Smell-first: crack the jar and you're hit with tangy citrus and a skunky sweetness that lingers longer than you'd expect from an autoflower. Green Crack Auto from Blimburn Seeds keeps that signature nose intact while trimming the timeline down to 7–9 weeks of flowering — fast enough for back-to-back runs in a single season. THC lands in the 20–25% range, which puts this firmly in the "don't underestimate it" category regardless of the auto format. Indoor growers pulling 400–500g/m² under a dialed setup won't be disappointed, and outdoor plants handle variable conditions reasonably well for a strain rated moderate difficulty.

The effect skews toward the head — alert, focused, moving — rather than the couch. That makes timing your harvest on the earlier side worth considering if you want to preserve that clarity. Best suited for intermediate growers comfortable managing feed schedules on a faster-than-photoperiod clock.

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day.

With THC levels reaching 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Green Crack Auto delivers THC levels of 20-25%, 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 minutes with a balanced head-and-body experience that evolves over time.

Growing Green Crack Auto

Green Crack Auto 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 400-500g/m2. Plants typically reach 60-100cm 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 45-55% 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

Green Crack Auto features a fruity, citrus, skunky, sweet terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. 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, Green Crack 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.
