Strain Description:

Midnight Marathon is a heavyweight OG autoflower built for extreme resin output and knockout effects. Around half of the plants develop dramatic Midnight Purple coloration that contrasts sharply against thick trichome coverage, while the flowers remain dense, sticky and heavily saturated in resin, making them highly suitable for concentrates. Effects strike hard with an initial cerebral lift before rapidly descending into full-body sedation that can lead to couch-lock at higher doses, making it best reserved for evening sessions, stress relief and preparation for deep sleep.


Growing Information:

This sturdy, medium-sized autoflower performs well indoors and outdoors, producing strong lateral branches and tightly packed buds. Low-stress training can improve light penetration and maximise yields, while cooler night temperatures may help encourage deeper purple coloration in many phenotypes. Careful humidity control and airflow are recommended due to dense flower structure, and carbon filtration is advised for indoor gardens because of the cultivar’s extremely pungent OG gas aroma.


Flavour and Aromas:

The profile is dominated by thick, fuel-heavy gas layered over earthy musk and classic kush depth, finishing with a spicy, peppered edge on the exhale. Each draw reinforces its traditional OG character, delivering a bold and lingering sensory experience that fans of old-school fuel-forward strains will immediately recognise.


Strain Lineage:

The Midnight Purple phenotype of Marathon OG Auto F3 contributes dramatic coloration and amplified sedative qualities, while the Marathon OG Auto F3 reversal was selected for intense resin production, powerful gas aroma and vigorous growth. Together they form a visually striking, extract-ready autoflower with uncompromising OG potency.


Effects:

Onset begins with a brief cerebral uplift before rapidly transitioning into dominant physical heaviness and deep relaxation. The body-focused sedation can become overwhelming at higher intake levels, encouraging immobility and sleep, which firmly positions Midnight Marathon as a nighttime-only cultivar for experienced consumers seeking maximum calm and relief.


Strain Summary:

Midnight Marathon by Night Owl Seeds and Dark Owl Seeds is a top-tier OG autoflower defined by extreme resin production, frequent purple expression and crushing sedative effects. Heavy fuel aromas, earthy kush depth and extract-grade frost combine with reliable structure and a 75–85 day finish, making it a prized option for collectors, concentrate artists and lovers of unapologetically powerful nighttime genetics.
