“It’s legal now to have 12 plants in your home,but the advocates understand that this is likely to be debated in the process,” Rosenberg said. “According to the people who know a lot more about this than I do, they say that for someone who knows how to truly grow these plants and once you master it — which is not all that hard — 12 plants would produce about 30 marijuana cigarettes a day.” He added,”I mean it’s just it’s a very large quantity to have in your home at any given time.”
Asked to clarify whether the Senate president supports a reduction in the number of plants that can be legally grown, a Rosenberg spokesman said the Senate leader is “still doing his homework and will await the recommendation of the Marijuana Committee.”
Peter Bernard, president of the Mass. Growers Advocacy Council, said Rosenberg’s estimates do not jibe with his own experiences as a medical marijuana grower.
“The reality of it is that the average single home-grown plant is going to yield one to two ounces. A talented grower could maybe get four or five ounces out of one plant, but we don’t have a lot of those in the commonwealth,” Bernard said. “Most of the people who are going to try this are going to try and fail. Those who do succeed will average about two ounces a plant, and it takes about six months to grow beginning to end.”
So, Bernard said, someone cultivating the current maximum of 12 plants in their home may be able to produce a few pounds of cannabis over the course of a year.
“If people think 12 plants will fuel a criminal enterprise — sure, they maybe could make a few bucks off friends and family — but it’s just not realistic,” he said. “Twelve per household is not unreasonable.”
Jim Borghesani, a spokesman for the Yes on 4 coalition, told the News Service that the groups that worked to legalize marijuana “adamantly disagree with any attempts to reduce” the number of cannabis plants a resident can legally grow.
