Maryland legalized adult use cannabis through a 2022 ballot vote, and sales began in July 2023. The law allows home growing, but the plant cap is one of the smallest in the country. If you plan to grow in Maryland in 2027, you will be working with two plants per household. This guide explains the limits, the rules on where plants can be and how growers make the most of a small count. It is general information for adults 21 and older, not legal advice.

Two plants per household

Adults 21 and older may grow up to two cannabis plants at home. The cap is per household, not per adult, so a house with three adults still has a two plant limit. Every plant counts, including seedlings and clones.

Medical patients

Registered medical patients may grow a larger number, and the household limit for patients is higher. The patient rules have their own details, including age and registration requirements. If you are a patient, confirm the current count with the Maryland Cannabis Administration before you plant.

Where plants can be grown

Plants must be grown at the residence, out of public view and in a way that limits access by anyone under 21. A locked tent, closet or room is the simplest way to meet the standard. Outdoor plants should be behind a fence or wall and not visible from the street, sidewalk or a neighbor’s yard.

Possession limits

Product	Limit for adults 21+
Flower	1.5 ounces
Concentrate	12 grams
Infused products	750 mg THC

Cannabis harvested from your home plants and kept at your home is treated differently from what you carry in public. Keep any harvest above the public limit in a locked container at home. Do not carry large amounts outside.

Gifting and selling

Adults may give cannabis to other adults 21 and older within the personal limits without payment. Selling home grown cannabis, seeds or clones is illegal without a license. So is trading cannabis for goods or services.

Renters, condos and HOAs

Landlords and condo associations may ban cultivation and smoking on their property. Many Baltimore and suburban leases include cannabis clauses. Get permission in writing.

Making two plants count

Two plants can still produce a solid harvest if you plan well:

• Grow larger plants. With a fixed count, plant size matters more than numbers. Longer vegetative growth fills the space.
• Train the canopy. low stress training spreads branches so more bud sites get light.
• Pick reliable genetics. Feminized seeds avoid wasting one of your two spots on a male plant.
• Manage Maryland humidity. Summers are humid, and late season rain raises mold risk outdoors. Choose mold resistant cannabis strains and check buds often in September.

Indoors, a 3×3 or 4×4 tent fits two plants well. Our complete grow tent setup guide covers fans and filters.

Odor and neighbors in dense housing

Row houses and apartments share walls and ventilation. A carbon filter on an indoor tent handles most odor. Drying two plants also releases smell, so plan where they will hang.

What to watch in 2027

Maryland lawmakers have adjusted the cannabis law several times since 2023, mostly on licensing, taxes and enforcement. Bills to raise the home grow cap have been discussed. Watch the 2027 session, which runs from January to April, and check the Maryland Cannabis Administration before you plant.

How Maryland compares with nearby states

Maryland’s two plant cap is small next to its neighbors. Virginia allows four plants per household with tags. Delaware and Pennsylvania do not allow adult home grow. Washington, D.C. allows a small home grow under its own rules. If you move across these borders, the plant rules change completely. Never carry plants across state lines.

A season plan for two plants

• March. Germinate two feminized seeds indoors, with one backup seed only if you plan to discard it before it counts as a third plant.
• May. Move outdoors after frost risk passes, or keep indoors in a tent.
• June to August. Train branches outward and keep foliage thin for airflow.
• September. Inspect buds every few days for mold after humid stretches.
• October. Harvest, then dry in a dark room with steady airflow.

A backup seedling still counts, so remove it as soon as you know both main plants are healthy.

Maryland climate from the mountains to the shore

Maryland packs several climates into a small state. Garrett and Allegany counties in Western Maryland have cool nights and a short season, with frost possible well into May. The Baltimore and Washington suburbs sit in a milder band, while the Eastern Shore is flat, humid and prone to heavy dew in late summer. Those muggy Chesapeake nights are hard on dense buds, so spacing, pruning for airflow and a harvest before October rains matter more than squeezing out extra weeks.

Pests follow the humidity. Caterpillars and stink bugs are common in late summer across central and southern Maryland, and powdery mildew shows up when nights cool. Check leaves and buds every few days during flower. With only two plants, losing one to rot or worms cuts your harvest in half, so prevention is worth the effort. On the Eastern Shore, plant on raised beds, because sandy coastal soils flood after summer storms and the clay soils of the Piedmont drain slowly.

Grow legally and responsibly

Home cultivation is only legal in some states, and each state sets its own plant limits, locking rules and rules about whether plants can be visible from a public place. You must be 21 or older to buy seeds from Kind Seed Co, and you should grow only where your state and city allow it. Check your state rules in our guide to the legal requirements for growing weed plants in your state before you plant. Federal treatment of cannabis seeds is also changing, so read our December 11 2026 seed rule explainer before you order. Keep plants and harvested flower locked away from children, pets and visitors, and never drive after using cannabis. This article is general information about gardening.
