Why this one matters: hybrid genetics with a 20-25% THC ceiling and fruity/citrus-led terps. 8-10 weeks flowering, indoor or outdoor.

Smell-first impression on Permanent Marker: citrus peel and ripe stone fruit hit before you even break a bud open, with a sweet finish that sits clean rather than cloying. Blimburn bred this one to land between 20–25% THC, which puts it firmly in the upper-mid range — noticeable without being a one-and-done experience. Effects tend toward relaxed and creative, useful for evening wind-downs or low-key studio sessions.

On the grow side, expect 8–10 weeks of flowering and a canopy that responds well to moderate training. Indoors or out both work here, though indoor growers running tight environments will appreciate the 400–500 g/m² return without having to push nutrients hard. Difficulty sits at moderate — you'll want some experience reading plant stress, but nothing about this strain punishes honest mistakes. Good pick for a grower who's moved past their first couple of harvests and wants a reliable fruity cultivar that earns shelf space.

Genetics & Lineage

Permanent Marker traces its genetics to Permanent Marker (Blimburn Seeds). This hybrid-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Blimburn Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Permanent Marker delivers THC levels of 20-25%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes with a balanced head-and-body experience that evolves over time.

Growing Permanent Marker

Permanent Marker is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

Permanent Marker features a fruity, citrus, sweet, pine terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Permanent Marker is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.

Who Should Grow Permanent Marker?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
