Lineage: OG Kush F4 IBL, stabilized across four filial generations by Seedsman, meaning the auto version holds onto the original's diesel-and-earth nose without the genetic drift you see in earlier crosses. That consistency shows up in the numbers — 18–25% THC from an autoflower that wraps up seed-to-harvest in 9–11 weeks, which is fast for a strain carrying this much OG character.

Yields sit in the 300–450 g/m² range indoors, reasonable for the cycle length and a footprint that works equally well under LED tents or in an outdoor container run. Difficulty is rated easy, so newer growers won't fight the plant, but the potency skews heavily toward body-dominant effects — worth knowing if you're planning an afternoon session. Best suited to growers who want a classic OG profile in an auto format without babysitting a difficult pheno.

THC Level & Potency

OG Kush F4 IBL Auto delivers THC levels of 18-25%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies.

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. 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.
