Third Thursday and Highest Standards are taking over The Delancey Rooftop for the official Hall of Flowers afterparty on Thursday, October 22. The five-hour New York gathering runs from 5:00 PM to 10:00 PM and gives Hall of Flowers attendees a nearby place to keep the conversation going after the show. The venue is about a 15-minute walk from Pier 36, making it a straightforward plan for people coming directly from the event floor.
What the night is for
This is an industry-facing afterparty rather than another trade-show panel. The hosts describe it as a room for cannabis-industry professionals, executive leadership, store and brand owners, general managers, purchasing managers and budtenders. Third Thursday and Highest Standards are presenting the event, with Honeysuckle and Vertical Supply Co. named as experience partners. Surfside and Sweed appear as showcase partners on the event materials.
Guests with a Hall of Flowers ticket can RSVP through Eventbrite at no additional charge. The flyer says food and an open bar are part of the night, but that does not turn the event into an all-inclusive ticket: arrive with a valid ID and follow the host’s current door and beverage policy. The event is a private 21+ gathering, and the hosts state that IDs and Eventbrite tickets will be checked at entry.
Location and arrival
The Delancey Rooftop is at 168 Delancey Street in New York, New York 10002. Plan to arrive after 5:00 PM and have your Hall of Flowers ticket and Eventbrite RSVP ready before you reach the door. The organizer’s listing describes the event as in-person and lists a five-hour run time. Any RSVP availability, entry procedure or partner programming can change, so check the Eventbrite page immediately before travel instead of relying on a screenshot or an earlier social post.
Who should go
The draw is the room. Hall of Flowers brings together the people who make purchasing, retail, brand and culture decisions; this afterparty is built for conversations that do not fit into a booth appointment. If you are a retailer, operator, buyer, brand owner or working professional with a Hall of Flowers ticket, it is an accessible way to meet the broader New York cannabis community in a less formal setting.
It also has enough crossover appeal for people who work around the industry’s culture layer. Highest Standards, Third Thursday, Honeysuckle, Vertical Supply Co., Surfside and Sweed give the event a mix of community, media, supply and retail perspectives. Expect a social setting anchored in music, food, drinks and introductions rather than a curated speaker schedule. Go in with an open calendar, a charged phone for your Eventbrite confirmation and a plan to walk over from Pier 36 if you are attending Hall of Flowers that day.
The official Hall of Flowers afterparty is a one-night New York stop with clear timing, a known venue and a defined attendee pathway. RSVP first, bring the required ticket and ID, and treat the published 5:00 PM–10:00 PM window as the time to make the most of the room.
