Growing Life Cycle of Cannabis


Growing marijuana is an exciting journey. Here’s a simple guide to help you learn about the different stages of a cannabis plant’s life cycle.

Overview of the Growth Cycle

The cannabis growth cycle varies with indoor, outdoor, or greenhouse cultivation. Indoors, you control the environment for earlier flowering. Outdoors, plants rely on natural light and seasons. Greenhouses blend both methods with light manipulation. Growing takes 4-8 months, but using auto-flower strains or clones can shorten this. Outdoor harvests often occur in October, called “Croptober.” Know about marijuana delivery service

Cannabis Plant Growth Stages

Marijuana plants start as seeds when a male plant fertilizes a female. Weed seeds are durable but can be harmed if exposed to freezing temperatures for too long.


This first stage is germination. You need to expose the seeds to moisture and light. This encourages the seed to sprout. Soil is not necessary for germination, but nutrients are needed once growth starts. The germination phase is usually marked by the appearance of two small leaves called cotyledons above the soil.

Seedling Stage

Next is the seedling stage, lasting about 2-3 weeks. During this time, the plant grows more leaves, which are essential for photosynthesis. The seedling stage requires a lot of light, usually 18-24 hours a day, and proper care to ensure the plant grows strong and healthy.

Vegetative Stage

This phase can last from a few weeks to several months, depending on the growing conditions and the strain. During this phase, the plant focuses on growing leaves and stems. It’s crucial to provide the plant with plenty of light, nutrients, and water to support its rapid growth.

Pre-flowering Stage

The pre-flowering stage lasts 1-2 weeks and bridges the vegetative and flowering phases. During this stage, female plants grow white pistils, while male plants develop small sacs. Removing male plants prevents fertilization, ensuring better harvest quality and yield.

Flowering Stage

During the flowering stage, the plant produces buds over 6-10 weeks, depending on the strain and conditions. It needs about 12 hours of light and 12 hours of darkness each day. Providing the right nutrients and care during this phase is crucial for a good harvest.


The final stage is harvesting. This stage occurs when the buds are fully developed and ready to be picked. Signs that the plant is ready for harvest include the pistils turning a reddish-brown colour and the trichomes (small resin glands) changing from clear to milky or amber. After harvesting, the buds need to be dried and cured to improve their flavour.

Growing Marijuana

During the flowering stage, the plant starts to produce buds. This stage typically lasts 6-10 weeks, depending on the strain and growing conditions. The plant will need less light, usually about 12 hours of light and 12 hours of darkness each day. It’s important to continue providing the plant with the right nutrients and care during this phase to ensure a good harvest.

By following these stages, you can ensure a successful marijuana-growing experience and high-quality harvest.
