Green Crack Auto by FastBuds – Turbo-Charged Mango Flavor & Energetic High

Green Crack Auto by FastBuds is a sativa-dominant powerhouse that delivers turbo-charged energy, explosive mango flavor, and massive yields in just 9–10 weeks from seed to harvest—no light cycle changes needed.

Are you stuck with lazy highs and bland-tasting buds?

You want a strain that wakes you up, not weighs you down. Something that tastes as good as it makes you feel—fruity, spicy, and fresh, not skunky or stale.

Wasting weeks on slow-growing plants that barely deliver?

Most sativas take forever, stretch like crazy, and need expert care. You’re left waiting, trimming endless branches, and still ending up with airy buds and weak effects. And if you’re growing on a balcony or in a small space, height and smell become real problems.

Green Crack Auto delivers fast, frosty, and flavorful results—no stress, no waiting.

This autoflowering marvel packs the genetics of the legendary Green Crack into a compact, beginner-friendly plant that grows fast, stays under 0.90 m (3 ft), and produces up to 550 g/m² (1.94 oz/ft²) of dense, trichome-bombed bud. With a spicy-mango terpene profile and 20% THC, it’s the perfect daytime companion for focus, creativity, and good vibes.

Wake up your senses with every puff

Imagine cracking open a jar and getting hit with a wave of fresh mango, zesty citrus, and spicy florals. That’s Green Crack Auto. It’s not just loud—it’s delicious. The flavor carries through the smoke, smooth on the inhale, lip-smacking on the exhale. Whether you’re vaping or rolling a joint, this strain turns consumption into a sensory experience.

How to grow Green Crack Auto for maximum yield and flavor

1. Germinate seeds in a damp paper towel or starter cube—keep warm and dark for 24–72 hours.
2. Transplant to a final pot of 18–27 L (5–7 gal) early to avoid root stress—ideal for 420 Fast Buds Autoflowering Seeds.
3. Provide 18–20 hours of light daily—no need to switch to 12/12.
4. Use LST (Low Stress Training) early to spread the canopy and boost light exposure.
5. Avoid topping or aggressive pruning—autoflowers don’t recover well.
6. Watch for stretch in week 3–4—support side branches with soft ties if needed.
7. Flush with plain water 7–10 days before harvest to improve taste and smoothness.

• Thrives in both soil and coco, it adapts to your setup, which means you don’t need to overhaul your grow room to succeed.

Care, maintenance and storage

Keep humidity between 40–50% in flowering to prevent mold, especially in dense buds. Water when the top inch of soil feels dry—this strain loves to feed but hates wet feet. After harvest, dry slowly at 18–20 °C (64–68 °F) and 50–60% RH for 10–14 days, then cure in jars for 2–4 weeks, burping daily. For long-term storage, keep seeds in a cool, dark place—like your Bulk Seed Bank stash—for maximum viability.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Green Crack Auto in my 1.2 x 1.2 m (4x4 ft) tent under a 600W LED. I used 3-gallon pots and a SOG setup with 9 plants. I kept LST light—just bending the tops to open the canopy. No topping, no FIM—autoflowers don’t need the drama. I fed heavily during mid-flower and saw insane resin production by week 8. Harvested at 10 weeks: 512 g (18 oz) of frosty, mango-scented bud. The high was electric—perfect for writing, gaming, or hitting the gym. I’ve smoked better, but never grown better. This strain is a workhorse. My only tip? Don’t rush the dry—let those trichomes go milky with a touch of amber for the full cerebral punch.
