Seedlings also require proper watering, ensuring that the soil remains evenly moist but not saturated. It is important to gradually increase the intensity of light and adjust watering as the seedlings grow to promote healthy growth.
Vegetative Stage
Optimal Light Cycle
During the vegetative stage, cannabis plants require a specific light cycle to promote healthy growth. A commonly used light cycle is 18 hours of light followed by 6 hours of darkness. This extended light period allows the plant to focus on vegetative growth, including the development of leaves, stems, and roots. It is important to provide the appropriate intensity of light and maintain consistent lighting conditions to avoid stress or deficiencies.
Providing Adequate Nutrients
Proper nutrition is essential during the vegetative stage to support optimal plant growth. Cannabis plants require macronutrients, such as nitrogen, phosphorus, and potassium, as well as micronutrients, such as iron, calcium, and magnesium. It is important to provide a balanced fertilizer that contains these essential nutrients to prevent nutrient deficiencies or excesses, which can hinder growth and development.
Pruning and Training
Pruning and training techniques can be used during the vegetative stage to enhance plant structure, promote air circulation, and optimize light penetration. This can involve removing lower branches or leaves to redirect energy to the upper canopy, as well as using training methods such as topping or low-stress training (LST) to control plant height and promote lateral growth. Pruning and training help create a more robust and productive plant structure.
Flowering Stage
Switching Light Cycle to Induce Flowering
To initiate the flowering stage, cannabis plants require a change in the light cycle. Typically, growers switch to a 12/12 light cycle, providing 12 hours of light followed by 12 hours of uninterrupted darkness. This change in light cycle triggers hormonal changes in the plant, causing it to transition from vegetative growth to flower development. It is important to maintain consistent light cycles during the flowering stage to avoid stress or potential hermaphroditism.
Proper Lighting and Nutrient Management
During the flowering stage, cannabis plants require specific lighting conditions and nutrient management to support healthy flower development. High-intensity discharge (HID) lights, such as metal halide (MH) or high-pressure sodium (HPS) lamps, are commonly used to provide the necessary intensity and spectrum of light. Additionally, adjusting the nutrient ratios, particularly reducing nitrogen and increasing phosphorus and potassium, can encourage robust flower formation.
