Sacramento County is looking to limit the number of marijuana plants people are allowed to grow indoors. 

The Board of Supervisors unanimously voted to ban outdoor marijuana growth two months ago in response to safety and nuisance complaints. 

Now, a new ordinance allows for indoor growth of only nine plants in single-family detached homes, and they must be concealed from the public.

County supervisors say the restriction still acknowledges the needs for patients.   

However, marijuana advocate Bob Bowerman argues nine plants won't be enough for the patients who are the most sick. 

He says the nine-plant limit would allow patients to have one ounce a month at best, but he knows people who need an ounce or two a week.

The county's ban on outdoor pot gardens is already in effect, while the indoor restrictions won't go into place until mid-July.
