Green Crack Auto by Seedstockers

Green Crack Auto takes one of the most energetic American daytime strains and turns it into a fast autoflower. Built on Skunk #1 x Mango Indica genetics, it delivers bright tropical-citrus terpenes, skunky undertones and a sharp, clean energy lift that made the original a wake-and-bake staple.

Like any auto, it needs no light switch. Keep 18/6 or 20/4 from germination to the chop and the plant finishes in about 12 weeks from seed.

Expect a medium-sized plant with strong vertical growth, good lateral branching and frosted, compact buds. Yields reach 500–600 g/m² (1.64–1.97 oz/ft²) indoors and 120–220 g/plant (4.2–7.8 oz/plant) outdoors in a sunny spot.

THC sits in a moderate 14–22% range. The breeder rates this one for experienced growers because of its heavy late-flower feeding needs, so it is a great step up for anyone who already knows how to read a plant.

Lineage: Skunk #1 and Mango Indica

Skunk #1 is one of the foundational hybrids of modern cannabis, prized for vigor, stability and a pungent, skunky aroma. Mango Indica brings the tropical, fruity side of the profile and a dense bud structure.

Green Crack combined those traits into a famously energetic daytime hybrid, and Seedstockers carried the line into autoflower form. The result keeps the tropical-citrus terpenes and sharp effect while adding stable performance and predictable autoflower timing.

Aroma, Flavor and Effect

The aroma is loud tropical citrus layered over deep skunky undertones: bright, fruity and unmistakably Green Crack from mid-bloom onward.

On the palate, sharp citrus-mango leads, soft floral notes fill the middle and a spicy, herbal kick closes the exhale. It tastes a bit like a fresh mango and lime smoothie with a pinch of black pepper.

The effect is a clean, sharp rush that lights up the mind, boosts energy and keeps the body free and loose. It suits active days, creative work, errands and social sessions where staying sharp matters.

It is not a strain for winding down at night; it is built to get things moving.

Growing Green Crack Auto Indoors and Outdoors

Indoors, run 18/6 or 20/4; the breeder’s reference is LED on 20/4 for 500–600 g/m² (1.64–1.97 oz/ft²). Plant directly into the final container and give the strong vertical growth enough headroom.

Feeding is the key skill with this strain. It gets hungry in late flower, so increase potassium during bloom and watch the plant’s response closely. The breeder’s top tip is to keep a close eye on nitrogen from week 6: a controlled finish with tapering nitrogen reveals the deepest color and the brightest citrus terpenes.

Outdoors, use 15 L (4 gal) pots for 120–220 g/plant (4.2–7.8 oz/plant). Green Crack Auto loves sunshine and warm climates, where its citrus terpenes really pop. With its 12-week cycle, sow early enough to finish during warm, dry weather.

Good airflow and steady environmental control round out a successful grow, and the frosted, compact buds pay back the extra attention.
