The Vegetative State of Cannabis Explained

The Vegetative State of Cannabis

A marijuana plant undergoes two different phases in its entire life: the vegetative and the blooming stage. When cannabis seedlings develop leaves and foliage, the vegetative stage commences. 

Your seeds must be inserted into a pot after the marijuana plant enters the vegetative stage to start the growth process. Ensure you have the proper information before you order cannabis seeds.  Continue to read this post ahead to learn more about the vegetative stage of cannabis. 


How Can You Define The Vegetative State Of Cannabis?

As stated above, as a cannabis seedling develop its leaves, it moves into the vegetative stage. The marijuana plant requires light, nutrients, and air to grow and survive. Newly formed roots search for nutrients and water in their growth substrate. Ensure that the substrate has ample holes for the passage of air. 


When Does The Vegetative State Of Cannabis Commence? 

Marijuana seeds germinate and grow into seedlings that emerge from the ground. These plants have spherical cotyledons that possess a short life. After the seedling is planted in the soil, it starts to grow leaves after a specific period. 

Over the next two to three weeks, cannabis seedlings will develop and produce a sizeable number of fan leaves, which are essential for photosynthesis. When this occurs, the vegetative process starts.

What Is The Duration Of The Vegetative State?

We can divide the vegetative state into different weeks:

Week 1-2

Marijuana plants grow rapidly in this stage. Growers must, therefore, continually analyze their setup and adjust as necessary. The feeding process is simple; however, growers must pay close attention to their irrigation plans.

Before watering again, let the top part of the soil dry off. If the top is close to a light source, burns can occur. The light source should be kept at a safe distance from the plant, at least 30cm away. Significant humidity is required during the vegetative state of cannabis. Moreover, you can periodically shut off the interior fans to improve the plant’s health and growth. 


Week 3-4

During the first month of the vegetative stage, sexing is crucial to prevent the male marijuana plant from pollinating the area. If the plant has resinous blooms, you must get rid of the males quickly. Female flowers that are pollinated will produce seeds and not resin. Following the germination stage, sexing is possible. Tiny flowers appear on the male and female plants to signal the mating period. Male plants produce spherical flowers, whereas female plants produce teardrop-shaped flora. 


Week 5-6

After a month or so, when your plant grows considerably, you need to enlarge the space or move it to another place. Ensure that the place offers sunlight or artificial light for the plant to blossom. Calculate the number of plants you have per square meter and shift them accordingly to ensure that this particular strain is kept out of harm’s way and gets the desired nutrients.


Week 7-8

Growers can start with the topping process when a plant entails 3-5 nodes. Through topping, cannabis growers can increase yields after the plant’s growth is over two months. You can boost the plant’s usage by promoting lateral growth and cutting the primary stem at the top. 


In addition, you can also split the stem in half if you remove the main stem’s tip using a pair of sterile scissors. When this technique is used repeatedly, additional bud sites may appear on the plant. This is why cannabis plants require a healing period after each topping; this lengthens the vegetative state of cannabis.


After 7-8 weeks

The plant’s size is directly related to the number of bud sites produced by larger plants instead of those made by smaller plants. As far as light intensity is concerned, the buds won’t develop properly. Throughout the latter vegetative state of cannabis, you can visualize a growing plant. Always keep in mind that the length of the cannabis crop depends on you.


What Are The Growing Techniques For The Vegetative State Of Cannabis?

In order to develop and grow, the cannabis plant must go through a vegetative phase. The plant growers must ensure that the plants are in their optimum conditions. A plant may generate more blooms if provided with adequate light, water, and nutrients and has more bud locations or nodes. 

Growers can plant and maintain small plants because of the training they receive. Apply it before the first blooms start to bud. Several crucial physiological processes occur during the vegetative stage. Remember that the leaves must function fully to convert light and CO2 into power. 

The plant’s root system is expanding, which helps it take in water and nutrients to ensure proper growth. The growth medium determines how much light intensity is required for the vegetative stage. Growers must maintain their precautions to prevent pests and illnesses from harming crops. After a proper vegetative stage, plants produce better yields and more flowers. 


How Does The Plant Shift From The Vegetative To The Flowering State?

How much time do plants require to convert from the vegetative stage to the flowering one? If your plant has been blooming for some time, you can assume it will double its size. Keep an eye on the initial indications of the flowering stage. To avoid having your marijuana plants overrun your grow area during the blooming stage, ensure that you stop the vegetative stage before the plant reaches the height you desire.


What Are Some Growing Needs For The Vegetative Stage?


The basic requirements for the marijuana plant in the vegetative state are:

  • Light
  • Growing medium
  • Pot size


To grow a plant indoors, the light period should be divided into eighteen hours of light and six hours of darkness. The vegetative state of cannabis may last for a long time in an indoor plantation. When natural light offers a lapse for greenhouse crops, you can use artificial lights for the remaining period. Side by side, complete darkness is also essential. 

The term “growing medium” refers to where the plant grows. In addition, it also links to the soil mixture, peat moss, and coco coir. A growing environment supports the plant, allows the respiration of roots, and holds nutrients and water for the plant. 

Aeration is essential for maintaining healthy roots. Adding minerals like vermiculite, perlite, or coco coir will allow roots to grow in the crevices between particles, preventing soil compaction. Every growing medium needs a different watering and fertilizer routine.

Cannabis adapts to its environment and can grow in virtually any container. The most popular sizes for indoor plants are 5 liters to 25-liter pots. However, watering and aeration frequency may concern volumes greater than 25 liters. If you need to water the plant regularly during the day, it may need a bigger area. One also needs to know the pot’s material along with the size and the growing medium.

How Much Water Does My Plant Need?

Providing water to the cannabis plant depends on several factors, including the pot size, the plant’s size and stage, the soil composition, humidity and temperature levels, minerals, etc. On average, the water requirement is 20% of the pot size with the soil and its organic components, such as peat moss, humus, perlite and coco. 

What Are The Nutrients That The Cannabis Plant Requires?


The primary nutrients present in the soil are nitrogen, phosphorus, and potassium. Depending on the plant’s stage, they are required in varying amounts throughout the entire plant cycle. 

Nitrogen is one of the key components during the vegetative state of cannabis; however, the levels of K and P are lower. These levels rise when the plant commences blooming while the nitrogen levels decrease. For the flowering and vegetative stages, particular fertilizers are available.

Phosphorus is another essential nutrient required by the cannabis plant in the vegetative stage. It is used for energy storage, root development, and transfer during the process of photosynthesis and bud formation. 

Potassium is one of the essential factors in plant metabolism as it increases resistance to drought. During the flowering phase, potassium is the key to bud forming, and it’s essential to add it during the vegetative stage to evade insufficiencies. 


Other Micro-Nutrients

A cannabis plant requires more secondary nutrients to develop properly. These are sulfur, calcium, and magnesium. The micro-nutrients are essential, but only in limited amounts. These are cobalt, silicon, copper, molybdenum, iron, chloride, manganese, boron, and others. Plants undergo growth issues if micro-nutrients are unavailable, even though they are only required at minimal levels and are crucial for plant metabolism. 


pH levels

Cannabis plants grow in a slightly acidic medium. You must keep the pH levels between 6 and 7 for optimum plant growth. Almost every nutrient is available within this range. Using water with low or high pH levels will lead to nutrient deficiencies that negatively affect the plant’s development. Or, if you see signs of yellow leaves, you need to check the pH of the water being used.
