Quick read: 17-22% THC, 80-150 cm mature height, 8-10 weeks bloom. Genetics: Fire OG Feminized (Seed Supreme genetics). Difficulty: moderate.

Lineage: OG Kush × SFV OG Kush, two of the more respected California indica lines — and the cross shows up clearly in both the nose and the numbers. Fire OG Feminized tests between 17–22% THC, with a dense, resinous structure that leans heavily on its OG roots. The scent profile stays true: earthy soil and fresh pine, nothing tropical or candy-sweet, just the classic damp-forest funk that OG fans recognize immediately.

Indoors, expect 400–550 g/m² after an 8–10 week flower period, which fits comfortably within most Canadian indoor schedules. The plants respond well to moderate feeding but can be finicky about humidity during late flower — keep it under 45% RH once buds start stacking to avoid moisture issues. Difficulty is rated moderate, so newer growers can manage it, though some LST or light defoliation will help canopy airflow.

Best suited to growers who want a reliable, resin-heavy OG-style producer without chasing novelty genetics.

Genetics & Lineage

Fire OG traces its genetics to Fire OG Feminized (Seed Supreme genetics). This indica-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 Seed Supreme, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and sleepy 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 22%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Fire OG delivers THC levels of 17-22%, 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 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing Fire OG

Fire OG 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 400-550 g/m². Plants typically reach 80-150 cm 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 40-50% 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

Fire OG features a earthy, pine terpene profile that develops complexity throughout the flowering cycle. Sharp forest and resin notes create a fresh, invigorating flavor with earthy depth. 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, Fire OG 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 Fire OG?

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.
