How we checked these dates
We checked each organizer’s own website on October 29, 2026. We only list dates that the organizer has posted. Events we could not confirm on an organizer site are left out or described without a date. Dates and venues can change, so always check the official site before you buy tickets or book travel. Most industry events are limited to adults 21 and older, and some are trade only.

| Event | City | Dates | Who can attend |
|---|---|---|---|

MJBizCon, Las Vegas
MJBizCon is the largest cannabis business trade show in the US. The organizer lists the 2026 edition for December 1 to 4 at the Las Vegas Convention Center, with the main expo floor open December 2 to 4. It is built for business owners, cultivators, investors and service providers, with hundreds of exhibitors covering lighting, cultivation equipment, packaging, testing and compliance. Home growers who work in the industry or are thinking about it often find the cultivation tech and education sessions useful. Register early, since hotels near the convention center fill quickly.
Hall of Flowers, Sacramento
Hall of Flowers is a trade show focused on licensed brands, buyers and retailers. The organizer lists a Sacramento edition for November 4 to 5, 2026. It is known for a curated, design forward feel. It is aimed at the industry rather than the general public, so check the organizer’s attendance rules before planning a visit.
CHAMPS Trade Show, Fort Lauderdale
CHAMPS is a long running trade show for smoke shop, glass and accessory retailers. The organizer lists a Fort Lauderdale edition for November 17 to 19, 2026. It is a business to business event for buyers who are 21 and older. Growers interested in accessories, storage and glass may find it interesting if they have trade credentials.
Cannabis cups in late 2026
Cannabis cups are judging events where licensed producers enter flower and other products and judges or the public rate them. They tend to run during or after harvest season, which is why so many land in the fall and early winter. The High Times Cup has run state editions in legal markets for years, and regional cups in states such as Massachusetts, Arizona and Oregon have built loyal followings. We did not confirm late 2026 dates for these cups on organizer sites, so check each official site for current schedules. Rules on who can judge and attend vary by state, and all require attendees to be 21 and older.
The Emerald Cup in Northern California has been one of the most famous harvest season competitions since it started in 2003. It has moved venues and dates over the years, and we did not find a confirmed December 2026 date when we checked. Watch the official site for news.
Legal seminars and education events
Not every event is a party or a trade floor. The NORML Key West Legal Seminar is a long running continuing education event for attorneys working on cannabis law. Many state cannabis associations and advocacy groups also hold year end policy briefings and member meetings. With federal changes on the calendar, including the change to the federal hemp definition scheduled for December 11, 2026, these sessions may be especially busy this year.
Getting the most out of a trade show
Big shows like MJBizCon can be overwhelming. A little planning goes a long way.
- Pick your goals. Decide whether you are there to learn, to buy, to network or to scout new gear, and plan your days around that.
- Map the floor. Most organizers publish an exhibitor list and floor map ahead of time. Mark the booths you want to see.
- Choose sessions early. Popular education sessions can fill up. Register for the ones that matter to you.
- Bring business cards and a notebook. Write down names, prices and follow up notes right after each conversation.
- Wear comfortable shoes. Convention halls are huge, and you will walk a lot.
- Follow up within a week. Send a short email to the people you met while the conversation is still fresh.
Tips for attending end of year events
- Confirm dates, venues and ticket rules on the official organizer site
- Bring a valid ID showing you are 21 or older
- Check whether the event is open to the public or trade only
- Book refundable travel where possible
- Learn the local consumption rules, which can differ from state possession rules
- Never carry cannabis across state lines or through airports
- Plan a safe way home and never drive after consuming
Planning a winter grow
For many home growers, the end of the year means moving indoors. Shorter days and cold nights end the outdoor season in much of the US, but a grow tent lets you keep going through winter where home growing is legal. Autoflowers are a common winter choice because they finish on their own schedule and stay compact. Photoperiod strains give more control over plant size if you have the space and time. Browse our most popular seeds, autoflower seeds and beginner seeds for ideas. New growers can start with our ultimate beginners guide to growing cannabis and our guide on how to germinate cannabis seeds.
Gift ideas from the events season
Trade shows and cups are a great place to spot new grow tools, storage gear and books. If you are shopping for a grower this holiday season, see our guides to gifts for growers and stocking stuffers. Seeds can make a thoughtful gift for an adult who lives where home growing is legal.
