Permanent Marker Seeds

Genetics & effects

Permanent Marker is a feminised photoperiod hybrid combining Biscotti, Jealousy and Sherbet genetics. Its profile leans 60% indica and 40% sativa, balancing vigorous growth with dense flower development. THC is listed at 20–34%, while CBD is listed at 0–0.2%, placing this among the more potent options in the feminised seed collection.

The aroma and flavour can bring together floral sweetness, candy, lemon and citrus over pungent, soapy and skunk-like notes. Caryophyllene, limonene and myrcene are the prominent listed terpenes. Individual experiences vary, though some people describe the effects as initially energetic, creative, euphoric or uplifting, followed by a powerful sense of relaxation. Environment, phenotype and personal sensitivity may all shape the experience.

Growing in Australia

Permanent Marker is rated for intermediate growers and may suit hot, dry or temperate Australian climates. Its vigorous structure and potential height benefit from early planning, airflow and regular canopy checks. As a photoperiod cultivar, flowering begins as daylight hours shorten rather than at a fixed age.

For seasonal outdoor cultivation, spring planting falls between September and November. Local conditions differ widely across Australia, so timing should reflect regional temperatures, rainfall and day length. Avoid persistently damp positions and allow generous spacing around plants to reduce the risk of mould in dense flowers.

Indoor

Indoors, plants may reach up to 170 cm and generally flower for eight to ten weeks. Topping, low-stress training or a supported screen can help manage vertical growth and distribute light across the canopy. Strong air exchange is useful as flowers gain weight, while supports may help branches remain upright late in bloom.

• Flowering: approximately 8–10 weeks
• Indoor height: up to 170 cm
• Indoor yield: up to 550 g/m²
• Skill level: intermediate

Stable temperatures, sensible humidity and consistent lighting can support even development. Listed yield figures are estimates rather than promises, with outcomes influenced by phenotype, equipment, environment and grower technique.

Outdoor

Outdoors, Permanent Marker may grow to around 200 cm and can form a broad, productive frame in ample sun. Hot, dry conditions may showcase its resilience, while temperate gardens benefit from a bright position with dependable airflow. Use discreet structural support before flowers become heavy, and monitor changing autumn weather closely.

• Outdoor height: up to 200 cm
• Outdoor yield: up to 850 g per plant
• Preferred climates: hot, dry and temperate

Harvest

Australian outdoor harvest commonly falls from March to May, depending on latitude, planting time, phenotype and seasonal conditions. Assess flower maturity directly rather than relying only on the calendar. After cutting, maintain gentle airflow and stable darkness during drying to preserve the cultivar’s distinctive colour, citrus sweetness and pungent character. Permanent Marker is presented in the Outback Seed Bank catalogue as a bold choice for growers seeking expressive aroma, substantial size and a potent hybrid profile.
