Description

The History of Critical Mass Auto Seeds

Certainly, their most successful strain in Spain, Critical Mass, was among the first strains in Mr. Nice’s seed catalog. It was developed as a better version of another classic, the Big Bud, and became one of the market’s top producers in the seed market.

Autoflowering Critical Mass Seeds’ Genetics Journey

Critical Mass was created in the 1990s by crossing Afghani and Skunk #1. This combination resulted in a high-yielding and potent strain.

Auto genetics contain the added cannabis Ruderalis

What is cannabis Ruderalis?

The three main Cannabis species are Cannabis sativa, Cannabis indica, and Cannabis Ruderalis. Ruderalis originates from regions with harsh climates like Eastern European and Russian climes. It is small, hardy, and autoflowering, meaning its transition from the vegetative phase to the flowering phase depends on age rather than light. Ruderalis’ unique traits make it useful in hybridizing strains, especially for generating durable, multi-environment autoflowering strains.

How to Germinate Critical Mass Seeds

  1. Before starting the germination process for Critical Mass seeds, gather all necessary materials, including Critical Mass seeds from a trusted source, high-quality paper towels, a plate, a plastic bag or lidded container, and distilled water.
  2. Moisten two paper towels with distilled water. It’s vital to keep towels moist but not too wet, as too much moisture can hinder germination. The paper towels help the seedlings absorb water, commencing germination.
  3. Distribute Critical Mass seeds evenly on a damp paper towel. Proper spacing prevents crowding and resource competition by giving seeds enough opportunity to thrive.
  4. Cover the seeds with a second moist paper towel to form a seed-paper towel sandwich. This sandwich structure keeps seeds wet, encouraging germination.
  5. After assembling the seed-laden paper towels, carefully move them to a dish. The plate is handy and stable, and it drains excess water from the seeds, preventing waterlogging, which can hinder germination.
  6. Place the plate in a plastic bag or container with a lid to store the seeds. The enclosed chamber protects seeds from outside pollutants and stabilizes the environment.
  7. Consider storing the seeds in a dark, warm place that fits germination conditions. The ideal temperature for this space is 70-85°F. Maintaining these conditions is essential for proper germination.
  8. Regularly check seeds for progress during the germination phase. Small white taproots should appear from seeds after 2–5 days, suggesting germination.
  9. After the taproots reach 1-2 cm, put the Critical Mass seedlings into the specified growing medium. Plant seeds with the taproot down and cover with light dirt.

Do autoflowers germinate differently than fems?

Although autoflowers and feminized cannabis seeds have different characteristics, they follow the same germination process, as they need moisture and warmth to grow.

The difference between Autoflower Critical Mass and Feminized Seeds

You don’t have to worry about hermies with Premium Cultivars Critical Mass autos.

Premium Cultivars’ Critical Mass autos minimize the risk of hermaphroditism. Hermies, or hermaphrodite plants, can produce male and female flowers, causing inadvertent pollination and decreased floral quality. Premium Cultivars’ Critical Mass autos’ autoflowering and meticulous breeding guarantee a more consistent and predictable growth pattern. Growers can avoid hermaphroditic characteristics and enjoy a set life cycle with auto-flowering seeds. This stability allows growers to focus on nutrient management and environmental conditions without worrying about hermies affecting the harvest.

Growing Critical Mass Auto Seeds

Should I Grow Critical Mass Autoflowering Seeds Indoors or Outdoors?

The decision to grow Critical Mass auto seeds indoors or outdoors depends on your preferences, as these seeds can thrive indoors and outdoors.

Growing Autoflowering Critical Mass Indoors

Growing Autoflowering Critical Mass indoors is convenient and efficient. Auto-flowering strains don’t need light cycles, making them ideal for indoor gardeners who can manage illumination. This strain takes 9-11 weeks to flower and be ready for harvest.

Growing Critical Mass Auto Seeds Outdoors

Growing Critical Mass Auto seeds outside is rewarding due to the strain’s endurance and adaptability to sunlight. These auto seeds take about 10-12 weeks to be ready for harvest.

The Best Grow Medium for Critical Mass Autoflowering Seeds

The optimal Critical Mass Autoflowering seed grow medium depends on the grower’s tastes, experience, and desired output. Beginners might prefer a well-balanced, nutrient-rich soil mix since it is more forgiving and requires less fertilization. Hydroponic systems like coco coir or perlite manage fertilizer distribution, accelerating growth. Expert growers choose soilless mixes to balance water retention and aeration. Maintaining pH and providing nutrients throughout the plant’s life cycle is crucial regardless of media.

The Best Climate for Critical Mass Auto Seeds

Critical Mass auto seeds require a temperature range of 68-80°F during the day and 7-9°F at night. Low humidity is necessary for these plants to flourish. Maintain 55%–60% relative humidity (RH) during the vegetative period. Lower RH to about 40% during the flowering phase.

Light Cycles for Critical Mass Auto

Critical Mass Auto seeds require 18-20 hours of light day during the vegetative stage, 12/12 light cycle during flowering. Auto-flowering Critical Mass Auto strains do not rely on light duration to flower, but a steady and appropriate light schedule promotes growth and yield.

Do Critical Mass Autoflowering Seeds Grow Faster?

Yes. Critical Mass Autoflowering seeds develop quicker than photoperiod ones. Autoflowering strains switch from vegetative to flowering depending on age rather than light cycles. This trait speeds plant growth, taking 8–12 weeks from seed to harvest.

What!? Autos can grow without dark time?

Autoflowering cannabis plants can grow without a dark period. Autos flower autonomously depends on age, unlike photoperiod strains that require a light cycle. This adaptability makes autoflowering strains suitable for indoor growers who may run continuous light cycles throughout the plant’s life.

Problems to Look Out For When Growing Critical Mass Autoflower Seeds

Growing Critical Mass Autoflower seeds requires constant monitoring for multiple plant concerns, such as nutrient deficits like nitrogen or calcium insufficiency, which can cause yellowing leaves or stunted development. Watch for white powdery mildew, tobacco mosaic virus, and mold in humid situations.

How Difficult is it to Grow Critical Mass Autoflowers?

Critical Mass Autoflowers are relatively easy to grow due to their powerful genetics, resilience, and forgiving temperament.

Are Critical Mass Auto Seeds Suitable for Beginners?

Beginners may find Critical Mass auto seeds appealing as they don’t require much experience to grow and achieve rewarding yields.

How Much Do Critical Mass Auto Seeds Yield?

Critical Mass auto seeds can yield 600 grams per m2 when grown indoors and an average of 120 grams per plant outdoors.

Do Autoflowering Critical Mass Seeds Yield Less than Regular and Feminized Seeds?

Autoflowering Critical Mass seeds tend to produce lower yields than regular and feminized seeds due to their shorter lifespan. Autoflowers have a faster harvest, but their compact form and short vegetative phase can affect plant size and production. The extended vegetative period of regular and feminized seeds allows plants to grow before flowering, which can increase yields.

How to Get Better Yields from Your Critical Mass Auto Seeds

Strategic cultivation and training techniques can boost Critical Mass Auto seed yields. For instance, you can introduce defoliation, Screen of Green, and Super Cropping to enhance plant growth.

The Best Grow Techniques for Critical Mass Auto

Screen of Green (SCROG)

The Screen of Green (SCROG) involves a horizontal screen or mesh that growers strategically place above plants during the vegetative phase. As plants develop, branches softly weave through the screen, creating an even canopy. This method is useful for managing plant height in indoor spaces with limited vertical space with Critical Mass Auto. SCROG ensures each bud site receives direct light, enabling consistent growth and larger yields. This technique also increases canopy air circulation, minimizing mold and mildew growth.

Super-cropping

Super cropping involves inducing controlled stress by gently twisting and bending plant branches. This technique can help Critical Mass Auto growers create a more resilient and adaptable plant. If the plant is bent purposely, its tissues transfer nutrients and energy to injured places, boosting resilience. Critical Mass Auto can benefit from this method as it helps manage plant height and prevents stretching. Super cropping promotes lateral growth, which increases cola production and harvest yield. Super cropping also evens the canopy height, distributing light equally across the plant. Controlled stress during super cropping causes the plant to create stronger stems, minimizing top-heavy plants and supporting budding buds.

Defoliation

Defoliation involves removing big fan leaves that block light penetration to lower bud sites to promote canopy-wide bud growth. This strategy helps Critical Mass Auto growers concentrate the plant’s energy on the most important places, resulting in thick, strong buds. Defoliation occurs during flowering once the plant has established a robust vegetative framework. Removing too many leaves can stress the plant. Defoliation maintains ventilation, decreases mold risk, and directs plant resources to the higher and mid-canopy, where the best buds emerge.

What does a Critical Mass plant look like?

Critical Mass matures into a compact Indica-dominant plant with broad, dark green leaves. The plant has tight, resinous buds clustering around multiple branch points to generate dense, robust colas. The plant has a modest height with thick, bushy foliage. Critical Mass plants are bright green throughout their lives, with occasional purple or blue leaves as they mature.

Where Can I Buy Critical Mass Autoflower Seeds?

If you’re looking for high-quality Critical Mass autoflower seeds, your ultimate destination should be Premium Cultivars, a reputable online seed bank.
