Growth Stages and Light Cycles in Cannabis Cultivation
Process of planting, growing and harvesting cannabis.
Understanding the different stages of cannabis growth and their respective light cycle requirements is crucial for successful cultivation. This unit will delve into the three primary stages of cannabis growth: the seedling stage, the vegetative stage, and the flowering stage. We will also discuss how to transition plants from one stage to another and how to recognize signs of plant stress during these transitions.
Seedling Stage
The seedling stage is the initial phase of a cannabis plant's life cycle. During this stage, the plant develops its first set of leaves. The seedling stage typically lasts for about 2-3 weeks. Seedlings require a lot of light, and a light cycle of 18 hours of light and 6 hours of darkness (18/6) is recommended.
Vegetative Stage
Following the seedling stage is the vegetative stage. This is when the plant undergoes most of its growth. The plant's stem will grow thicker and taller, and it will develop new leaf nodes. This stage can last from 3 to 16 weeks, depending on the strain and the grower's preference. During the vegetative stage, a light cycle of 18/6 or 24/0 (continuous light) is recommended.
Flowering Stage
The flowering stage is the final phase of growth, where the plant produces buds. This stage typically lasts 8-11 weeks. During this stage, the light cycle should be adjusted to 12 hours of light and 12 hours of darkness (12/12). This mimics the natural light cycle of autumn, signaling to the plant that it's time to produce flowers.
Transitioning Between Stages
Transitioning plants from one stage to another requires careful attention. When transitioning from the vegetative to the flowering stage, it's important to gradually adjust the light cycle over a few days to avoid shocking the plant.
Recognizing Plant Stress
During transitions, plants may show signs of stress, such as yellowing leaves, drooping, or slowed growth. If you notice these signs, it's important to assess your light cycle, nutrient levels, and overall plant care practices to identify and address the cause of the stress.
In conclusion, understanding the growth stages and light cycles of cannabis is key to successful cultivation. By providing the appropriate light conditions for each stage, you can optimize your plant's growth and yield.
