Can I Grow Weed in Germany?
Yes. Since April 1, 2024, adults 18+ in Germany can legally grow up to three cannabis plants per person at home for personal use. Plants must be secured against access by minors and third parties.
Detailed Answer
The Cannabis Act (CanG) that took effect on April 1, 2024 permits every adult resident of Germany aged 18 and over to cultivate up to three flowering cannabis plants simultaneously for personal use. This limit is per person, not per household — so a household with two adults can theoretically grow six plants. Seedlings and non-flowering plants (those in vegetative state) do not count toward the three-plant limit.
Cultivation must take place in the grower's primary residence — either indoors or in an enclosed area of private outdoor space such as a balcony, terrace, or garden that is not freely accessible from public areas. Plants must be secured to prevent access by children and unauthorized persons. Specific measures are not mandated, but a lockable room, a secured garden area, or a grow tent in a private space would generally suffice.
The law does not restrict specific growing methods, equipment, or inputs. Growers may use soil, hydroponics, grow lights, fertilizers, and any cultivation technique they prefer. There are no requirements to register plants or report growing activities to authorities. However, the harvested cannabis is subject to the same possession limits as all recreational cannabis: up to 50 grams of dried flower may be stored at home, and up to 25 grams may be carried in public.
Landlords cannot prohibit cannabis cultivation through lease terms, as the activity is legal under federal law. However, growing operations that cause damage (such as mold or electrical issues), create strong odors detectable in common areas, or violate building safety codes could still constitute lease violations. Renters should be mindful of ventilation, odor control, and electricity usage to maintain good relations with landlords and neighbors.
