Cannabis buds usually bulk up the most during the last weeks of the flowering phase. This critical period, generally the last 2-3 weeks before harvest, is when the plants concentrate most of their energy on flower development. It is essential to provide the right conditions of light, nutrients, and care to maximize the growth and size of the buds.
✅When Do Buds Grow the Most?
Understanding when and how cannabis buds grow the most can be the key to a bountiful and high-quality harvest. This article will delve into the factors that influence bud bulking, from growth phases to optimal cultivation practices.
Growth Phases of Buds
Vegetative Phase
- Duration: 4-8 weeks
- Focus: Development of the plant structure (stems and leaves).
During this phase, the cannabis plant focuses on vegetative growth, developing a strong root system and dense foliage. Although there is no bud formation, a robust plant at this stage will establish a solid foundation for successful flowering.
Pre-flowering Phase
- Duration: 1-2 weeks
- Focus: Transition from vegetative growth to flowering.
Here, the plant starts to show the first signs of sex and small pistils begin to appear. It is crucial to adjust the light cycle to 12/12 (12 hours of light and 12 hours of darkness) to induce flowering in photoperiod plants.
Early Flowering Phase
- Duration: 3-5 weeks
- Focus: Initial bud formation.
In this phase, buds begin to form and develop. The plant continues to grow in height and width, and the first clusters of flowers become visible. It is important to maintain a nutrient balance to support this growth.
Mid Flowering Phase
- Duration: 3-4 weeks
- Focus: Development and expansion of buds.
During this stage, buds begin to bulk up significantly. The plant redirects more energy towards flower and trichome production. Proper administration of flowering-specific nutrients (rich in phosphorus and potassium) is essential.
Late Flowering Phase
- Duration: 2-3 weeks
- Focus: Final bulking and maturation of buds.
This is the critical phase where buds bulk up the most. The plant concentrates all its energy on flower development and resin production. Slightly reducing nitrogen supply and increasing phosphorus and potassium can enhance bud growth.
Factors Influencing Bud Growth
Light
Light is one of the most important factors in cannabis cultivation. During the flowering phase, it is recommended to use full-spectrum lights or flowering-specific lights that mimic sunlight, providing between 600-1000 μmol/m²/s of PPFD.
Nutrients
An adequate nutrient program is crucial for bud bulking. During flowering, cannabis plants require high levels of phosphorus and potassium. A PK (phosphorus and potassium) supplement during the last weeks can help maximize bud size and density.
CO2
Carbon dioxide is ideal for bulking up cannabis buds. Naturally, the air usually has a CO2 concentration of about 350-400 PPM, but in indoor cannabis cultivation, an extra dose of carbon dioxide up to 1500 PPM can multiply the size and weight of the buds.
Watering
Proper watering is essential to avoid water stress and ensure that plants receive enough water to transport the necessary nutrients for growth. It is important not to overwater to avoid root problems.
Training and Pruning
Techniques such as LST (Low-Stress Training), topping, and selective pruning can help direct the plant’s energy towards the main buds, promoting more uniform and vigorous growth.
❤️Tips to Maximize Bud Growth
Climate Control
Maintaining an ideal temperature between 20-26°C (68-78°F) and a relative humidity of 40-50% during the flowering phase can significantly improve the quality and quantity of buds.
CO2 Supplements
Increasing CO2 levels in the grow room can enhance photosynthesis, leading to larger and denser buds.
Continuous Monitoring and Adjustments
It is essential to constantly monitor pH levels, EC (electrical conductivity), and adjust nutrients according to the plant’s specific needs during flowering.
Advanced Training Techniques
- ScrOG (Screen of Green): This technique helps maximize light exposure and can significantly increase yields.
- Selective Defoliation: Removing some large leaves can improve light penetration to the lower parts of the plant.
Use of Micronutrients
In addition to macronutrients, ensuring that plants receive enough micronutrients (calcium, magnesium, zinc, etc.) is vital for optimal bud development.
⚠️Common Problems and Solutions
Nutrient Deficiencies
Identifying and quickly correcting nutrient deficiencies can prevent production loss. Using an EC meter to ensure nutrient levels are adequate.
Pests and Diseases
Maintaining a clean environment and regularly monitoring plants for signs of pests and diseases. Using preventive methods such as essential oils and organic insecticides.
Temperature Stress
Avoiding extreme temperatures that can stress plants and negatively affect bud growth. Using fans and climate control systems to maintain optimal conditions.
🧐Final Stage: Preparation for Harvest
Flushing the Roots
Flushing the roots with pure water during the last two weeks before harvest can improve the flavor and quality of the final product.
Trichome Inspection
Using a magnifying glass or microscope to observe the trichomes. Buds are ready to harvest when most trichomes are milky with some amber.
Cutting and Drying
Harvesting at the right time and slowly drying the buds in a controlled environment can preserve terpenes and cannabinoids, resulting in a high-quality final product.
👾Bud Growth Chart as Cultivation Progresses
| Cultivation Phase | Bud Growth (%) |
|---|---|
| Vegetative Phase (0-4 weeks) | 0% |
| Pre-flowering Phase (5-6 weeks) | 5% |
| Early Flowering Phase (7-10 weeks) | 25% |
| Mid Flowering Phase (11-14 weeks) | 50% |
| Late Flowering Phase (15-17 weeks) | 100% |
This table illustrates how cannabis buds grow and develop throughout the different cultivation phases. As you can see, significant bud growth begins in the early flowering phase and reaches its peak in the late flowering phase, where buds bulk up and fully mature.

🎯Frequently Asked Questions about Bud Growth
When do buds grow the most?
Answer: Cannabis buds grow the most during the last weeks of the flowering phase, typically between weeks 6 and 8 for most strains. This period, known as the bulking phase, is when plants concentrate all their energy on developing and maturing flowers. Providing optimal conditions of light, nutrients, and watering during this phase is crucial to maximize bud size and density.
How to know when buds are mature?
Answer: Buds are mature when the trichomes, the small resin glands on the flowers, change color from clear to milky and then to amber. Using a magnifying glass or microscope to observe the trichomes is the best way to determine maturity. The pistils, the small hairs on the buds, should also have changed color from white to orange or brown. Additionally, mature buds will be dense and resinous to the touch.
How long do buds take to mature outdoors?
Answer: The time it takes for buds to mature outdoors varies depending on the strain and climatic conditions, but generally, cannabis plants grown outdoors take between 8 and 12 weeks from flowering to harvest. Indica strains tend to mature faster, in about 8 to 10 weeks, while sativas can take between 10 and 12 weeks or even longer. It is important to observe the specific conditions of the plant and monitor the trichomes to determine the optimal harvest time.
