Spec sheet first — strain: sativa, seed type: autoflower, THC: 17-22%, yield band: medium, environment: indoor or outdoor.

Lineage: Green Crack Autoflower from Seed Supreme carries that classic sativa-leaning character into a ruderalis-crossed format that finishes seed-to-harvest in 8–10 weeks without any light-schedule management. That's a meaningful advantage if you're squeezing a late-season outdoor run in a shorter Canadian summer, or stacking multiple indoor cycles back-to-back. THC tests typically land in the 17–22% range, and indoor growers report yields around 400–550 g/m² when given a basic feed schedule and decent airflow.

The aroma profile is grounded — earthy with a clean sweetness underneath, nothing sharp or chemical. The grow itself is rated easy, so first-timers won't hit many walls, but experienced growers will appreciate how forgiving the structure is during stretch. Works indoors or out. Best suited to growers who want a straightforward autoflower with solid output and don't need hand-holding through the process.

Genetics & Lineage

Green Crack traces its genetics to Green Crack Autoflower (Seed Supreme genetics). This sativa-dominant autoflower seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Seed Supreme, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily energetic and creative effects, making this strain perfect for daytime use, creative projects, and staying productive. The cerebral lift arrives quickly, sharpening focus and inspiring motivation. With THC levels reaching 22%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Green Crack delivers THC levels of 17-22%, 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, starting as a cerebral buzz that gradually expands.

Growing Green Crack

Green Crack 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 8-10 weeks from seed with yields of 400-550 g/m². Plants typically reach 80-150 cm 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 features a earthy, sweet terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. 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 is commonly reported to help with depression, fatigue, lack of motivation, and ADHD symptoms. The uplifting, focusing effects make it popular among medical users seeking daytime functionality. 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 Green Crack?

This strain is ideal for beginner growers looking for a reliable, low-maintenance plant that delivers consistent results without advanced techniques. If you need a daytime boost for creativity and sustained focus, look no further.
