The specs in one line: 21% THC, <2% CBD, 7-9 weeks flowering, 550g/m2 reported. Best indoor or outdoor. moderate grow.

Lineage: Critical x OG Kush, blended 80/20 indica-dominant by Original Harvest Seeds, this feminized variety has earned a practical reputation among growers who want consistent harvests without babysitting a temperamental plant. At 21% THC and a 7–9 week flower window, the numbers are straightforward — and so is the grow, rated moderate difficulty for indoor or outdoor runs in Canadian conditions. Indoor canopies have hit around 550 g/m², which is a genuinely strong return for the effort involved. The aroma profile stays firmly in earthy territory: think damp soil and mild spice rather than anything tropical or candy-sweet. Effects lean toward the sedating end of the spectrum, which lines up with the indica-heavy background.

Phenotype stability is reliable enough that cloning makes sense if you find a keeper from your first run. Best suited to growers moving past beginner autoflowers who want a productive indica with predictable structure and no major surprises.

Genetics & Lineage

Critical Kush traces its genetics to 80% Indica / 20% Sativa (Original Harvest Seeds). 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 Original Harvest Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric 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 21%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Critical Kush delivers THC levels of 21%, 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 Critical Kush

Critical Kush 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 7-9 weeks with yields of 550g/m2. Plants typically reach 100-160cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Critical Kush features a earthy terpene profile that develops complexity throughout the flowering cycle. The complex aromatic bouquet develops fully after proper curing. 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, Critical Kush 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.
