Strain Description:
Arjan’s Ultra Haze #1 is a highly sativa-dominant hybrid developed from the cross of Neville’s Haze and two Southeast Asian landraces from Cambodia and Laos. This unique lineage results in a long-flowering plant with elegant, elongated branches and large internodes, ideal for training techniques such as LST (low-stress training). Its effect is a slow-building cerebral experience, perfect for quiet reflection or meditation, rather than an intense buzz. The flowers develop slowly but mature into large, resinous colas with a rich terpene profile.

Outdoors, Arjan’s Ultra Haze #1 thrives in tropical to temperate climates and can produce up to 1150 g per plant by early November.
