Buying cannabis seeds online in Montana: 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 Montana
Montana's frost-free season is short almost everywhere, and in the mountain valleys of the west it is especially brief, with frost possible in early September or even late August. The eastern plains are lower and get more summer heat, but they are windy, dry and exposed to sudden cold fronts. Strong sun at altitude and cool nights produce sturdy plants, though big day-to-night temperature swings slow growth late in the season. Many growers start plants indoors and move them out only after the last spring frost.
With only two mature plants allowed per adult and frost possible by early September, mid-September finishers and a compact autoflower give the best odds of a full harvest at Montana's elevations.
- Quebec Early Bud – bred by QCS, balanced hybrid, about 20% THC, ready mid-September outdoors
- SFV OG Fast Version – mostly indica, about 24% THC, ready mid-September outdoors
- Northern Lights Autoflower – bred by QCS, autoflower, 90% indica, compact, 50–60 days
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.
