Description

Extraction OG 18 Kush Strain Info

Extraction OG 18 Kush is a feminized photoperiod strain with a 30% Sativa/70% Indica ratio and 18-22% THC. CBD is listed in the source text as low, around 0.1-0.2%, so the effect stays mostly THC-led. The strain carries a diesel-pine flavor with a strong pungent base, giving it that unmistakable Kush-style personality. Its effects begin with euphoria and a happier mental tone before the Indica side settles into relaxation. In the grow room, Extraction OG 18 Kush reaches about 5.2ft (160cm), making early canopy control useful for indoor cultivators working with limited vertical space.

Genetics

Extraction OG 18 Kush was created by pairing OG Kush with Chemdog. OG Kush brings the deep Indica structure, pine-heavy aroma, and relaxed character that made the family famous. Chemdog adds diesel sharpness and extra punch, helping shape a cultivar with strong resin potential and a flavor profile made for extract-focused growers.

Flowering Time

Extraction OG 18 Kush flowers in 56-63 days. That timing keeps it efficient for an Indica-dominant photoperiod strain, especially when conditions stay warm, bright, and steady through bloom. Low stress during flowering will help the plant keep its rhythm and preserve the pungent aromatic profile that defines this cultivar.

Yields

Indoors, Extraction OG 18 Kush can produce around 1.3-1.8oz/ft² (400-550g/m²). Outdoors, growers can expect approximately 21-28oz (600-800g) per plant in suitable conditions. The yield potential is solid on both sides of the grow tent door, especially when plants receive strong light and stable warmth.

Effects

The high starts with a euphoric lift that gives the mood a softer edge, like turning down the static after a long day. Happiness comes through in a calm, easy way, making the smoke feel friendly without becoming overly stimulating. As the effect deepens, the body relaxes into a heavier Indica groove, better suited for slow evenings than ambitious productivity marathons.

THC and CBD Levels

Extraction OG 18 Kush contains 18-22% THC, which gives it noticeable potency while keeping the experience manageable for many users. CBD is listed at around 0.1-0.2%. This cannabinoid profile supports a clear THC-forward effect, with the low CBD level playing a subtle role rather than shaping the experience directly.

Smell and Taste

The aroma is bold from the start, led by diesel sharpness and grounded by pine. A pungent cannabis note fills the background, giving the buds a loud jar presence that feels classic rather than trendy. On the inhale, the diesel character hits first, while the pine finish leaves the smoke crisp and resinous.

Grow Tips

Extraction OG 18 Kush prefers a warm, sunny climate inspired by its West Coast roots. The ideal temperature range is 70-80°F (21-27°C), and lower humidity around 40-50% during flowering helps reduce mold and mildew risks.

  • Train early to manage its 5.2ft (160cm) height indoors.
  • Keep humidity low during bloom to protect dense flowers.
  • Use well-draining, nutrient-rich soil for healthy root growth.
  • Choose outdoor spots with long sunlight exposure.
  • Maintain steady warmth to support resin production.
