Permanent Marker XL Auto | Sweet Seeds

Permanent Marker XL Auto® by Sweet Seeds® – An XL Autoflower with 23–30% THC

Permanent Marker XL Auto® brings the raw intensity of modern Californian genetics into a fast, high-yielding XL autoflower format. Created by crossing Permanent Marker with Permanent Jealousy XL Auto®, this 8th-generation autoflower delivers extreme potency, heavy resin production, and a bold, complex terpene profile.

 

With THC levels ranging from 23% to 30%, it stands among the strongest autoflower cannabis seeds in the Sweet Seeds® lineup. From seed to harvest in just 8–9 weeks, it combines speed with true Cali-style power.

 

Genetics & Plant Structure – Cali Power in Autoflower Form

This strain features 66.6% indica, 33.3% sativa, and only 0.1% Ruderalis genetics. The result is a vigorous plant with a medium-to-tall profile and an open structure that supports strong airflow and consistent light penetration.

 

Plants typically reach between 50–130 cm, making them adaptable to indoor grow tents while still performing strongly outdoors. Thick, compact, and heavily resin-coated buds develop along sturdy lateral branches.

Heavy Resin Production – Built for Extractions

Permanent Marker XL Auto® produces thick, dense buds completely coated in large, glistening trichomes. This exceptional resin output makes it an excellent choice for solventless and solvent-based extractions.

 

Its terpene intensity translates beautifully into concentrates, preserving its sweet, Cookies-inspired complexity.

 

Flavor & Terpenes – Candy, Gummy, Cookies & Diesel

The terpene profile is bold and unmistakably modern. Sweet candy and gummy notes dominate the aroma, layered with classic Cookies-family nuances and subtle mint undertones.

 

An earthy base with Skunky depth and light Diesel accents adds structure and complexity. On the inhale, expect sweet creamy tones with a fresh, slightly mentholated finish.

 

Effects – Creative Lift with Relaxed Depth

The effects begin with a clear, uplifting cerebral rush.

 

Creativity flows easily, mood elevates, and focus sharpens before transitioning into a pleasant body relaxation. Despite its high THC level, the experience remains balanced rather than overwhelming, making it ideal for evening wind-down sessions without full sedation.
