Permanent Marker – New 2026

The Permanent Marker Strain: High-THC Cookies Power

Permanent Marker feminized cannabis seeds combine Biscotti, Sherbert BX1, and Jealousy into a 70% indica-dominant powerhouse with standout potency and heavy flavour. Our breeders selected this line for dense resin production, a loud candy-diesel nose, and dependable photoperiod performance from veg to harvest.

Permanent Marker Strain: The Offspring of Biscotti x Sherbert BX1 & Jealousy

Permanent Marker started with a pairing of Biscotti and Sherbert BX1, before that standout selection was crossed with Jealousy. Biscotti brings dessert-like sweetness and a dense, indica-leaning structure, while Sherbert BX1 adds creamy candy notes and the potential for colourful fades. Jealousy rounds everything off with modern Cookies-family punch, extra resin, and a layered terpene profile that really shines after a proper cure.

Effects and Flavours of the Permanent Marker Strain

This cultivar leads with candy sweetness on the inhale, followed by herbal depth, cracked pepper, and a lingering diesel edge. Break apart cured buds, and the aroma sharpens, with fuel and spice pushing through the sweeter top notes.

In terms of effects, Permanent Marker is known for a bright, euphoric lift at the start that can feel creative and upbeat, before the indica weight becomes more pronounced. With THC levels reaching around 28%, this is a long-lasting, heavy-hitting experience, made more nuanced by a terpene profile that goes beyond a simple ?stoned? finish.

Growing Characteristics of Permanent Marker Cannabis Seeds

Permanent Marker stays manageable indoors, typically reaching 80?120 cm and producing around 500?550 g/m? under strong lighting. Outdoors, plants can stretch to 140?180 cm and yield roughly 550?600 g/plant, with harvest time arriving in October in suitable climates.

Flowering takes 8?10 weeks, giving growers a practical window to dial in ripeness, resin, and aroma. Because buds pack on serious density, consistent airflow through late bloom is a must to help manage moisture. Light training and moderate defoliation can also improve canopy penetration and support more even development across lower bud sites.
