an addendum which allows you to notify the state as a licensed grower, which will avoid "local calls" for such occurances.
As stated previously by another forum member, since the law was passed there have been individuals who seek to take advantage of growers and patients, because all these people see is the street value of the meds. The law in michigan is still so grey that you just have to be careful of who you let know that you're growing.
