The 99-plant growing limit previously established in Colorado statute was far higher than any other marijuana state in the nation. Sponsored by House Majority Leader KC Becker, D-Boulder, supporters of House Bill 1220 believe that reducing the residential growing limit to 12 plants can help law enforcement agencies better deter black market growers, investigate massive, illegal operations and protect neighborhoods from potential public safety hazards and decreased property values.
The violent crime rates in Colorado have dropped since the state legalized marijuana. But some illegal operations have exploited the lenient growing limits, as discovered by recent law enforcement stings. These busts showed some illegal operators have conducted large growing operations in Colorado and then move the marijuana into the black market or across state lines where profit margins can be much higher.
