Key specifications

Genetics and origin

Purple Urkle emerged in California in the 1980s and is based on Mendocino Purps — one of the best-known purple genetics from the famous Mendocino County in Northern California. This region is renowned for its exceptional indica phenotypes with anthocyanin colouring. For decades, the Purple Urkle strain has been a reference for grape aroma and violet colours. Purple Urkle Pyramid Seeds is the original feminized version of this classic Purple Urkle weed. Part of the American Strains collection and the Rare Cannabis Seeds category.

Purple Urkle effect

The Purple Urkle effect is typical of an 80% indica-dominant phenotype — deep, body-forward and long-lasting:

• Deep muscle relaxation — the classic indica body effect, tension dissolves completely
• Calming and sedating — ideal for the evening and sleep support
• Stress relief — thoughts slow down, inner calm sets in
• Mood lift — a pleasant serenity without intense euphoria

At 20–22% THC the effect is intense but controllable — typical of well-stabilised indica genetics with a long history.

Aroma and terpene profile

The aroma profile of Purple Urkle is unmistakable: sweet ripe grapes as a base, complemented by tropical fruit notes, spicy and earthy accents and a light rain undertone. The grape profile is the hallmark of this line — instantly recognisable and prized by purple lovers worldwide.

Why violet? The science behind the colour

The intense violet colouring of Purple Urkle comes from anthocyanins — plant colour pigments that activate at cooler night temperatures (below 15 °C) in late flowering. Colder nights intensify the violet shades — a simple tool for producing even more spectacular buds. The violet colour is genetically determined, not induced by cultivation tricks.

Growing — indoor and outdoor

Indoor growing

Flowering time 55–60 days (LED: 48–53 days). Yield: 500 g/m² standard, up to 750–800 g/1.5 m² with a 720 W LED. SOG and LST recommended for maximum yield. For more intense violet colouring: lower the night temperature to 15–18 °C in the last 2 weeks of flowering. Keep humidity below 50% in late flowering.

Outdoor growing

Harvest in September in the northern hemisphere. 0.75–1 kg per plant. The natural temperature drop in autumn intensifies the violet tones automatically — a clear advantage for outdoor growers in temperate climates.
