Scotts Miracle-Gro tests its product’s effect on pot

Scotts Miracle-Gro Co. is betting its fertilizer can help cultivate a different kind of grass.

Hawthorne Gardening Co., a subsidiary of the Marysville, Ohio-based company best known for its garden products, has teamed up with Canadian pot producer Flowr Corp. to build a 50,000-squarefoot research facility in British Columbia. The lab will initially be used to test Hawthorne’s lights and nutrients on cannabis, but it hopes to eventually study pot genetics and its impact on human physiology.

“Pretty quickly we realized that cannabis and hydroponics were a big opportunity,” said Chris Hagedorn, general manager of Hawthorne and the son of Scotts Chief Executive Officer Jim Hagedorn. “It has become more acceptable to our investor base, to our board, to our management team and the motivation is obvious: it’s a high-growth category.”

Scotts joins a growing list of large companies testing the marijuana waters. Constellation Brands announced the biggest investment in the sector to date last week, paying $3.8 billion for a 38 percent stake in Canada’s Canopy Growth Corp. Molson Coors Brewing Co. and Heineken have also made initial forays.

Global consumer spending on pot may reach $32 billion by 2022, according to U.S. research firms Arcview Market Research and BDS Analytics. Canada is gearing up to become the first G-7 country to legalize the drug for recreational use on Oct. 17 and its use is spreading around the world.

U.S. federal law prevents Port Washington, N.Y.based Hawthorne from touching the marijuana plant so it’s been testing its cannabis-cultivation products on proxy crops like tomatoes and flowers. Still, the company generates about 90 percent of its sales from the cannabis industry, not including its AeroGrow indoor-gardening business.

“We’re forced to go through this flawed process, selling products without testing them on the actual crops,” Hagedorn said. “Cannabis is such a complex and poorly understood plant at this phase of its evolution that it doesn’t seem super satisfying to test it on petunias.”

Scotts shares have lost about 30 percent this year, including a 14 percent drop on Jan. 30 after it cut its sales forecast, citing a slow start to California’s newly legal recreational pot market and its impact on demand for cultivation supplies.

For Scotts and Hawthorne, a presence in cannabis helps to offset the seasonality of their traditional gardening business.

“It’s a lot of things that Scotts’ core business isn’t: It’s West Coast, it’s younger, it’s male, it’s non-seasonal,” Hagedorn said. “Having a counterpoint to all of those things was really appealing to us.”
