Description

Cultivar profile

Jack Frost is a documented hybrid cultivar associated with a THC range of 18–22%. Its recorded profile also lists CBD at 0%. These figures describe the supplied cultivar entry and should not be assumed to apply to every cultivar or seed line carrying the same or a similar name.

The name Jack Frost identifies this particular catalogue profile. Cultivar names can be reused or applied differently, so lineage and seed-type details are important when distinguishing one entry from another.

Explore feminised seeds, high thc seeds, the Australian grow guide, and the planting calendar.

Genetics and seed type

The documented lineage is White Widow x Jack Herer. Jack Frost is described as a hybrid, reflecting the reported phenotype rather than implying that all similarly named cultivars share the same background.

This entry is for feminised seed. Feminised describes the seed category and is separate from the cultivar’s lineage, aroma and cannabinoid profile.

Aroma and characteristics

The recorded flavour and aroma descriptors are:

  • Citrus
  • Earthy
  • Pine

These are broad sensory terms used to summarise the cultivar’s reported aromatic character. Individual perceptions of citrus, earthy and pine notes may differ, and the descriptors do not establish the identity of other cultivars called Jack Frost.
