Lineage Green Crack Fast Version strain

Green Crack Fast Version, resulting from the cross between Green Crack Auto x Green Crack, is a mostly Sativa strain. The strain will likely have a citrus, earthy and tropical flavor with a strong, uplifting Sativa-leaning high.

It also has a Medium THC 12% – 18%, making it a great choice for those looking for a strong and relaxing experience.

Origin

The Green Crack Fast Version strain is a quick-flowering variety derived from the renowned Green Crack, a strain with a celebrated history.

Originating in the United States in the 1990s, Green Crack was created from a Skunk #1 phenotype, a lineage known for its sharp, energetic and focused effects. This fast version retains the essence of the original while offering a much shorter flowering period, making it a favorite for growers seeking a quicker harvest.

Also referred to as “Green Crush” or “Mango Crack,” the strain’s genetics are designed for medicinal use, particularly in addressing Arthritis, Depression and Fatigue. Its unique origin and carefully bred lineage have solidified its status in the cannabis world.

Green Crack Fast Version Sativa or Indica?

The Green Crack Fast Version strain leans predominantly towards the sativa side of the spectrum, 60% Indica / 40% Sativa, with genetics that produce invigorating and cerebral effects. Like the original Green Crack, this version is known for providing a mental boost and enhancing focus, making it a great choice for daytime use.

However, despite its sativa dominance, this fast version also carries some indica characteristics, offering a mild body relaxation that balances out the energetic high. Its hybrid nature, combining sativa and indica elements, ensures a well-rounded experience for users.

Green Crack Fast Version Effects

Green Crack Fast Version feminized seeds produce a strain that delivers sharp, energetic and uplifting effects. Known for its potent sativa influence, users typically experience increased focus, creativity and an overall sense of euphoria, often with a boost in appetite. It’s a popular choice for daytime use, helping combat fatigue and stress while keeping the mind clear and sharp.

In addition to its mental effects, this strain offers subtle physical relaxation, providing relief without heavy sedation. This balance of mental stimulation and bodily calm makes it an excellent option for those seeking both medicinal and recreational benefits.

Germinating Green Crack Fast Version 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 Fast VersionĀ 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.

Green Crack Fast Version Flowering Time

One of the standout features of the Green Crack Fast Version strain is its significantly reduced flowering time.

On average, this strain completes its flowering cycle in about 8 to 10 weeks, much faster than the original Green Crack. This shorter growth period makes it an attractive option for growers looking to harvest in less time without compromising on quality.

Green Crack Fast Version feminized seeds produce plants that are easy to manage, offering the same potency and yield as the original strain while allowing for a quicker turnaround. Its fast flowering time and robust genetics make it a favorite among both novice and experienced growers.

How to grow Green Crack Fast Version strain?

Green Crack Fast VersionĀ seeds can be grown indoors or outdoors under optimal conditions, to avoid any problems during their development. Although they are moderately easy to grow and hardy, we should always prevent any pests.

You can use different growing methods to retain and enhance the terpenes and flavors of your Green Crack Fast Version buds.

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

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

Remember that our cannabis plants also need good nutrients when our Fast Flowering seeds are seedlings, in their vegetative period and finally in their flowering period.

When you grow cannabis seeds outdoors, choose the best date for your crop, a place where our cannabis plants receive the most hours of sunshine.

If on the other hand you like to grow your Fast Flowering seeds indoors and you have good tents, textile pots for growing, led lighting, 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.

Fast Flowering plants need low humidity to thrive. Keep relative humidity (RH) levels at 55%-60% during the vegetative phase. Reduce RH to around 40% during the flowering phase. By harvest time, you can reduce RH to 30%.

Outdoors, breeders in the northern hemisphere should sow their cannabis seeds in April for harvest in mid October. Healthy Green Crack Fast Version seeds produce about 17 – 26 oz/plant | 500 – 750 gr/plant of buds each.

Indoors, these crops have a flowering cycle of 8 – 10 weeks and produce about 1.31 – 1.97 oz/ft2 | 400 – 600 gr/m2.

If you plan to grow our feminized seeds outdoors, we have developed aĀ grow guideĀ for optimal cultivation in any area of the world.

Ideal Climate for Cultivating

The Green Crack Fast Version strain flourishes best in a climate that mimics the Tropical or a seasonal environment with warm summers and mild to cool winters. The ideal temperature range for growing this strain is between 70-85°F (21-29°C), as this range guarantees optimal growth and yield. Paying attention to the relative humidity is also crucial. A drier climate will enhance the quality of your buds and prevent bud rot.

For aspiring growers in the U.S., states with fitting climates include California, Nevada, Oregon, Arizona, and Florida. These states enjoy the perfect balance of sunshine and rainfall, ideal for producing high quality Green Crack Fast Version buds. However, this strain is quite versatile and can also be cultivated indoors with the right setup and care.

What does the strain smell like?

The buds of Green Crack Fast Version are rock hard, soaked in resin and carry a crystalline sheen from the heavy coat of trichomes. The flavor is a blend of citrus, earthy and tropical notes, with an aroma of sweet-and-sour mango and exotic fruit.

Green Crack Fast Version makes a smooth, soft smoke and combines a wide range of effects for a sharp, energetic experience. Thanks to its high resin production, it is a good choice for high-quality extracts and concentrates.

A good terpene profile enhances the flavors of the buds of cannabis plants. Terpenes are volatile organic compounds that are produced in the cannabis plant and have an effect on the aroma and flavor of the buds.

These terpenes act as a kind of energizer for the flavors of the buds, as they add a fresh, citrusy touch to the sweeter flavors found in the buds. On the other hand, terpenes also have an effect on the effect that cannabis produces when smoked, as some terpenes have sedative properties, while others can act as stimulants.

For this reason, it is important to know the different terpenes found in a given cannabis strain before smoking it, in order to get the most out of the flavors and effects they produce.

Green Crack Fast Version terpenes

Several terpenes shape this profile, and three of them lead, driving both the aroma and its energetic, focused and uplifting character.

Limonene leads with a bright, zesty citrus note that gives the strain its fresh, tropical top end. Widely associated with an uplifting, mood-boosting feel, it drives the euphoric, energetic side of the experience.

Terpinolene adds a fresh, fruity and lightly herbal lift that reinforces the strain’s tropical, mango-like character. Often tied to an energizing, creative feel, it supports the clear, focused, daytime side of the high.

Alpha-Pinene brings a crisp, sharp pine note with a herbal edge. Often associated with alertness and mental focus, it reinforces the strain’s clear-headed, functional character.

Together, these terpenes give Green Crack Fast Version its signature lift: a zesty citrus-and-mango aroma over an earthy base, paired with an energetic, focused and uplifting effect made for daytime use.

How To Grow Green Crack Fast Version

Read Now

A Fast Version is a photoperiod strain that has been crossed with a select autoflower to dramatically shorten its flowering time, but it does not become an autoflower itself. This means you still have full control over the vegetative period to grow a large plant, but once you switch the lights to a 12/12 schedule, it will finish flowering in just 6-7 weeks. This is significantly faster than the already-quick original, allowing for incredibly fast harvests.

Green Crack grows like a classic Sativa: tall, fast, and stretchy, with a vibrant light-green color. It is not a compact plant. Expect it to at least double in size during the flowering stretch, developing long, elegant branches with a very high bud-to-leaf ratio. Its open structure provides excellent airflow, making it naturally resistant to mold.

Yes, it’s an excellent choice for an ambitious beginner. While its rapid stretch requires some attention and training (like topping or LST), Green Crack is famously resilient, vigorous, and forgiving. It’s very resistant to pests and mold and reliably produces large yields even with minor mistakes. This Fast Version makes it even easier by reducing the time for potential problems.

Managing its vigorous vertical growth is the key to maximizing your indoor yield. We highly recommend topping the plant at least once during the vegetative stage to create a wider, more manageable canopy. From there, its long and flexible branches are absolutely perfect for a ScrOG (Screen of Green) setup. By weaving the branches through the net during the stretch, you can create a massive, flat plane of dense, top-shelf, mango-scented buds.
