Solid outdoor growing potential with appropriate strain selection.
Michigan has a variable climate with lake-effect weather. The Upper Peninsula has shorter seasons. Indoor growing is popular due to the long winters, but outdoor grows can succeed with autoflowers or fast-finishing photoperiods. The 12-plant limit gives plenty of room for larger indoor setups.
Recommended Strains for Michigan
These strains are particularly well-suited for growing in Michigan's climate.
