Cannabis Seeds Glossary – Genetics, Phenotypes & Growing Terms.

 


Cannabis Seeds Glossary – Genetics, Phenotypes & Growing Terms.

Cannabis growing comes with a lot of terminology, and for new growers especially, it can feel overwhelming. Understanding the language around cannabis seeds, genetics, and plant behaviour makes it far easier to choose the right seeds, spot issues early, and grow with confidence.

At Discount Cannabis Seeds, we believe knowledge should be clear and accessible. This glossary explains the most important cannabis seed and growing terms, written in plain English — no unnecessary jargon.



Auto Flower.

Auto flower cannabis seeds produce plants that flower automatically based on age, rather than light cycle. Autos are fast-growing, compact, and popular with beginners.

Cannabinoids.

Naturally occurring compounds found in cannabis resin, including THC, CBD, CBG, and others. Cannabinoids influence effects, potency, and medicinal properties.

Clone.

A cutting taken from a cannabis plant and rooted to create a genetically identical copy. Clones provide uniform results, unlike seeds which produce variation.

Cotyledons.

The first small leaves that appear when a cannabis seed germinates. They provide early energy before true leaves develop.

Feminised Seeds.

Cannabis seeds bred to produce female plants only. Feminised seeds eliminate the need to identify and remove male plants.

F1, F2, F3 (Generations).

Breeding terms describing how many generations a strain has been worked.

  • F1: First-generation cross, usually most uniform
  • F2: More genetic variation
  • F3+: Increased diversity, sometimes less stability

Genetics.

The inherited traits inside a cannabis seeds that determine how a plant grows, flowers, smells, and performs.

Germination.

The process where a cannabis seed cracks open and produces a root and shoot. Healthy seeds usually germinate within 24–72 hours.

Hermaphrodite (Hermie).

A cannabis plant that produces both male and female flowers. This can occur due to genetics or extreme stress.

Hybrid.

A cannabis strain created by crossing indica and sativa genetics, combining traits from both.

Indica.

Traditionally refers to cannabis plants with shorter stature, dense buds, and relaxing effects. Modern breeding has blurred strict definitions.

Internodal Spacing.

The distance between nodes (branch points) on a cannabis plant. Short internodes often lead to denser bud stacking.

Light Cycle.

The schedule of light and darkness used during growing. Photoperiod cannabis plants require specific light cycles to flower.

Phenotype (Pheno).

The visible expression of a cannabis plant’s genetics. Plants from the same seed pack can show different phenotypes.

Photoperiod Seeds.

Cannabis seeds that require changes in light cycle to begin flowering. These plants offer greater control and recovery time.

Pistils.

Hair-like structures on female cannabis flowers that change colour as buds mature. Pistils help indicate flowering progress.

Resin.

Sticky substance produced by cannabis flowers containing cannabinoids and terpenes. Resin is responsible for potency and aroma.

Sativa.

Traditionally refers to taller cannabis plants with longer internodes and uplifting effects. Like indica, this term is now more descriptive than absolute.

Stability.

The consistency of a strain’s genetics. Stable cannabis seeds produce predictable growth and fewer extreme variations.

Stretch.

The rapid vertical growth cannabis plants experience when entering the flowering stage.

Terpenes.

Aromatic compounds that give cannabis its smell and flavour. Terpenes also influence perceived effects through the entourage effect.

Trichomes.

Tiny resin glands covering cannabis flowers. Trichomes contain cannabinoids and terpenes and give buds a frosty appearance.

Vegetative Stage (Veg).

The growth phase where cannabis plants focus on developing roots, leaves, and structure before flowering.

Viability.

The ability of a cannabis seed to germinate and grow into a healthy plant. Proper storage preserves viability.

Yield.
The amount of dried flower harvested from a cannabis plant. Yield is influenced by genetics, environment, and grower technique.

Why Understanding These Terms Matters.

  • Make informed buying decisions
  • Communicate problems accurately
  • Avoid common misunderstandings
  • Clear knowledge leads to better grows.
