How Cannabis Seeds Develop – From Pollination to Mature Genetics.

 

How Cannabis Seeds Develop – From Pollination to Mature Genetics.


Most growers focus on what happens after germination — but few understand what happens before a cannabis seed ever reaches your hand.

Understanding how cannabis seeds develop helps growers make better buying decisions, predict stability and appreciate why some genetics perform more reliably than others.

At Discount Cannabis Seeds, we prioritise carefully selected, stable genetics. In this guide, we’ll explain how cannabis seeds are formed, how traits are inherited and what makes a mature seed viable.



Stage 1: Pollination – Where It All Begins.

Cannabis seeds form when pollen from a male plant fertilises a female flower.

The process:

Male plant releases pollen.

Pollen reaches receptive female pistils.

Fertilisation occurs.

The plant diverts energy into seed production.

Once fertilised, the female plant stops prioritising resin-heavy bud growth and instead focuses on producing mature seeds.

This is why seeded flowers contain less resin than sensimilla (seedless) flowers.

Stage 2: Genetic Combination.

Each cannabis seed contains:

  • 50% genetic material from the male parent
  • 50% genetic material from the female parent
  • These genes determine:
  • Plant height
  • Internodal spacing
  • Resin production
  • Cannabinoid ratios
  • Terpene expression
  • Flowering time
  • Stress tolerance
  • If breeding is controlled and stabilised over generations, traits become predictable.

If breeding is rushed or unstable, offspring show high variation.

Stage 3: Seed Development & Maturation.

After pollination, cannabis seeds take around 4–6 weeks to fully mature.

A mature seed typically:

  • Turns dark brown or mottled
  • Develops a hard outer shell
  • Forms internal nutrient reserves
  • Completes embryonic development
  • Immature seeds are often pale, soft and unlikely to germinate successfully.
  • Maturity directly affects viability.

Stage 4: Dormancy.

Once fully developed, cannabis seeds enter a natural dormant state.

Inside the shell:

  • The embryo remains alive but inactive
  • Stored carbohydrates provide early energy
  • Protective layers guard against moisture and damage
  • Proper storage maintains this dormancy until germination begins.

Stage 5: Germination Activation.

When exposed to moisture, warmth and oxygen:

  • The seed absorbs water
  • Metabolic processes activate
  • The shell softens
  • The taproot emerges
  • Genetic strength influences how quickly and successfully this process occurs.

Why Seed Development Affects Performance.

How a cannabis seed is bred and matured impacts:

  • Germination rates
  • Early root vigour
  • Seedling strength
  • Stress resistance
  • Growth uniformity

Professionally produced seeds are:

  • Fully matured
  • Properly dried
  • Carefully stored
  • Tested for viability

Poorly produced seeds may crack, stall or fail to sprout.

Stable vs Unstable Seed Development.

Stable seeds come from:

  • Multiple generations of selection
  • Controlled pollination
  • Phenotype testing
  • Trait reinforcement
  • Unstable seeds often result from:
  • Accidental pollination
  • Poor genetic selection
  • Limited testing
  • Inconsistent parent plants
  • Stability determines long-term reliability.

Environmental Influence During Seed Formation.

Even before harvest, environment affects seed quality:

  • Nutrient balance impacts embryo strength
  • Temperature affects maturation
  • Humidity influences drying quality
  • Well-developed cannabis seeds begin with healthy parent plants.

Signs of High-Quality Cannabis Seeds.

Before planting, look for:

  • Dark, firm outer shell
  • Slight mottling or striping
  • No cracks or damage
  • Uniform size
  • Seed quality reflects breeding standards.
