Cannabis Seeds – Everything You Need to Know

First Published on WEEDSPEEK.COM

This article will give you all the information you need to know about cannabis seeds, whether a beginner or an expert. Learn about what they are, how to determine the quality and more.

But first, let’s discuss what a cannabis seed becomes.

What is A Cannabis Plant, Anyway?

The cannabis plant is a species of the Cannabaceae family, which includes both hemp and marijuana. Cannabinoids found in the cannabis plant contain different compounds. The most abundant cannabinoid is tetrahydrocannabinol (THC), and it has psychoactive effects on humans.

What are Cannabis Seeds?

Cannabis is a plant that produces cannabis seeds. The seeds grow and harvest into marijuana and hemp plants.

Your cannabis seeds are fully grown and protected by an outer shell. Once they successfully germinate, or if the root breaks through the seed, they are ready to plant and grow.

They come in different forms, including regular, feminized & auto-flowering. Home growers of cannabis often choose to grow feminized seeds to ensure that the grown plant will be a healthy female.

Types of Cannabis Seeds

There are three types of cannabis seeds-auto flowering, photoperiod, and auto-flowering. The auto-flowering variety will flower according to its age rather than light cycles, whereas photoperiod cannabis plants require the change in light processes to trigger flowering. 

Autoflowering cannabis plants will flower regardless of light cycles – but they take much longer to reach maturity than photoperiod plants. It takes longer because they don’t adjust their growth according to changing lengths of day or night as photoperiod plants do.

What Factors Determine the Quality of a Cannabis Seed?

Cannabis seeds are the precursors for the weed that is grown. Categorized seeds go into different grades that depend on the quality of marijuana seeds. Factors that determine the quality of the seed include potency, flavor, and size.

Potency: The potency of the weed is determined by its THC content, which is measured in percentage (%). Marijuana with higher THC content is considered to be more potent than marijuana with lower THC content.

Flavor: The flavor of cannabis depends on its terpenes profile, determined by plant genetics and environmental factors like soil type, soil nutrients, sunlight intensity, and temperatures during the flowering period.

Size: Cannabis plants typically grow to around 3-4 feet in height, but some strains can grow up to 10 feet or more depending on their genetics and what you’ve been feeding the plant.

Anatomy of a Cannabis Seed

The anatomy of cannabis seed is a complex system responsible for regulating the plant’s growth. It starts with a few cells fertilized by male pollen and grows into a tiny, round embryo.

The embryo then sends out a long taproot to find soil and water and multiplies to seedlings. The root end of the seedling will then become anchored in the ground while the shoot end continues to grow upwards, reaching for sunlight.


What is Seedless Cannabis?

Cannabis plants are classified as male or female. Male cannabis plants produce pollen that fertilizes female cannabis plants, making the “seeds” from which new cannabis plants can grow.

An unfertilized female plant produces seedless cannabis. Unfertilized female plants mean that they will not pollinate and will not develop seeds.

There are two ways to do this: the first is to select a specific plant for breeding and use a hormone treatment on it. The other is to pollinate a male plant with a broader range of genes by taking pollen from one male plant and applying it to another female plant’s stamen. 

The latter method produces less uniformity in cannabinoids content but has been gaining popularity in recent years due to its efficacy and low production cost.

How do Cannabis Plants Reproduce?

There are three parts to the cannabis plant reproductive system: the male, female, and hermaphrodites. For a cannabis plant to reproduce, it needs at least one of each.

At the most basic level, when male pollen fertilizes a female flower’s ovule (or egg), this is when reproduction begins. Pollen and ova, in this case, do not come in contact with each other until the flower’s stigma and stamens open up. The process takes about 2-3 weeks after they’ve pollinated.

The fertilized flowers then produce seeds that will grow into new plants in about 3-4 weeks. Cannabis seeds will either need to be stored in cold storage (such as a refrigerator) or planted right away if the climate is warm enough for growth.

What is the Best Way to Store Cannabis Seeds?

Cannabis seed storage is a broad topic with many methods. Some people store them in coolers, jars, or ziplock bags. Some people also prefer to keep them in the freezer.

Here are some tips for storing cannabis seeds:

  • Store them in a dry, cool place like a refrigerator or freezer.
  • Keep them away from light to prevent the degradation of the THC-producing compounds in the seeds.
  • Protect them from moisture and heat by using an airtight container.
  • The best option is to store the seeds in vacuum-sealed containers with oxygen absorbers to prevent any deterioration in the quality and potency of the seeds.
