Instead of tilling the soil between crops, organic matter is added on top, preserving the soil structure and microbial life. This approach enhances soil health and nutrient retention while reducing erosion and carbon emissions.

Each alternative growing method has its unique benefits and challenges. Choosing the right method depends on factors like grower experience, available resources, space constraints, and sustainability goals. Whether using hydroponics for precise control or living soil for natural and organic cultivation, these alternative methods offer exciting possibilities for cannabis growers seeking innovative and efficient approaches to cultivation.

The Growth Cycle of Cannabis

cannabis plants under grow lights

The growth cycle of cannabis, also known as its life cycle, consists of several distinct stages, each with its specific characteristics and requirements. Understanding the different phases of the growth cycle is essential for successful cannabis cultivation. Here’s an overview of the four main stages of the cannabis growth cycle:

1. Germination and Seedling Stage

Germination is the first stage, where the cannabis seed absorbs water, swells, and sprouts a taproot. The seedling emerges from the soil with a pair of embryonic leaves called cotyledons.

During this stage, the seedling is highly vulnerable, and care must be taken to provide the right conditions, including proper moisture, warmth, and light.

The seedling will develop its first sets of true leaves, and its roots will start spreading out and establishing themselves.

2. Vegetative Stage

The vegetative stage begins once the seedling has developed a few sets of true leaves and its root system is established.

During this stage, the focus is on vegetative growth, where the plant develops a strong structure, lush foliage, and increases in size.

Cannabis plants need plenty of light (usually 18-24 hours per day), appropriate nutrients, and proper pruning or training techniques to achieve a healthy and productive vegetative growth.

3. Flowering Stage

The flowering stage is initiated when the plant begins to receive longer uninterrupted periods of darkness, usually 12 hours of darkness and 12 hours of light (12/12 light cycle) or a variation to induce flowering.

During this stage, the plant transitions its focus from vegetative growth to the production of flowers (buds) that contain cannabinoids, terpenes, and other compounds.

The flowering stage typically lasts 8 to 12 weeks, depending on the strain and environmental conditions. The length of the flowering stage directly affects the final yield and potency of the harvested buds.

4. Harvest and Curing

Once the flowering stage is complete, it’s time to harvest the matured cannabis buds. Harvesting should be done when the trichomes (resin glands) on the buds are at their peak maturity, indicating the highest cannabinoid and terpene content.

After harvest, the buds undergo a curing process, where they are dried and cured in controlled conditions to improve flavor, aroma, and smoothness. Proper curing enhances the overall quality and potency of the final product.

It’s important to note that not all cannabis plants have the same growth cycle duration. Indica strains generally have shorter growth cycles, while Sativa strains tend to have longer ones. Additionally, autoflowering strains have a unique growth cycle as they automatically transition from the vegetative stage to the flowering stage based on age, not light exposure.

Understanding the growth cycle of cannabis allows growers to provide the appropriate care and environment at each stage, ensuring healthy, vigorous plants, and maximizing the quality and quantity of the final harvest.
