Mastering the Cannabis Flowering Stage: Tips and Tricks from Growers Choice Seeds

The cannabis flowering stage is a crucial period in the life cycle of your cannabis plants. It is during this stage that your plants transition from the vegetative phase to the production of beautiful, resinous buds. To help you achieve optimal results during the flowering stage, the experts at Growers Choice Seeds have compiled a comprehensive guide with valuable tips and tricks. Whether you are a seasoned grower or just starting out, this article will provide you with the knowledge you need to master the cannabis flowering stage.

Understanding the Cannabis Flowering Stage

The cannabis flowering stage is initiated by changes in the light cycle. When the hours of darkness exceed a certain threshold (usually 12 hours of uninterrupted darkness), cannabis plants will begin to transition into the flowering stage. During this phase, the plants redirect their energy towards reproductive growth, focusing on the development of flowers or buds.

It is important to note that different cannabis strains have varying flowering times. Some strains may start flowering earlier, while others may take longer. Understanding the specific characteristics of your chosen strain will help you plan and optimize your growing process.

Creating the Ideal Environment

Creating the ideal environment for your cannabis plants during the flowering stage is crucial for achieving healthy and abundant yields. Here are some key factors to consider:
Light: During the flowering stage, cannabis plants require a specific light schedule. Most growers opt for a 12/12 light cycle, which means providing 12 hours of uninterrupted darkness followed by 12 hours of intense light. High-quality grow lights, such as LED or HPS, are recommended for optimal bud development.

Temperature and Humidity: Maintaining the right temperature and humidity levels is essential for bud formation. Aim for a temperature range of 68-78°F (20-26°C) during the day and slightly cooler temperatures at night. Keep the humidity levels between 40-50% to prevent mold and mildew growth.

Air Circulation: Good air circulation is vital to prevent stagnant air and promote healthy growth. Use fans or ventilation systems to ensure proper airflow and reduce the risk of pests and diseases.

Nutrients and Feeding

Proper nutrition is crucial for healthy bud development during the flowering stage. Here are some tips for feeding your cannabis plants:

Transition to Flowering Nutrients: As your plants enter the flowering stage, they require a different nutrient balance. Switch from nitrogen-rich vegetative nutrients to phosphorus and potassium-rich bloom nutrients. These nutrients promote flower production and enhance bud density.
Follow a Feeding Schedule: Use a reputable cannabis-specific nutrient line and follow the manufacturer’s feeding schedule. Pay attention to the recommended dosage and adjust as needed based on your plants’ response.

Flush Before Harvest: Towards the end of the flowering stage, it is important to flush your plants to remove any excess nutrients and enhance the flavor and smoothness of the final product. Flushing involves using plain, pH-balanced water for the last week or two before harvest.
Managing Light Stress and Light Leaks

During the flowering stage, light stress and light leaks can negatively impact bud development. Here’s how to manage them:

Light Stress: Excessive light during the dark period can disrupt the flowering process and cause hermaphroditism (the development of both male and female flowers). Ensure that your grow space is light-tight by sealing any light leaks and avoiding interruptions during the dark period.
Light Leaks: Even small amounts of light leakage can interrupt the plant’s photoperiod and affect bud production. Inspect your grow area for any potential light leaks and use light-blocking materials to eliminate them.


The cannabis flowering stage is a critical period that requires careful attention and proper care. By understanding the specific needs of your plants, creating an ideal environment, providing the right nutrients, and managing light stress and leaks, you can ensure successful bud development and achieve impressive yields. Remember to choose high-quality cannabis seeds from trusted sources like Growers Choice Seeds to start your journey on the right foot. Happy growing!
