About Jack's Critical Autoflower Feminized Cannabis Seeds
Jack's Critical Autoflower Feminized Cannabis Seeds are a blend of Jack Herer, Critical Mass, and Ruderalis genetics. These seeds are autoflowering and feminized, meaning the plants will flower automatically without a change in light cycle and will predominantly produce female plants.
The flowering time ranges from 60 to 70 days, making them a relatively quick option for home growers. The seeds are shipped from Quebec, Canada, and come with a germination guarantee.
Characteristics and Description
While specific aroma and taste profiles are not listed, autoflower seeds like Jack's Critical typically produce plants with a mix of heritage traits from their parent strains. The presence of Ruderalis often contributes to a more resilient plant structure.
The 20% THC level suggests a potent effect, though the exact sensory experience can vary depending on growing conditions and phenotype expression.
Cultivation and Usage Details
These seeds are designed for home cultivation and are suitable for growers seeking autoflowering plants that do not require a shift in light schedule to flower. The flowering period of 60 to 70 days allows for a relatively fast harvest.
Home growers should consider local climate and provincial regulations regarding cannabis cultivation. Seeds should be stored in a cool, dark, and dry place to maintain viability.
Considerations When Ordering Online in Canada
Before purchasing Jack's Critical Autoflower Feminized Cannabis Seeds online, check the available formats and verify the germination guarantee offered by the seller. Prices and seed quantities may vary between online shops.
Be aware of your province's rules on growing cannabis from seeds, as regulations differ across Canada. Also, ensure you meet the legal age requirement for purchasing cannabis seeds.
