Lineage Green Crack x Super Silver Haze strain

Green Crack x Super Silver Haze, from the cross between Green Crack and Super Silver Haze, is a mostly Sativa strain (20% Indica / 80% Sativa). It tends to show an earthy, tropical flavor with a bright, mostly Sativa effect.

It also carries a Medium THC of 19% – 21%, making it a great choice for anyone looking for a happy experience with a good dose of energy.

Origin

Green Crack x Super Silver Haze combines the genetics of two legendary strains. Super Silver Haze, a champion variety, contributes Haze, Northern Lights and Skunk genetics, while Green Crack brings its potent, energizing Skunk heritage. The result is a well-rounded strain that inherits the best traits of both parents.

Known for its strong genetic background, Green Crack x Super Silver Haze is a top choice for growers seeking reliable feminized seeds, with robust genetics that perform well across a range of cultivation environments.

Green Crack x Super Silver Haze Sativa or Indica?

Green Crack x Super Silver Haze is a sativa-dominant hybrid (20% Indica / 80% Sativa). With Super Silver Haze contributing a predominantly sativa structure, the strain delivers an uplifting, energetic high, and Green Crack further sharpens those sativa characteristics, making it ideal for daytime use or whenever a creative boost is needed.

At the same time, the indica side inherited through Northern Lights adds a balancing touch, offering mild relaxation without sedation.

This blend of sativa and indica traits makes Green Crack x Super Silver Haze feminized seeds popular among both recreational and medicinal users.

Green Crack x Super Silver Haze Effects

Green Crack x Super Silver Haze effects are primarily creative, euphoric and happy. The sativa influence promotes a clear-headed, focused high that is perfect for productivity and creative tasks, and as it develops, users often feel increased motivation and a lift in mood.

Despite its uplifting nature, the strain’s indica undertones add a subtle, relaxing balance to the high. That duality makes it suitable for both day and evening use, with flexibility for a range of needs and occasions.

Green Crack x Super Silver Haze Flowering Time

Green Crack x Super Silver Haze feminized seeds have a moderate flowering time, fully maturing on average within 8 to 10 weeks. The sativa dominance may stretch the window slightly, but the reward is well worth the wait.

Under optimal conditions, the strain produces high yields of dense, resinous buds. With proper care, its genetics deliver excellent results both indoors and outdoors, which makes it a favorite among cultivators worldwide.

Germinating Green Crack x Super Silver Haze seeds

It is important to germinate your weed seeds carefully if you want to have a healthy harvest from day one. Although there are several methods to germinate our Feminized cannabis seeds, at Blimburn Seeds, we recommend our customers to follow our easy and simple technique. Before removing ourĀ Green Crack x Super Silver HazeĀ seeds from their packaging, remember that cannabis seeds are alive and delicate. Our hands are full of bacteria that can easily infect seeds and ruin our germination.

Set Up Your Germination Station:Ā Begin by moistening two paper towels with room temperature water. Lay one paper towel on a plate and spread the seeds on it, spacing them about 2 cm apart. Place the second paper towel on top of the seeds, and make sure to remove any excess water from the plate. Cover the setup with another opaque plate and store it in a warm, dark location.

Monitoring: Make sure paper towels are still moist by checking every 4-6 hours and spraying room temperature water. Typically, germination should occur within 24 to 120 hours. Once the seeds have sprouted tap roots, plant them with the roots facing down and cover with about 2 cm of soil. Remember to water the soil regularly by spraying to keep it moist. It may take up to two weeks for the plants to start growing.

Ideal Conditions: Maintain a consistent temperature of 70-90ĀŗF in the germination area. Use purified room temperature bottled water with a pH level between 5.5 and 6. Keep the seeds away from light, allowing exposure for less than 1 minute before and during germination. Avoid touching the seeds or applying pressure to them.

Record Keeping: To qualify for the three month germination guarantee, it is necessary to follow all the steps outlined in our germination guidelines. Please do not useĀ alternative germination methods, such as using a water bottle or planting directly into soil. Document the germination process through photography or video, as it will be requested when assessing claims for replacement products.

How to grow Green Crack x Super Silver Haze strain?

Green Crack x Super Silver Haze feminized seeds can be grown indoors or outdoors under optimal conditions, to avoid any problems during their development. Although they are robust and moderately easy to grow, we should always prevent any pests.

You can use different growing methods to retain and enhance the terpenes and flavors of your feminized Green Crack x Super Silver Haze buds.

  • Use a quality substrate. Perlite, peat or coco coir are ideal for moisture retention.
  • Thanks to the experience of our customers with our feminized Green Crack x Super Silver Haze seeds, we know that we can increase yields by up to 20%.

For optimal indoor cultivation, Blimburn Seeds advises wide, vertical spaces and the use of the ScrOG method to obtain a uniform canopy and increase the size of the lower flowers. If you plan to grow our feminized seeds outdoors, we have developed a grow guide for optimal cultivation in any area of the world.

Remember that our plants also need good nutrients as seedlings, in their vegetative period and finally in their flowering period.

When growing outdoors, choose the best date for your crop and a place where the plants receive the most hours of sunshine. If you prefer to grow indoors, use good tents, textile pots, led lighting, an air extractor to circulate clean air and, of course, a good carbon filter to avoid problems with neighbors or the law.

Keep daytime temperatures between 68-80 ℉ and nighttime temperatures 7 to 9 ℉ cooler than the day.

Feminized plants need low humidity to thrive. Keep relative humidity (RH) at 55%-60% during the vegetative phase, reduce it to around 40% during flowering and to about 30% by harvest.

Outdoors, growers in the Northern Hemisphere should sow in April to harvest in mid-October. Healthy feminized Green Crack x Super Silver Haze seeds produce about 17.64 oz/plant | 500 gr/plant of buds each.

Indoors, these crops have a flowering time of 8 – 10 weeks and produce about 1.15 – 1.64 oz/ft² | 350 – 500 gr/m².

Ideal Climate for Cultivating

Green Crack x Super Silver Haze flourishes in a tropical climate with hot summers and mild winters. The ideal temperature range is 70-85 ℉ (21-29 ā„ƒ), which promotes optimal growth. It adapts to various altitudes but thrives at lower elevations with stable, consistent sunlight. Suggested yearly rainfall is 30-40 inches (760-1020 mm), and well-draining soil is recommended to avoid root rot.

In the U.S., states with a near-perfect climate for this strain include California, Texas, Florida, Georgia, South Carolina, North Carolina and Louisiana. In these warm, humid conditions, Green Crack x Super Silver Haze seeds thrive, enhancing their potency and yield potential. With attention to climate, temperature, altitude and soil, growers can expect a healthy, abundant harvest of this distinctive Blimburn strain.

Green Crack x Super Silver Haze terpenes

Green Crack x Super Silver Haze carries an earthy, tropical aroma with a bright, zesty edge, built on a profile of eight terpenes, led by four dominant players that shape both its scent and its creative, euphoric effect.

Limonene brings a bright citrus-tropical note tied to an elevated, positive mood, driving the euphoric, happy lift and much of the fruity sweetness in the flavor.

Terpinolene adds a fresh, herbal-floral brightness, the classic Haze signature, linked to a clear, creative headspace.

Alpha-Pinene lends a sharp pine note tied to alertness and focus, the energetic Green Crack and Super Silver Haze edge that keeps the mind clear.

Caryophyllene contributes a warm, peppery spice and is the only terpene known to bind the body’s CB2 receptors, widely linked to easing tension and supporting the strain’s use for muscle spasms.

Rounding things out, Beta-Pinene adds extra fresh pine clarity, Delta-3-Carene a sweet, earthy cypress note, Humulene an earthy, hoppy warmth, and Linalool a soft floral calm that softens the comedown and supports restful sleep, giving Green Crack x Super Silver Haze an earthy, tropical aroma paired with a creative, euphoric and happy effect.
