Home growing is becoming a big business in Massachusetts. At NECANN vendors were selling light kits, grow tents, soil and cultivation kits which can run from a few hundred to a few thousand dollars.
In Massachusetts, it’s still illegal to sell marijuana without a license. The law sets the limit on how many plants you can grow at six, or a maximum of 12 if there’s two people in the house. The plants must also be under lock and key and must be grown in your primary residence.
