Cannabis cultivation has been around for centuries, and it’s no secret that the time it takes for the plant to grow is a crucial factor in determining the quality and quantity of the end product. Whether you’re a seasoned cultivator or a newbie looking to grow cannabis, understanding the growth process is essential to achieving the desired results.
The time it takes for cannabis to grow can vary depending on several factors, including the strain, growing conditions, and cultivation method. However, it takes cannabis plants between 3 to 5 months to grow from seed to harvest. This time frame can be broken down into different stages, such as seedling, vegetative, and flowering, lasting different amounts of time. Generally, the vegetative stage lasts around 4 to 8 weeks, while the flowering stage can take anywhere from 6 to 12 weeks, depending on the strain.
So, how long does it take for cannabis to grow? The answer isn’t as straightforward as you might think. It depends on the strain, growing conditions, and cultivation method. However, with proper care and attention, you can expect your cannabis plant to take anywhere from a few months to over a year to reach maturity.
In this article, we’ll take a closer look at the growth stages of cannabis and what you can do to ensure a successful harvest.
Factors that affect cannabis growth
A variety of factors, including the following influences the growth of cannabis:
Strain
Different strains of cannabis have different growth rates. Some strains grow faster than others, while some take longer to mature. Indica strains, for example, tend to have a shorter flowering period than Sativa strains.
Growing conditions
The environment in which cannabis is grown can significantly impact its growth rate. Factors such as temperature, humidity, lighting, and air circulation can all affect how quickly the plant grows.

Cultivation method
How you grow your cannabis can also affect its growth rate. For example, growing cannabis hydroponically (in water) can speed up the growth process, while growing it in soil may slow it down.
Cannabis growth stages
Cannabis goes through several growth stages before it is ready for harvest. Understanding these stages is important to ensure that you provide your plants with the care and attention they need to thrive. The four main growth stages of cannabis are:
Germination stage
The germination stage is the first stage of cannabis growth. The seed begins to sprout during this stage, and the taproot emerges. This stage typically lasts for 1-2 weeks.
To germinate your cannabis seeds, you can soak them in water for 24 hours and then plant them in a growing medium. Keep the soil moist but not soaked, and make sure to provide your plants with plenty of light.
Seedling stage
The seedling stage is the second stage of cannabis growth. During this stage, the plant begins to develop its first leaves and begins to grow taller. This stage typically lasts for 2-3 weeks.
To care for your cannabis seedlings, make sure to keep the soil moist and provide them with plenty of light. You may also need to feed them with a nutrient solution to ensure that they get the nutrients they need to grow.
Vegetative stage
The vegetative stage is the third stage of cannabis growth. During this stage, the plant develops its branches and leaves and begins to grow more rapidly. This stage typically lasts for 4-8 weeks.
To care for your cannabis plants during the vegetative stage, provide them with plenty of light and nutrients. You may also need to train your plants by tying them down or pruning them to encourage bushier growth.
Flowering stage
The flowering stage is the final stage of cannabis growth. During this stage, the plant begins to produce flowers, which contain cannabinoids that are used for medicinal and recreational purposes. This stage typically lasts for 6-12 weeks.
To care for your cannabis plants during the flowering stage, provide them with plenty of light and nutrients. You may also need to adjust the lighting schedule to ensure the plants get the right light daily.

Harvesting and curing
Once your cannabis plants have reached maturity, it’s time to harvest them. Harvesting involves cutting the plant down and removing the flowers, which can be dried and cured before use. Proper harvesting and curing are essential to ensuring that your cannabis is of high quality and potency.
To harvest your cannabis, use a sharp pair of scissors or pruning shears to cut the plant at the base of the stem. Hang the plant upside down in a cool, dry place for several days. Once the plant is dry, remove the flowers and place them in a jar to cure for several weeks.
Timeframe for cannabis growth
The amount of time it takes for cannabis to grow depends on several factors, including the strain, growing conditions, and cultivation method. Generally, you can expect your cannabis plant to take 3-12 months to reach maturity.
Indoor cannabis plants tend to grow faster than outdoor plants, as you have more control over the growing conditions. However, indoor cultivation can be more expensive and requires more equipment.
Tips for speeding up cannabis growth
If you’re looking to speed up the growth of your cannabis plants, there are several things you can do:
- Choose a fast-growing strain
- Provide your plants with plenty of light
- Use a high-quality growing medium
- Keep the temperature and humidity levels consistent
- Use a nutrient-rich soil or nutrient solution
- Train your plants to encourage bushier growth
Conclusion
In conclusion, understanding the growth stages of cannabis is essential to achieving a successful harvest. While the time it takes for cannabis to grow can vary based on several factors, with proper care and attention, you can expect your plants to take anywhere from a few months to over a year to reach maturity.
Whether you’re a seasoned cultivator or a newbie, following the tips outlined in this article can help you achieve a bountiful harvest of high-quality cannabis.
