Herbies Seeds runs this as a indica feminized line — 20-25% THC lab range, earthy/pine-dominant terps, 55-60 days from flip.

Lineage: Critical Mass × OG Kush, both heavy hitters on their own — together they produce a pure indica that's become a go-to for growers chasing volume without sacrificing potency. THC comes in consistently between 20–25%, and indoor plots regularly hit 650 g/m² when given proper canopy management. Flowering wraps up in 55–60 days, which is quick enough to fit a tight seasonal window for outdoor growers in shorter-summer provinces like Alberta or Manitoba.

The aroma leans earthy and pine-forward throughout the dry and cure — nothing tropical or candy-sweet here, just that classic resinous forest floor profile that old-school indica fans tend to prefer. Difficulty sits at moderate, so first-time growers can manage it, but you'll get the most from those yields if you've done at least one run before and know how to read a canopy. Best suited to growers who want a reliable, resin-heavy indica without fussing over a long flower window.

Genetics & Lineage

Critical Kush traces its genetics to Critical Kush (Barney's Farm 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 Herbies Seeds, 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

Critical Kush delivers THC levels of 20-25%, 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 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 55-60 days with yields of 650 g/m². Plants typically reach 80-150 cm 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, pine terpene profile that develops complexity throughout the flowering cycle. Sharp forest and resin notes create a fresh, invigorating flavor with earthy depth. 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.

Who Should Grow Critical Kush?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
