Growing Cannabis for Personal Use: US Home Grow Laws
Home grow laws by state: plant limits, age rules, federal status, and where growing cannabis for personal use is still illegal in the US.
Before you buy seeds, clones, or grow equipment, confirm that your state allows home cannabis cultivation. As of 2025, more than 20 states plus the District of Columbia permit some form of home growing for medical or adult use. If your state is not on that list, buying from a licensed online retailer may be your legal option. Always check state and local laws, because rules change and local bans can override state permission.

What to Look For in Home Grow Laws
Home cultivation laws vary by state. Look at four main factors: who can grow (medical patients only vs any adult), how many plants you can keep, how much harvested cannabis you can possess, and where you can grow. Some states cap plant counts at 6 per adult, others allow up to 12 per household. A few states require registration or plant tags. Local ordinances may prohibit outdoor growing or impose distance requirements from schools and parks.
