ILGM runs this as a indica feminized line — 21-25% THC lab range, diesel/earthy-dominant terps, 8-10 weeks from flip.

Lineage: OG Kush × SFV OG Kush — Fire OG sits at the heavier end of the OG family, testing consistently between 21–25% THC with a CBD reading that barely registers. The nose leans hard into diesel with a damp-earth base underneath, and that profile carries right through to the smoke. Indoors it finishes in 8–10 weeks and can push 350–500 g/m² under decent light without demanding much from the grower — difficulty is rated easy, and these feminized seeds handle both indoor and outdoor runs without complaint. Outdoor growers in warmer Canadian zones (think southern Ontario or the BC interior) can run this successfully, though you'll want to harvest before overnight temps drop below 10°C consistently.

These feminized seeds suit growers who want a straightforward, high-THC indica without babysitting a difficult cultivar through flower.

Genetics & Lineage

Fire OG traces its genetics to Fire OG (ILGM 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 ILGM, 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 25%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Fire OG delivers THC levels of 21-25%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. 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 easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 350-500g/m2. Plants typically reach 90-160cm 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 diesel, earthy terpene profile that develops complexity throughout the flowering cycle. Pungent fuel and chemical notes hit first, followed by an earthy, musky undertone. 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 beginner growers looking for a reliable, low-maintenance plant that delivers consistent results without advanced techniques. If you're looking for evening relaxation and deep stress relief, this is your strain.
