The Fresno Bee reports ( http://bit.ly/1jIi6yR) supervisors approved the penalties at a hearing Tuesday.
The ban, which took effect in February, calls for fines of $1,000 per plant found at residences.
A Kerman area man was fined $30,000 for having 30 marijuana plants in his garage.
A woman from Manteca was hit with a $43,000 fine—$1,000 for each of the 43 plants found at her mother's home. The newspaper says her mother could also face penalties through a property lien.
Fresno lawyer Brenda Linder calls the fines "exorbitant." She says she will seek a temporary restraining order to stop the county from continuing to go after small-time growers.
