Can I Legally Grow Weed at Home? State-by-State Guide Right Here

Matt Weeks October 2, 2020 0 comments

This is a state-by-state guide to current home grow laws in America.

There’s no one answer to the question, “Can I grow weed at home?” in the United States. The patchwork of laws changes from state to state, leaving home horticulturists to hunt for answers — until now. Only states that have given residents the right to grow cannabis are included in this guide. Some states have implemented medical cannabis programs without extending home growing rights – and are thus not included. Each entry has links to official state programs that go into further detail.

So whether you have one small space utilizing grow lights or a large outdoor area with good quality soil to work with, this is the best place to start to answer the question “Can I grow weed at home?”


As a state with legalized recreational cannabis, the biggest state allows people age twenty-one and older to grow cannabis — with certain restrictions.

Alaska allows each person to grow six plants at a time, but forbids more than twelve plants growing in any one household.

Here’s the tricky part: Only three plants can be mature or flowering at any one time. For multiple grower residences, that number is six.


Medical cannabis patients or their caregivers may grow cannabis for individual, medical consumption in Arizona.

That’s the good news. The bad news is that growers must live at least twenty-five miles away from the nearest medical cannabis dispensary, obtain a license from the state (for a fee, naturally), and cultivate their plants in an enclosed and lock area that is not readily visible to the public.

The state also limits the number of plants that can be cultivated at each home grow operation to six.

Sweet-soiled California allows anyone older than twenty-one to grow up to six cannabis plants for recreational use on the condition that it not be sold.

The state also allows any medical cannabis patient or caregivers to dedicate one hundred square feet toward growing medical cannabis for individual consumption. There is no limit on the number of cannabis plants you can grow within the one hundred square feet.

However, there are restrictions. People can’t grow plants in areas that are visible from the street or public walkway. It cannot be grown inside a residential structure, and must be confined to an additional building, such as a shed or greenhouse.
