The specs in one line: 21% THC, <2% CBD, 9-10 weeks flowering, 500g/m2 reported. Best indoor or outdoor. easy grow.

Eight growers logged this one as their go-to starter auto, and the numbers back them up: 21% THC in a 9–10 week flower window is a solid return for a plant that asks very little in return. Critical Kush Auto sits on the heavier, more sedating end of the indica spectrum — the kind of strain you harvest before the weather turns and crack open on a slow November evening. The citrus hits first on the nose, bright and slightly sharp, then settles into the earthy, resinous weight you'd expect from Kush heritage.

Indoors under decent light, 500 g/m² is realistic without dialling in anything complicated. It handles both indoor and outdoor setups, which makes it practical for Canadian growers who want to run a balcony crop through the summer and finish before September frosts. Rated easy — first-time autoflower growers will get a clean run without chasing pH or feed schedules obsessively.

THC Level & Potency

Critical Kush Auto delivers THC levels of 21%, placing it in the moderate-to-strong range that most regular consumers find comfortable.

Growing Critical Kush Auto

Critical Kush 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 9-10 weeks with yields of 500g/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 Auto features a citrus terpene profile that develops complexity throughout the flowering cycle. Bright lemon and orange zest punch through on the inhale, with a tangy, refreshing finish. 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 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. Consult a healthcare professional before using cannabis for medical purposes.
