Strain Description:

Arjan’s Ultra Haze #1 embodies the essence of classic Southeast Asian sativa genetics. Expect tall, elegant plants with long internodes and a naturally spreading structure perfect for training. The flowering process is slow and steady, but ultimately produces large, resinous colas infused with a rich aromatic profile. Its high is mellow, cerebral, and introspective, developing gradually into a meditative mental state rather than delivering a sharp or racy buzz. This makes it ideal for thoughtful, quiet moments and extended creative flow.


Growing Information:

Due to its long flowering time and height, this strain is best suited to experienced growers. Indoors, it thrives when trained—SCROG, LST, and canopy control techniques help manage stretch and maximise light exposure. Outdoors, it performs best in warm, tropical, or temperate regions where its long season can fully develop. Patience is rewarded with exceptional yields that reflect its vigorous sativa heritage.


Flavour and Aromas:

The profile combines earthy herbal tones with subtle tropical spice from its landrace roots. On the palate, smooth woody notes blend with floral sweetness and a gentle spicy finish. These layered flavours complement its calming, reflective high and make for a soothing, aromatic experience.
