Germinating Critical 47 Seeds

It is important to germinate your Critical 47 cannabis seeds carefully if you want to have a healthy harvest from day one. Although there are several methods to germinate our Feminized cannabis seeds, from Blimburn Seeds we recommend our customers to follow our easy and simple technique.

Before removing our Critical 47 Feminized seeds from their packaging, remember that cannabis seeds are alive and delicate. The PH of our hands full of bacteria can easily infect them and ruin our germination.

Set Up Your Germination Station: 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 70-90ºF in the germination area. Use purified room temperature bottled water with a pH level between 5.5 and 7. 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 use 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.

Critical 47 Flowering Time

Critical 47 weed seeds are highly valued for their efficiency and reliability during cultivation. With a flowering time of 8-10 weeks, this strain strikes a perfect balance between speed and quality.

How to Grow Critical 47 strain?

Critical 47 Feminized seeds can be grown indoors or outdoors under optimal conditions, to avoid any problems during their development.

Although they are compact and robust, 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 Feminized Critical 47 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 Critical 47 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 Feminized 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 Feminized 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 Feminized 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.

Feminized 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 Feminized Critical 47 seeds produce about 2 – 4 oz/plant | 80 – 120 gr/plant of buds each.

Indoors, these crops have a flowering time of 8 – 10 weeks and produce about 1.47 – 1.82 oz/ft2 | 450 – 550 gr/m2.

Ideal Climate

Critical 47 is best cultivated in a warm, temperate climate that provides consistent sunlight and moderate humidity. The ideal temperature range for growing this strain is between 70–80°F (21–27°C). This temperature promotes vigorous growth and helps maximize yields. Critical 47 can tolerate fluctuations but thrives within this range. Adequate airflow and well draining soil are essential to prevent issues such as mold or root rot, ensuring a healthy crop.

In the United States, several states offer the perfect climate for cultivating Critical 47. These states include California, Oregon, Colorado, Nevada, Arizona, and Florida. Each of these regions boasts warm summers and mild transitions into autumn, creating an environment conducive to the thriving growth of Critical 47. By selecting a location in these ideal states with the right temperature and soil conditions, you can enhance your cultivation success and unlock the full potential of this resilient cannabis strain.

What does the Strain Smell Like?

The buds of Critical 47 are rock hard, soaked in resin and carry a crystalline sheen from the heavy coat of trichomes. The taste and flavor can be described as a blend of cheese, fruity, hashish and lemon notes.

Critical 47 makes a delicious, smooth smoke and delivers a strong, relaxing experience. Thanks to its large resin production, it is an ideal strain for the production of 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.

Cannabis Terpenes Critical 47 Strain

Critical 47 carries a complex aroma: bright lemon and fruity notes over a pungent cheese-and-hashish base, a nod to its Critical Mass and AK 47 heritage. Its six-terpene profile shapes that scent, and four lead, guiding both the aroma and its happy, relaxed and talkative character.

Limonene brings a bright, zesty lemon note that defines the strain’s citrus top end. Widely linked to an uplifted, positive mood, it drives the happy, talkative side of the high and lifts the pungent base.

Caryophyllene adds a warm, peppery, lightly spicy kick that captures the strain’s cheesy, hashish-like pungency. The only terpene known to bind the body’s CB2 receptors, it is often tied to easing tension and grounds the aroma with a savoury depth.

Myrcene anchors the blend with a soft, sweet and earthy depth that carries the fruity core. As the terpene most tied to body relaxation, it drives the calm, comfortable feel that defines this indica-leaning hybrid.

Linalool rounds things off with a soft, floral, lavender-like sweetness. Long associated with calm and relaxation, it smooths the effect into an easygoing, mellow finish beneath the citrus and cheese.

Together, these terpenes give Critical 47 a lemony, fruity aroma over a pungent cheese-and-hashish base, paired with a happy, relaxed and talkative effect made for easy evening use.
