Glass House Farms is the flower brand of Glass House Brands, grown in coastal greenhouses in Carpinteria and Camarillo and sold only through licensed California retail and delivery. Its cultivation license, CCL18-0000512, sits in Carpinteria, and the lineup runs from eighth jars and Farm Packs to pre-roll packs and infused pre-rolls.
It keeps collecting hardware. Glass House Farms took 17 medals in mixed-light flower at the 2026 California State Fair Cannabis Awards, and Peanut Butter Breath won Best Hybrid at Farmers Cup 2026.
Dutch greenhouses in the Carpinteria Valley
The brand leans on local history. Dutch farmers arrived in the Carpinteria Valley in the 1960s and grew flowers under glass because of the climate. Glass House grows cannabis in the same kind of Dutch greenhouse, under high-transmittance glass roofs with high-efficiency temperature control.
Automation tailors light, nutrients, water and ventilation to growing cycles, weather and each strain's preferences. The farm recaptures and recirculates water and runs integrated pest management. Cannabis & Tech Today gave it Sustainable Leadership Awards for stewardship in 2020 and for energy consumption in 2021.
Kazan, Farrar and 6 million square feet of glass
Kyle Kazan and Graham Farrar co-founded Glass House, which dates to 2015. Kazan is chairman and CEO, and Farrar is president and a board member. On the brand's site, Farrar says everything from its community work to the way it cultivates and packages "contributes to our local economy and environment in a positive way."
The company counts about 6 million square feet of greenhouse space, led by the 5.5 million square foot SoCal Greenhouse, plus the Padaro and Casitas farms. Its June 30, 2026 financial statements place cultivation at Camarillo, Padaro and Casitas. Kirk Weatherton, head grower of the Camarillo flower houses, joined in December 2018 with more than 15 years of cultivation behind him.
Eighth jars, Farm Packs and 200-plus strains
The core catalog covers eighth jars, larger Farm Packs, single pre-rolls, pre-roll packs and infused pre-rolls, plus merchandise. Every product is tested by California-licensed labs and carries a state track-and-trace batch number. The brand's lab-results database lists more than 200 strains, searchable by strain, product type or batch.
The 2026 certificates show the rotation. August 27 brought results for GrapeZ, Jelly Fish and Zoap flower, Peanut Butter Breath and Golden State Jack pre-roll packs and a Flash Mob infused pre-roll. July batches covered Lilac Diesel, Cherry AK, Super Boof and MAC 1 pre-roll packs.
June 5, 2026 brought three flower drops: Super Boof, Trop Queen and Infamous MF. On September 16, 2026, the brand's journal introduced Rachel's Rapture, a Gumbo x Gelato hybrid.
Lilac Diesel's Golden Bear and a medal run
Lilac Diesel broke through first. It won the Golden Bear for Best of California in mixed-light flower at the 2024 California State Fair Cannabis Awards, plus gold in Total Terpenes, Ocimene and Terpinolene and silver in CBGa. mg Magazine's July 30, 2024 results release put that field at more than 500 entries.
The 2025 awards added 15 medals, with Cherry AK, Mafia Funeral, Donny Burger #5 and Jelly Fish among the winners. In 2026 the count hit 17: four gold, five silver and eight bronze. Cherry AK took gold in Total Terpenes and Terpinolene, Futura Haze in Ocimene and Infamous MF in Caryophyllene.
Peanut Butter Breath added a bronze in Pinene at the 2026 State Fair, weeks after its Farmers Cup 2026 Best Hybrid win was announced on June 5.
Run clubs and golden tickets
The brand works the scene off the shelf too. Glass House Run Club, introduced on the journal in March 2026, is a monthly 4.20-mile group run in Mid-City Los Angeles with The Pottery, followed by a recovery lounge stocked by PLUS and Mama Sue Wellness. The 21+ runs require Eventbrite registration.
An August 26, 2026 post recapped a 2-mile run with Mr. Charlie's, a plant-based fast-food restaurant in Santa Monica. The April 28, 2026 Golden Ticket post covered loyal customers from Farmacy, NHC and The Pottery, plus standout budtenders, touring the Carpinteria greenhouses. One top customer got to pick a strain and name it before release.
NYSE listing and a retail reshuffle in 2026
Parent Glass House Brands began trading subordinate voting shares on the New York Stock Exchange as GLAS on June 30, 2026, and kept its Cboe Canada listing as GLAS.A.U. Kazan tied the move to the reclassification of medical cannabis to Schedule III.
Retail changed shape the same season. On April 13, 2026, Glass House announced a 50/50 California retail joint venture with Vireo Growth, contributing 11 stores including The Farmacy, NHC and The Pottery, with preferential supply of its products. On June 12, 2026, it deconsolidated its retail business into Glass House Retail, LLC, keeping about a 90% economic interest.
The farms kept scaling. Second-quarter 2026 production hit a record 245,746 equivalent dry pounds at $122 a pound, on 1,708,000 square feet of licensed canopy. Glass House Farms flower still sells only through licensed California retail and delivery, alongside portfolio brands PLUS, Allswell and Mama Sue Wellness.
