The headline here is a classic sativa profile without the usual sativa penalty. You get the tall frame, the energetic high, and the generous yield, but the flowering time stays at a very manageable 8-10 weeks, where many pure Haze types drag on for twelve or more. That speed, inherited from Green Crack, is what makes the Super Green Crack strain practical as well as potent.

The Green Crack and Haze Parents of Super Green Crack
Green Crack is the engine of energy and speed. One of the most famously stimulating daytime sativas ever bred, it hands this cross its sharp, creative, euphoric lift, its vigorous growth, and the relatively fast finish that tames the Haze side. It is also where much of the uplifting, get-things-done character comes from.
Super Silver Haze, a multiple Cannabis Cup winner, brings the pedigree and the flavor. From it Super Green Crack inherits the tall, stretchy structure, the long, resin-frosted colas, and the spicy-citrus complexity woven through the earthy, tropical profile. It is the classic Haze backbone, refined and sped up by its partner.
Together they land firmly among Blimburn’s energetic sativa seeds and carry the full heritage of the catalog’s Haze strains, two legendary lines distilled into a single, grower-friendly plant.
Germination and the Vegetative Phase
Germinate with the paper-towel method at 70-79°F. Set the seeds between damp paper towels on a covered plate, keep them dark, and wait for taproots within 24 to 120 hours. Plant each half an inch deep in light, well-draining soil, taproot down.
Every Super Green Crack seed is feminized, so each plant flowers female. Veg under 18 hours of light, but keep this phase on the shorter side, because an 80% sativa stretches hard after the flip and a long veg can send it through the ceiling. Three to four weeks of veg is plenty for most indoor setups.
Train early while the plant is flexible. Top above the fourth node and use low-stress training or a net to spread the tall, Haze-driven growth sideways into an even canopy. This is the single most effective way to keep a 6.56 ft sativa under control and expose all those bud sites to light.
Growing Super Green Crack Indoors
Indoors, plan around the stretch. Flip to 12/12 while plants are still small, since the post-flip surge on an 80% sativa is dramatic and can double or triple the height. A screen pays for itself here, keeping the long colas level and well-lit.
Hold lights-on temperatures at 70-82°F to suit the tropical heritage, humidity at 50-60% in veg and 40-45% in bloom. Flowering runs 8-10 weeks, quick for this lineage, and good light penetration into the stretched canopy is key to filling the lower colas. Indoor yield reaches 1.15-1.64 oz/ft² (350-500 g/m²), high for a sativa when the canopy is managed well.
Growing Super Green Crack Outdoors
Outdoors, Super Green Crack wants a tropical-to-warm climate with a long, sunny season and a dry run into its October harvest. In the United States that suits Southern California, the Arizona low desert, Florida, and the warm Gulf Coast, regions with the heat and length a tall sativa needs to finish. Each plant can return a substantial 17.64 oz (500 g) of dried flower.
Give it full sun, a large container or open ground, and plenty of vertical room, as these Haze-driven genetics climb. Stake the main colas by mid-September, since the long sativa branches get heavy as they fill. The airy flower structure resists mold better than a dense indica, a welcome trait in a warm, humid tropical setting.
Flowering and Buds of Super Green Crack
Flowering shows the Haze side clearly. Super Green Crack forms long, spear-shaped colas that stretch and fill through the 8-10 week bloom rather than bulking into tight indica knots. They frost up steadily, carrying the resin that the Super Silver Haze lineage is known for.
The buds stay relatively airy, which is normal for a sativa of this pedigree and helps airflow through a tall plant. Keep light reaching the whole canopy and support the colas as they lengthen; the top flowers in particular can get long and heavy enough to lean by the finish.
Common Problems and Pro Tips
The defining challenge is height. An untrained Super Green Crack can overrun an indoor space fast, so early topping, low-stress training, and a net are close to essential rather than optional. Flip early, and do not let the veg phase run long if your ceiling is limited.
The airy Haze buds are a plus for mold resistance but can feel light if the canopy is poorly lit. Expert tip: treat this as a screen-of-green plant and chase light penetration above all. Spreading the canopy flat and keeping strong light on every cola is what turns a lanky sativa into the high-yielding producer the datasheet promises.
Feeding and Watering
Super Green Crack feeds moderately, with a light hand early and steady phosphorus and potassium through its longer sativa bloom.
| Stage | EC | pH | Notes |
|---|---|---|---|
| Seedling | 0.4-0.6 | 6.0-6.5 | Plain water or quarter-strength feed |
| Vegetative | 0.8-1.2 | 6.0-6.5 | Nitrogen-forward, add silica for stems |
| Preflower | 1.2-1.4 | 6.0-6.5 | Transition formula at the 12/12 flip |
| Bloom | 1.4-1.6 | 6.0-6.5 | Phosphorus and potassium forward |
| Flush | 0.0-0.4 | 6.0-6.5 | Final 10-14 days, plain water |
Water when the top inch of the medium dries, letting the pot lighten between rounds, since a tall plant drinks steadily. Sativas can be sensitive to overfeeding, so build nutrient strength up gradually and watch the leaf tips for early signs of excess.
Finish with 10-14 days of plain water at EC 0.0-0.4. The earthy, tropical profile is clean and nuanced, and a proper flush keeps the citrus-spice notes clear on the exhale.
Flavor, Terpenes, and Effects of Super Green Crack
The flavor is earthy and tropical, a classic sativa blend of fresh, zesty brightness over a grounded base. A broad terpene profile drives it. Terpinolene gives the signature fresh, almost piney Haze lift, limonene brings the tropical citrus, and pinene threads a crisp, resinous sharpness through the top. Humulene and delta-3-carene lay the earthy, woody foundation, caryophyllene adds a touch of pepper, and linalool and more round out the base.
The effect is pure daytime sativa. It opens creative, euphoric, and happy, genuinely stimulating and well suited to work, conversation, or getting outside, with the clear-headed drive Green Crack is famous for. At 19-21% THC it is satisfying without tipping into heaviness, and the forgiving, vigorous plant earns its beginner-suitable rating despite the tall sativa structure.
Harvesting, Drying, and Curing
Check trichomes from week eight, since a sativa like this often wants the full bloom. Harvest when most are cloudy with just a little amber to preserve the bright, energetic character; too much amber dulls the uplifting edge that defines the strain. Expect a staggered ripening down the long colas, so take the tops first.
Dry whole branches at 59-68°F and 50-55% humidity for 7-14 days in darkness with gentle airflow, waiting for stems that snap. Cure in glass for at least three weeks, burping daily early on; the earthy, tropical profile and its citrus-spice highlights sharpen and clean up noticeably with a patient cure.
What to Do With Your Trim
The Super Silver Haze resin makes the trim worth keeping. Dry-sift the sugar leaves for a zesty, tropical kief, run ice-water bags for hash, or press the sift into rosin to capture the bright terpinolene-and-limonene lift at full strength. With a yield this generous, the trim adds up fast.
