Is it legal to grow cannabis in Missouri?

As of October 2026, adult-use cannabis is legal in Missouri under a measure approved by voters in 2022. Adults may grow at home only if they hold a state cultivation card, which must be renewed every year. Each cardholder may keep 6 flowering plants, 6 non-flowering plants at least 14 inches tall and 6 plants under 14 inches, with a maximum of 12 of each per residence. Plants must be in an enclosed, locked facility and not visible to the unaided eye. Medical patients may also grow under the same plant counts.

Buying cannabis seeds online in Missouri: the federal rules

Under the federal law in force today (the 2018 Farm Bill), cannabis seeds with no more than 0.3% delta-9 THC have been treated as hemp, as the DEA said in informal letters in 2022. A new federal hemp definition takes effect on December 11, 2026, unless Congress delays it again, and it excludes viable seeds from plants above 0.3% total THC. Regulators have not yet said how they will apply it to seeds. Once a seed germinates, state law decides whether you may grow it. Read the federal section of our US guide.

Growing season and climate in Missouri

Missouri has a long, hot growing season, with frost generally arriving in mid-to-late October and later in the Bootheel in the far southeast. Summers are humid and often top 90°F, and dry spells in July and August can stress plants that are not watered regularly. The Ozark hills in the south are rocky and drain quickly, while the northern plains have deeper soils but more exposure to wind and early cold snaps. Spring and fall storms, including hail, are common across the state.

Missouri's long season lets October finishers like Quebec Super Skunk and the mold-tolerant Quebec Cookies ripen fully, while Super Critical is a safer choice for northern counties where cold can come earlier.

  • Quebec Super Skunk – bred by QCS, mostly indica, up to 20% THC, ready in October outdoors
  • Quebec Cookies – bred by QCS, 70% sativa, 19–25% THC, ready late October outdoors, tolerant of common pests and mold
  • Super Critical – bred by QCS, 60% indica, ready late September to early October outdoors

Harvest dates and THC figures are ranges from our strain pages, not promises: results depend on the grower, the method and the season’s weather.
