How Long Does It Take to Grow Weed?
The time it takes to grow weed depends on many factors, such as the environment, the equipment, the technique, and the strain.
Generally, the growth cycle of a cannabis plant can range from around 8 to 16 weeks, including both the vegetative and flowering stages. However, there are some differences between indoor and outdoor growing.
Indoor Growing
Indoor growing gives more control and flexibility over the conditions of the plants, such as light, temperature, humidity, and nutrients. The average time for indoor growing is about three to five months, but it can vary depending on the strain and the technique.
For example, some growers use the sea of green (SOG) or screen of green (SCROG) methods to maximize the space and light efficiency, which can reduce the time and increase the yield.
Outdoor Growing
Outdoor growing relies on the natural sunlight and climate, which can be unpredictable and variable. Outdoor growing typically requires less equipment and maintenance than indoor growing, but it can also produce lower quality and yield of buds.
The average time for outdoor growing is about four to six months, but it can vary depending on the strain and the season. For example, some growers use autoflowering strains, which can flower regardless of the light cycle, which can shorten the time and increase the harvests.
How Long Does It Take to Grow Weed: A Detailed Timeline
Here is a detailed timeline of how long it takes to grow marijuana:
Germination Stage
This is the stage when you plant your cannabis seeds and wait for them to sprout. It can take anywhere from 12 hours to 8 days depending on the quality and freshness of the seeds, the temperature and humidity of the environment, and the method of germination you use.
Some common methods are using paper towels, peat pellets, or rockwool cubes.
Seedling Stage
This is the stage when your sprouted seeds develop their first pair of true leaves and start to grow a stem and roots. It can last from 1 to 4 weeks depending on the strain, the light cycle, and the growing medium you use.
Seedlings need a lot of light, but not too much heat or nutrients, as they are very delicate and prone to stress.
Vegetative Growth
This is the stage when your plants grow rapidly and develop more branches, leaves, and nodes. It can last from 2 weeks to 6 months or more depending on whether you grow indoors or outdoors, the strain, the light cycle, and the training techniques you use.
Some cultivators opt to initiate the growing process from this stage by incorporating cannabis clones, sourced from reputable inventories. Mendocino cannabis’ clones inventory provides a diverse selection of genetically stable and high-quality clones, allowing growers to establish their crops with confidence and precision. The quality of the provided plants ensures robust genetics and healthy starts for successful cultivation.
Vegetative plants need a lot of light, water, and nutrients, as well as enough space and air circulation to prevent mold and pests.
Flowering Stage
This is the stage when your plants start to produce buds and resin glands that contain the cannabinoids and terpenes that give weed its effects and flavors. It can last from 6 weeks to 3 months or longer depending on the strain, the light cycle, and the growing conditions.
Flowering plants need less light, but more darkness, as well as less nitrogen, but more phosphorus and potassium, to boost bud production and quality.
Harvest and Curing
This is the stage when you cut down your plants, trim the buds, and dry and cure them to preserve their potency and aroma. It can take from 2 to 4 weeks or longer depending on the size and density of the buds, the humidity and temperature of the environment, and the method of drying and curing you use.
Harvesting and curing are very important steps that can make or break the final product, so you need to be careful and patient.

Factors Affecting the Growth of Weed
Here are some factors affecting the growth of weed:
Genetics and Strain
The genetic makeup of the weed plant determines its potential for growth, yield, potency, and resilience. Different strains have different characteristics, such as indica, sativa, or hybrid, that affect their morphology, flowering time, cannabinoid profile, and environmental preferences.
Choosing the right strain for your growing conditions and desired effects is crucial for a successful weed cultivation.
Growing Medium and Soil Quality
The growing medium is the material that supports the roots and provides water and nutrients to the weed plant. It can be soil, coco coir, perlite, vermiculite, rockwool, or hydroponic solution.
The quality of the growing medium affects the availability of oxygen, water, and nutrients to the roots, as well as the pH and electrical conductivity of the solution. A good growing medium should be well-drained, aerated, fertile, and free of pests and diseases.
Watering and Humidity
Water is essential for the weed plant’s growth, photosynthesis, and transpiration. However, too much or too little water can cause stress, wilting, nutrient deficiencies, root rot, mold, and reduced yield.
The optimal watering frequency and amount depend on the stage of growth, the size of the plant, the type of growing medium, the temperature, and the humidity.
The optimal humidity range for weed plants is 40-60%, but it can vary depending on the strain and the stage of growth.
Temperature and Climate
The optimal temperature range for weed plants is 20-28°C, but it can vary depending on the strain and the stage of growth. High temperatures can cause heat stress, reduced photosynthesis, nutrient burn, and lower potency, while low temperatures can cause cold stress, reduced growth, delayed flowering, and lower yield.
Climate is the long-term pattern of temperature, precipitation, wind, and other weather conditions in a given area. Different climates require different strategies for weed cultivation, such as indoor or outdoor, greenhouse or open field, and seasonal or year-round.
Light and Photoperiod
Light is the main source of energy for the weed plant’s photosynthesis, growth, and development. The quality, quantity, and duration of light affect the weed plant’s morphology, flowering time, and yield.
The more light the weed plant receives, the more energy it can produce, and the faster and bigger it can grow. However, too much light can cause light stress, bleaching, and nutrient burn.
The duration of light refers to the photoperiod or the length of the day and night cycle. Generally, weed plants need 18 hours of light and 6 hours of darkness for vegetative growth, and 12 hours of light and 12 hours of darkness for flowering.
Nutrients and Fertilization
Nutrients are the chemical elements that the weed plant needs for its growth, development, and reproduction. The main nutrients are nitrogen (N), phosphorus (P), and potassium (K), which are also known as macronutrients, as they are required in large amounts by the weed plant.
Fertilization is the process of adding nutrients to the growing medium or the water solution to supplement the weed plant’s needs. The optimal fertilization rate and frequency depend on the stage of growth, the type of growing medium, the quality of water, and the strain of weed.
Tips for Speed Up Weed Growth
Following are some tips to help you speed up your weed growth:
- Optimal Lighting: Ensure your cannabis plants receive the right amount and type of light during each growth stage. Consider using high-quality LED grow lights for efficiency.
- Proper Nutrients: Provide a balanced and specific nutrient regimen for your plants, adjusting the nutrient levels based on the growth phase. Nutrient-rich soil or hydroponic systems can enhance growth.
- Pruning and Training: Regularly prune your plants to remove unnecessary foliage and encourage better light penetration. Employ training techniques like topping and low-stress training to promote a bushier and more productive plant.
- Ideal Temperature and Humidity: Maintain a consistent and suitable environment for your cannabis plants. Keep the temperature within the optimal range and manage humidity levels to prevent mold and other issues that can slow growth.
- Quality Air Circulation: Ensure proper ventilation and air circulation in your growing space. This helps distribute CO2, prevents heat buildup, and strengthens the plant’s structure, ultimately promoting faster and healthier growth.
