GrowGen CEO Comments:

Darren Lampert, CEO, commented, "H2O Hydroponics is the largest hydroponic store in Lansing, MI. with 2019 sales of approximately $4.0 million. We are consolidating our current West Lansing location, with H2O, and relocating  into a newly built 15,000 square foot super hydroponic garden center, that we expect will generate over $7.0 million in sales. With this acquisition, we continue to increase our footprint and strengthened our supply chain in the Michigan market."

Michigan Market:

According to a March 2020 report, "The Market for and Economic Impact of the Adult-use Recreational Marijuana Industry in Michigan" by Michigan State University Product Center Food-Ag-Bio: 

"It is estimated that the level of cannabis retail sales once it becomes widely available is approximately $3 billion with a total economic impact in excess of $7.8 billion. Employment in businesses along the marijuana supply chain is estimated to be 13,500 with a total economic impact on employment in the state of 23,700. Total tax revenue raised is $495.7 million of which $298.6 million is excise taxes and $197.1 million are in the form of sales taxes.
The supply chain for marijuana was also analyzed. It appears that the supply chain is maturing rapidly, with several well-funded vertically integrated firms already operating. Both indoor and outdoor growing operations are in place but over time it appears that much of the production will take place in dedicated indoor growing facilities."

In November 2018, Michigan became the 10^th state to legalize cannabis for adults and the first state to do so in the Midwest. Within a residence, adults may grow up to 12 plants and/or possess up to 10 ounces.  Medical cannabis is permitted. An individual may register as a medical patient if their doctor certifies that the individual suffers from one or more of the qualifying conditions under the state law.
