About Arjan's Ultra Haze

Arjan's Ultra Haze is a Sativa-dominant strain from Greenhouse Seed Co, created by crossing Neville's Haze with Cambodian and Lao genetics. Known for its extended flowering time and strong THC classification, this variety is aimed at growers who appreciate classic long-flowering Sativa traits. These cannabis seeds are intended for collectors and cultivators in regions where cultivation is legal.

As a strain developed from multiple Haze and South-East Asian influences, Arjan's Ultra Haze typically shows an open, airy structure and a long maturation window. Offered here as feminized seeds, it is generally selected by growers looking for plants that can express tall growth and a gradual, progressive flowering phase.

Key details

  • Strain name: Arjan's Ultra Haze
  • Breeder: Greenhouse Seed Co
  • Genetics: Neville's Haze crossed with Cambodian and Lao
  • Type: Sativa-dominant, feminized
  • Flowering time: around 12 weeks in typical indoor conditions

Growing notes

  • Plants often develop a tall, elongated structure, so height management and training techniques are usually recommended.
  • The 12-week flowering period typically suits experienced growers who can maintain stable conditions over a longer cycle.
  • Support for branches may be useful later in flowering, as Sativa varieties can produce long, slender colas.
  • These seeds are generally cultivated indoors or in greenhouses in cooler regions, while warmer climates may allow outdoor growing where permitted.

What to expect

Growers can usually expect a classic long-flowering Sativa profile, with plants that take time to mature but can reward careful management. The strong THC indication suggests effects that are typically potent, in line with many Haze-influenced varieties, though individual experiences and results may vary. As with all cannabis seeds, outcomes depend on environment, grower skill, and local regulations.
