The plant counts people get wrong
The tempting arithmetic is multiplication. If one adult 21 or older can grow six plants, the thinking goes, a house with four such adults can grow twenty-four. It cannot. The allowance belongs to each adult 21 and older, but the home has a ceiling of its own, and the table below shows where it stops the count.
The other misreading treats the allowance as any six plants. The counts come from chapter 420b of the state's General Statutes, which splits the allowance: each adult 21 or older may grow up to three mature and three immature plants, so six mature plants for one adult is twice the mature allowance.
How the household cap works in a real home
The cap only changes the answer once a third adult 21 or older lives in the home. Here is how the count plays out as more of them share the same primary residence.
| Adults 21 and older living in the home | Their allowances added together | Most plants the home can have at once |
|---|---|---|
| One | 3 mature, 3 immature | 6 |
| Two | 6 mature, 6 immature | 12 |
| Three | 9 mature, 9 immature | 12 |
| Four | 12 mature, 12 immature | 12 |
Two adults 21 and older reach the household cap exactly, because their two allowances come to twelve plants. Each one after that brings an allowance the home has no room to use.
Where the plants can and cannot live
The statute sets the counts. DCP's plain-language article on growing cannabis at home sets the conditions on location, and it is worth reading in full before you set anything up. For location, the conditions apply together: the plants are in the grower's primary residence, they are grown indoors, and they cannot be seen from the street. Most spots in a home land clearly on one side.
- A spare room or basement where nothing shows through a street-facing window: passes, provided the under-21 condition below is also met.
- A sunny front window: the plants are inside, but if someone on the sidewalk can see them, they fail DCP's street-view condition.
- A backyard, deck, porch or balcony: does not qualify, however much fencing or privacy the yard has.
- A friend's apartment or a weekend place: the allowance is tied to the primary residence of each adult 21 or older who grows, so plants grown somewhere else are outside the rule.
Keeping plants out of reach of anyone under 21
DCP says home grown plants must be in the primary residence where individuals under 21 cannot access them. So if someone under 21 lives in the home or visits it, the plants need to be somewhere that person cannot get to.
In a home with younger family members, this is the condition that decides the location. A room can pass the indoor and street-view tests and still fail this one if anyone can walk in.
