A5
Northern Lights #5 × Haze A
A5 is a highly regarded Dutch Haze clone originating in the late 1980s and early 1990s. It is a hybrid that traces its lineage to Nevil Schoenmakers' experimental Haze A male crossed with Northern Lights #5, creating a potent and influential strain.
Appearance
A5 grows tall and vine-like, characteristic of its sativa heritage, with narrow leaflets and long internodes. It exhibits prolific branching and develops elongated, foxtail-shaped buds densely covered in trichomes. While typically green, some phenotypes may show muted purples or bruise-like hues in cooler temperatures.
Aroma & Flavor
The aroma of A5 is predominantly described as "church incense," featuring notes of cedar, frankincense, and peppery spice over dry, herbal wood. Secondary notes can include bay leaf, coriander, old leather, and sometimes a faint citrus peel or metallic edge. The flavor profile mirrors the aroma, offering a complex blend of woody, spicy, and herbal notes.
Effects
A5 is known for delivering a potent, cerebral, and energetic experience that is often described as uplifting. It combines the soaring headspace of classic Haze with a weighty, modern punch, promoting creativity and sustained mental activity. Sensitive users may experience anxiety or dizziness.
Terpenes & Cannabinoids
With THC levels reported around 25% and CBD below 1%, A5 is a high-potency strain. Its terpene profile is characterized by Caryophyllene, Humulene, and Terpinolene, contributing to its distinctive spicy, woody, and peppery aroma and effects.
Origins & Lineage
A5 Haze is a clone-only hybrid developed by Nevil Schoenmakers, stemming from a Northern Lights #5 mother pollinated by the "Haze A" male. It is considered a foundational strain in European cannabis breeding, influencing hybrids like Barney's Farm Tangerine Dream. Its sibling is the C5 line, which utilized the "Haze C" male.
Growing
Cultivating A5 presents challenges due to its tall, stretching growth habit and long flowering time, demanding significant grower attention. Indoor growers must manage its vigorous vertical growth with early training and support structures like trellising. Proper airflow and humidity control are crucial, especially late in bloom, to prevent issues with its resinous, foxtail bud structure.
