A Beginner’s Guide to the Cannabis Plant: Understanding the Basics

There’s a lot of information out there about the cannabis plant, and not all of it is accurate. Some people don’t know the difference between a male cannabis plant and a female one, while others think all cannabis plant leaves are the same. This guide walks you through the basics, from plant anatomy to legal considerations, so you can understand how long a cannabis plant takes to grow and much more without the confusion.

What Is the Cannabis Plant?

The cannabis plant is a flowering species that has been cultivated for centuries. It thrives in different climates and can grow both indoors and outdoors. Its structure includes stalks, cannabis plant leaves, and flowers.

This plant is dioecious, meaning it has separate male and female plants. The male cannabis plant produces pollen, while the female develops flowers. In cases where both reproductive organs are present, the plant is considered hermaphroditic. 

Growth cycles vary, with some plants taking longer to mature than others. Factors like genetics, environment, and cultivation methods influence how long a cannabis plant takes to grow. 

Types of Cannabis Plants

The cannabis plant comes in different varieties, each with distinct traits that affect its growth, structure, and use. Below is a breakdown of the most recognized types.

• Cannabis Sativa
• Key Characteristics: Tall, thin leaves, thrives in warm climates
• Growth Cycle: Longer (up to 16 weeks)
• Common Uses: Often cultivated for its high yield and diverse applications
• Cannabis Indica
• Key Characteristics: Short, bushy, with wide leaves
• Growth Cycle: Shorter (8–12 weeks)
• Common Uses: Known for its dense structure, making it popular for indoor growing
• Cannabis Ruderalis
• Key Characteristics: Small, wild-growing, naturally resistant to harsh conditions
• Growth Cycle: Very short (5–7 weeks)
• Common Uses: Primarily used in crossbreeding due to its auto-flowering genetics
• Hybrid
• Key Characteristics: A mix of sativa, indica, or ruderalis; can lean toward one parent strain or be balanced
• Growth Cycle: Varies depending on genetics
• Common Uses: Developed to achieve specific traits in cultivation

The cannabis sativa plant is known for its height and long flowering time, making it better suited for outdoor environments with warm temperatures. In contrast, cannabis indica has a compact structure with broad cannabis plant leaves, making it easier to grow indoors.

Cannabis ruderalis is the smallest of the three and is rarely cultivated on its own. However, it plays a crucial role in breeding because of its ability to flower automatically, regardless of light exposure. Hybrids combine traits from different types, allowing growers to select plants based on their needs.

Male vs. Female Cannabis Plants: What’s the Difference?

The cannabis plant is dioecious, meaning it produces separate male cannabis plants and female plants. Each plays a role in reproduction, but they have distinct characteristics that set them apart.

• Male Cannabis Plant
• Key Characteristics: Taller, thicker stalks, few cannabis plant leaves, pollen sacs form at nodes
• Role in Growth: Produces pollen for fertilizing female plants
• Common Uses: Used for breeding new strains and fiber production
• Female Cannabis Plant
• Key Characteristics: Shorter, bushier, develops flowers with hair-like pistils
• Role in Growth: Produces flowers, which contain the most desirable compounds
• Common Uses: Cultivated for commercial production
• Hermaphrodite
• Key Characteristics: Contains both male and female reproductive parts
• Role in Growth: Can self-pollinate, reducing genetic diversity
• Common Uses: Usually avoided as it leads to accidental pollination

For those studying or cultivating the cannabis plant, knowing the difference between a male vs female cannabis plant is important. Female plants are generally the focus since they produce flowers, while males are mainly used for breeding.

If a male cannabis plant is near females, it can release pollen and cause fertilization. This leads to seeded flowers, which most growers try to avoid. In some cases, stress can cause a female plant to become a hermaphrodite, developing both male and female parts. These plants can self-pollinate, which is why they are typically removed from controlled environments.

Identifying plant sex early is key to maintaining quality. Male plants develop pollen sacs at the nodes, while females produce white pistils where buds will form. Keeping them separate ensures better control over reproduction and plant development.

Anatomy of a Cannabis Plant

Every part of the cannabis plant plays a role in its growth and function. Whether it’s the cannabis plant leaves, flowers, or roots, each part contributes to the plant’s development:

Leaves

The primary function of cannabis plant leaves is photosynthesis, allowing the plant to absorb light and convert it into energy. The shape and size of the leaves depend on the plant type, with a cannabis sativa plant having long, thin leaves, while indica varieties have broader ones. Leaves are also a key indicator of plant health. They change color or wilting when something is wrong with water intake, nutrients, or environmental conditions.

Flowers (Buds)

Found only on female plants, cannabis flower contain the most desirable compounds. They are covered in trichomes, which appear as tiny crystals, and have pistils and bracts that play a role in reproduction. These buds develop during the flowering stage and continue to mature until harvest.

Stems & Branches

Stems and branches provide structural support for the plant, helping transport water and nutrients to the leaves and flowers. The thickness and strength of the stems vary by strain, with some varieties producing sturdy fibers used in other industries.

Roots

Roots absorb water and nutrients from the soil, ensuring the plant remains stable and well-fed. A strong root system is crucial for plant development, as weak or damaged roots can lead to poor growth. Proper watering and soil conditions help maintain a healthy root structure.

How Long Does a Cannabis Plant Take to Grow?

The time it takes for a cannabis plant to grow varies depending on the strain, environment, and care. On average, the full cycle takes between three to six months, with each stage playing a key role in its development.

Growth Stages of a Cannabis Plant

• Germination (1-7 days): The cannabis seed absorbs moisture, causing it to crack open and release a taproot. As the root anchors itself, a small sprout emerges, beginning the growth process.
• Seedling Stage (2-3 weeks): The first set of small cannabis plant leaves appears, often with only one blade per leaf. At this stage, the plant is delicate and requires proper light, humidity, and care to develop a strong foundation.
• Vegetative Stage (3-8 weeks): Growth accelerates, with stems and branches becoming thicker and more defined. More leaves develop, and a cannabis sativa plant tends to grow taller than other varieties. The plant focuses on strengthening its structure in preparation for the next stage.
• Flowering Stage (6-12 weeks): Buds begin forming on female plants, marking the final phase of growth. The plant shifts its energy from growing taller to producing flowers, which continue to develop until they reach maturity.
• Harvest & Drying (2-4 weeks): Once fully matured, the flowers are collected and dried to prepare for storage. Proper drying helps maintain quality and ensures the flowers are ready for use.

Factors That Affect Growth Time

• Strain Type: A cannabis sativa plant usually takes longer to mature than an indica variety.
• Growing Conditions: Light exposure, temperature, and humidity levels impact plant development.
• Plant Care: Nutrients, watering, and pruning influence how efficiently a plant grows.

Legal Considerations

Understanding the legal landscape surrounding the cannabis plant in Canada is essential for responsible engagement. Since the enactment of the Cannabis Act in October 2018, regulations have been established to control the production, distribution, sale, and possession of cannabis across the country. However, specific rules can vary by province and territory. Here's what you need to know:

Federal Framework

• Possession Limits: Adults aged 18 and over can possess up to 30 grams of dried cannabis or its equivalent in public.
• Home Cultivation: Individuals are permitted to cultivate up to four cannabis plants per household for personal use.
• Licensing Requirements: Commercial activities, including cultivation, processing, and sale for medical purposes, require appropriate licenses from Health Canada.

Provincial and Territorial Variations

While the federal government sets the overarching laws, provinces and territories have the authority to impose additional restrictions:

• Age Restrictions: Most provinces and territories have set the legal age for cannabis consumption at 19. However, Alberta allows consumption at 18, while Quebec has raised the legal age to 21.
• Home Cultivation: Quebec and Manitoba have prohibited home cultivation, overriding the federal allowance of four plants per household.
• Public Consumption: Regulations on where cannabis can be consumed vary. Some regions permit consumption in areas where tobacco smoking is allowed, while others have stricter bans, especially in public spaces frequented by children.

Retail Models

The approach to cannabis sales differs:

• Government-Run Stores: Provinces like Quebec and New Brunswick have government-operated retail outlets.
• Private Retailers: Alberta and Saskatchewan allow privately run stores under provincial oversight.
• Mixed Models: Some regions employ a combination of both systems.
