If you’re looking to grow your cannabis plants, understanding the different cannabis growth stages is crucial. Whether you’re a beginner or an experienced grower, knowing how your plants develop over time can help you achieve the best yields and the healthiest plants. In this complete guide, we’ll explore each stage of cannabis growth, provide expert tips, and answer all your questions about cannabis cultivation.
What are the different stages of Cannabis growth?
Cannabis growth can be broken down into several distinct stages, each of which is vital for the overall development of your plant. These stages include:
- Germination
- Seedling
- Vegetative
- Flowering
- Harvesting
Let’s dive deeper into each of these stages to better understand what happens and how to optimize your growing conditions for the best results.
1. Germination stage: The beginning of life
The germination stage is the first step in the cannabis growth process. This is when the seed begins to sprout and develop its first root and stem. Typically, this stage lasts about 3 to 10 days. The key to successful germination is providing the right conditions: warmth, moisture, and a stable environment.
How to germinate Cannabis seeds
To germinate cannabis seeds, you can use various methods such as the paper towel method, placing seeds directly into water, or using a soil or growing medium that retains moisture. Here’s how you can do it:
- Soak your cannabis seeds in water for about 12-24 hours.
- Place them on a damp paper towel and fold it over the seeds.
- Store the paper towel in a warm area (ideally 70-85°F or 21-29°C).
- Check daily to ensure the seeds are moist, and after a few days, you should see the seed split open and a small root emerging.
Once the seedling has developed its taproot, it’s time to move on to the next stage.
2. Seedling stage: The first leaves appear
Once the seed has sprouted, it enters the seedling stage. This is when the cannabis plant begins to grow its first true leaves, which are typically single-fingered. During this stage, the plant is very delicate and sensitive to environmental factors such as light, temperature, and moisture.
Tips for growing Healthy Seedlings
- Light: Keep your seedlings under a light source with a gentle intensity. Too much light can cause the seedling to burn.
- Temperature: Ensure that the temperature stays between 70-80°F (21-26°C).
- Humidity: Seedlings thrive in high humidity, around 65-70%. This helps them take up water and nutrients more efficiently.
At this stage, your cannabis plant is still very young, so make sure to avoid overwatering. Let the soil dry out slightly between waterings.
3. Vegetative stage: Growth and expansion
The vegetative stage is the phase where your cannabis plant begins to grow rapidly. This stage can last anywhere from a few weeks to several months, depending on the strain and growing conditions. During this time, the plant focuses on building its root system and increasing the number of leaves.
What Happens during the Vegetative stage?
- The plant’s roots expand, allowing it to absorb more nutrients.
- The plant begins to grow tall and strong.
- It develops a robust network of leaves, branches, and stems, all essential for photosynthesis.
In this stage, you’ll also want to consider pruning your plant to encourage healthy growth and maximize your yields later on. If you’re growing indoors, providing around 18-24 hours of light each day can encourage your plant to thrive.
How to care for your Cannabis plants in the Vegetative stage
- Lighting: Use high-quality grow lights to mimic natural sunlight. Keep the light cycle consistent to avoid stressing the plants.
- Nutrients: Cannabis plants in the vegetative stage need nitrogen-rich fertilizers to help them grow strong. Be sure to choose fertilizers that are formulated for this stage.
- Watering: Keep the soil moist, but don’t overwater. Allow the soil to dry out between waterings to promote healthy root growth.
4. Flowering stage: Bud development
After the vegetative stage, cannabis plants transition into the flowering stage. This is where the magic happens. The plant focuses all of its energy on developing buds, which contain the valuable cannabinoids and terpenes that growers are after.
What to expect during the Flowering stage
- The male and female plants begin to show distinct features. Female plants will start developing pistils (the white hairs that appear at the nodes), while male plants will develop pollen sacs.
- This stage can last anywhere from 8 to 12 weeks, depending on the strain.
- The plant will require different nutrients, specifically phosphorus and potassium, to help the buds develop.
If you’re growing cannabis indoors, consider changing the light cycle to 12 hours of light and 12 hours of darkness to trigger flowering. For outdoor growers, make sure the plants are getting enough sunlight during the growing season.
Optimizing flowering for maximum yields
- Temperature: Keep temperatures between 65-80°F (18-26°C). Avoid letting the temperature fluctuate too much during the flowering phase.
- Humidity: Reduce humidity to around 40-50% to avoid mold growth on your buds.
- Nutrients: Switch to a bloom-specific nutrient mix with higher amounts of phosphorus and potassium to encourage bud production.
During this phase, many growers also implement techniques like training (such as Low Stress Training, or LST) to ensure their plants grow evenly and maximize light exposure to the buds.
5. Harvesting: When to pick your Cannabis buds
The harvesting stage is the final step in the cannabis growth process. You’ll know it’s time to harvest when the trichomes (tiny resin glands on the buds) turn from clear to milky white, and some may even turn amber. The timing of your harvest will affect the potency and flavor of your cannabis.
How to harvest Cannabis
- Check the Trichomes: Use a magnifying glass or jeweler’s loupe to inspect the trichomes. When they are mostly milky, with some turning amber, it’s time to harvest.
- Cut the Plant: Use sharp scissors or pruning shears to cut the branches of the plant.
- Drying: Hang the branches in a dark, well-ventilated area to dry. This process usually takes 7-10 days.
- Curing: After the buds are dried, they should be cured in glass jars for 2-4 weeks to enhance their flavor and potency.
During the harvest, be careful not to damage the buds, as they are fragile and contain the most valuable compounds.
How long is a Cannabis full grow cycle on average?
The average full cannabis grow cycle can take anywhere from 3 to 6 months, depending on the strain and environmental factors. Generally, the process can be broken down into several key stages: germination, seedling, vegetative, preflower, flowering, and finally, harvest. But what does each stage involve, and how can you manage them for the best results?
Cannabis Germination stage (2-10 Days)
The first stage of cannabis growth is germination, a critical step that can take anywhere from 2 to 10 days, depending on factors like temperature and moisture. During this phase, the seed absorbs water and begins to sprout. But how long does it take to germinate cannabis seeds?
How Long Does it Take to Germinate Cannabis Seeds?
On average, it takes about 5-7 days for cannabis seeds to fully germinate. However, some seeds may take longer, so patience is essential. Have you considered using a cannabis germination time lapse to monitor this process and see how the seed slowly transforms?
Can You Speed Up the Germination Process?
You can encourage faster cannabis seed germination by maintaining the right temperature (around 70-85°F) and keeping the seeds moist. Using a humidity dome or placing seeds in a glass of water for 24 hours before planting may help too. Just remember not to overwater.
When to Transplant Cannabis Seedlings?
Once the seedlings have developed a couple of sets of leaves, it’s time to transplant them into larger containers. This usually happens within 2-3 weeks of germination. If you delay the transplant, the plants may become root-bound, limiting their growth potential.
Cannabis Seedling Stage (2-3 Weeks)
After germination, cannabis enters the seedling stage. During this phase, the plant is growing rapidly and needs plenty of light and nutrients. A healthy cannabis seedling should have two sets of true leaves and a strong stem.
How long does the Cannabis Seedling stage last?
The seedling stage lasts about 2 to 3 weeks. During this time, the plant is establishing its root system and starting to develop its first real leaves. It’s important to monitor your seedlings carefully—too much water or insufficient light can stunt their growth.
What does a Healthy Cannabis Seedling look like?
A healthy seedling should have vibrant, green leaves, a sturdy stem, and visible root growth if you gently remove it from its pot. Yellow or curling leaves can indicate stress, often from overwatering, too much light, or nutrient deficiencies.
Cannabis Vegetative stage (3-15 Weeks)
Now we enter the vegetative stage, where cannabis plants focus on growing leaves and stems. During this stage, your cannabis plant is building the foundation for future buds, so it’s important to nurture it carefully.
How long should a Cannabis Plant Stay in Veg?
The vegetative stage typically lasts 3 to 15 weeks, depending on the desired size of your plant. Photoperiod plants need an 18/6 light schedule (18 hours of light, 6 hours of darkness), while auto-flowering strains will transition into flowering automatically, regardless of light hours.
How does a Healthy Cannabis Plant in Veg look like?
A healthy cannabis plant in the vegetative stage should have large, green leaves, a strong, thick stem, and a well-developed root system. If you’re seeing pale leaves, stunted growth, or yellowing, you may need to adjust your lighting, water, or nutrients.
Why does my Cannabis Plant want to Flower in the Vegetative Stage?
Sometimes, plants may begin to preflower earlier than expected, signaling a shift towards the flowering stage. This is often due to environmental stressors, such as light leaks or inconsistent temperature. Are you checking your plants regularly to catch any signs of early flowering?
Cannabis Flowering Stage (7-14 Weeks)
The flowering stage is when cannabis plants produce buds. This is the stage most growers eagerly anticipate, but it’s also the stage that requires the most attention to detail.
How to tell if a Cannabis Plant is ready to bloom?
A cannabis plant is ready to flower when it begins to develop preflowers, small, wispy structures that indicate whether your plant is male or female. Female plants will develop pistils (white hairs), while males will produce pollen sacs.
How long does It Take for Cannabis to Start Blooming after Switching the Light Cycle?
After changing the light cycle to 12/12 (12 hours of light, 12 hours of darkness), it typically takes 1-3 weeks for your cannabis plant to fully enter the flowering stage. During this time, you’ll see noticeable changes in the plant’s structure.
How Does a Healthy Cannabis Plant in Flowering Look Like?
During the flowering stage, a healthy cannabis plant will develop large, resin-covered buds. The leaves may begin to yellow and fall off as the plant focuses its energy on producing flowers. Have you been monitoring the color and structure of your buds to ensure they’re healthy?
How to Tell When Your Cannabis Buds Are Ready for Harvest?
Cannabis buds are ready for harvest when about 70-80% of the pistils have changed color from white to orange or brown, and the trichomes (resin glands) turn milky white or amber. Checking the trichomes through a magnifying glass or microscope can help you pinpoint the perfect time to harvest.
What to Do in Case of Early or Late Flowering?
Sometimes, cannabis plants may experience early flowering (premature flowering due to stress or light leaks) or late flowering (delayed blooming). Both can affect yield, so it’s crucial to maintain consistent conditions and troubleshoot any issues that arise.
Other important Cannabis life cycle considerations
Cannabis growth doesn’t stop at flowering—there are several other factors to consider throughout the plant’s life cycle.
What Stage of Growth does Cannabis Produce Trichomes?
Trichomes, the resin glands that produce cannabinoids and terpenes, begin to form during the vegetative stage but reach their peak during the flowering stage. These are critical for producing the potent and aromatic qualities we associate with cannabis.
How Long Should the Harvested Buds Be Left to Dry?
After harvesting, cannabis buds need to be dried for 7-14 days, depending on humidity levels. Proper drying helps preserve cannabinoids and terpenes, ensuring a better final product.
How Long Should the Harvested Buds Be Cured?
Once dried, buds should be cured in glass jars for 2-4 weeks to enhance flavor and potency. Curing helps improve the overall quality of your cannabis by allowing the remaining moisture to balance out and ensuring the buds burn smoothly.
How to Keep a Consistent Cannabis Growth Timeline?
One of the challenges in growing cannabis is maintaining a consistent timeline. This means carefully monitoring all stages, from germination to flowering, and ensuring the right growing conditions throughout. Keeping a growth journal or using a cannabis growth chart can help.
Understanding the Cannabis growth stages is key
