Glass House Hits the Gas on 2026 Expansion, Adds 300,000 Pounds of Capacity

California weed powerhouse Glass House Brands this week announced its 2026 expansion plans, which will increase cultivation capacity by more than 300,000 pounds of cannabis biomass per year. The plans include completing Greenhouse 2 at the vertically integrated cannabis company’s Southern California farm and building out Greenhouse 4, which will eventually produce cannabis for markets outside California.

The work at Greenhouse 2 was one-third completed last year. But a raid at the company’s facilities by federal officials in July, after which one worker died, prompted a temporary halt in construction and scaled-back production. Construction was originally scheduled to resume later this year.

“We are very pleased with and proud of our team’s ramp back efforts of the past six months for existing greenhouses along with early results from Greenhouse 2 expansion,” Kyle Kazan, chairman and CEO of Glass House, said in a statement about the development. “The Company is ready to put its foot fully back on the gas pedal. We anticipate strong growth in 2026 and beyond.”

Kazan cited several reasons for the accelerated expansion, including President Donald Trump’s executive order last month to reschedule cannabis under federal drug laws. At the same time, the administration announced a pilot program covering up to $500 in CBD products per year for seniors enrolled in Medicare.

“We are planning for the associated new business opportunities that we expect to come from cannabis rescheduling and the creation of the new Medicare reimbursement program for CBD,” said Kazan. “We remain confident that Schedule III under the current administration can provide cannabis export opportunities in the near term to Europe and other international markets. The wholesale biomass prices are expected to be meaningfully higher than those achievable in California.”

‘The Best Weed Glass House Has Ever Grown’

Glass House president and co-founder Graham Farrar shared more information about the company’s plans in a phone interview with IgniteIt. Once the 2026 expansion is up and running, he says, “we are going to grow the best weed Glass House has ever grown out of Greenhouse Two.”

The company was originally planning to finish the second two-thirds of Greenhouse 2 later this year, with work commencing in June or July. But early results from the completed section of the facility have led Farrar to reconsider the timing.

“We’re going to do it now, which is going to get us about an extra six months of production, because we really like the results that we’re getting out of the first third that we finished,” he explains. “And we’re back and running with more acres planted now than ever before in Glass House history.”

With the accelerated expansion, the company plans to have Greenhouse 2 finished and fully planted during the second quarter of 2026. In total, Greenhouse 2 will provide an incremental annual production capacity of approximately 300,000 pounds of cannabis biomass.

Glass House also announced that it would begin a light retrofit and buildout of the SoCal farm’s Greenhouse 4, with plans for production capabilities to target international CBD and hemp markets in the UK, EU and Asia.

“Every single one of those markets starts with the plant,” Farrar says, “and what Glass House has better than anyone else is growing that plant, better, at a larger scale, with more consistency and more efficiently than everybody else.”

He added that the company’s expansion plans also support the potential for growth from the federal government’s planned Medicare coverage for CBD.

“That is a $35 billion market right there that was not on our bingo card or on our radar at all,” Farrar says, “and all of a sudden it is.”
