Quick read: 18-25% THC, 60-120cm mature height, 9-11 weeks total bloom. Genetics: OG Kush F4 IBL (Seedsman genetics). Difficulty: easy.

Lineage: OG Kush F4 IBL traces back through four generations of inbreeding to stabilize one of North America's most recognizable indica profiles — that sharp diesel-and-damp-earth smell is locked in tight here. Seedsman pushed this into autoflower territory without softening the THC ceiling, which still tests between 18–25% depending on how well you dial in the last two weeks of feed.

The full run wraps in 9–11 weeks from seed, and indoor growers pulling 300–450 g/m² put this squarely in the productive range for a plant that doesn't ask much. It handles both indoor and outdoor setups, making it a workable option for Canadian growers trying to squeeze a late-season outdoor run before temperatures drop below 15°C. Difficulty is rated easy, so you're not babysitting it — but don't skip the cure if you want that classic OG nose to fully open up.

Best suited for growers who want a familiar, no-fuss indica without a long photoperiod commitment.

Growing OG Kush F4 IBL Auto

OG Kush F4 IBL Auto 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 9-11 weeks total with yields of 300-450g/m². Plants typically reach 60-120cm 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

OG Kush F4 IBL Auto 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, OG Kush F4 IBL Auto is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension.
