Do autoflowers continue to grow during flowering?

Autoflowering cannabis plants are becoming increasingly popular among growers and breeders, especially due to their ability to flower independently of light cycles. A frequently asked question is whether these plants continue to grow and optimize yield during the flowering phase.

Autoflowering cannabis seeds originate from a cross between Cannabis sativa, Cannabis indica and Cannabis ruderalis. The latter subspecies is characterized by its ability to flower independently of light cycles. This means that autoflowering plants automatically enter the flowering phase after a certain period of time, without requiring a change in light exposure.

In addition to the germination period, autoflower plants go through two phases of growth, each of which has specific characteristics.

• Vegetative phase: In the first few weeks after germination, autoflowering plants concentrate on growth in the vegetative phase. They develop leaves, strengthen their stems and build up a stable structure. Optimal light, nutrient and watering conditions are essential here.

• Transition to flowering: The flowering phase begins automatically after 3 to 4 weeks, regardless of the light cycle. The plants form inflorescences, which is why an appropriate supply of nutrients optimally supports flower formation.

Tip: Seed germinates but does not grow This can happen if there is insufficient moisture, temperature or oxygen supply. A lack of nutrients, poor genetics or the wrong substrate can also be causes.

The flowering phase of autoflowering plants is divided into different stages, each of which has specific growth characteristics.

• Stretching phase: At the beginning of flowering, autoflowering plants often grow rapidly in height and increase in size. This growth phase lasts one to two weeks and prepares them for flower formation. Sufficient space and stabilization are essential.

• Continued growth: Some varieties continue to show moderate growth after the stretching phase while developing flowers. This influences the plant size, but the focus is now on flower formation.

The growth of autoflowering plants during the flowering phase is determined by several factors.

• Genetics: The specific genetics of a strain largely determine the growth pattern during flowering. Some autoflowering strains with indica genetics tend to remain more compact, while those with sativa influences can grow taller. The choice of strain should therefore be adapted to the individual growing conditions and goals.

• Environmental conditions: Optimal conditions such as temperature, light and nutrient supply can promote or inhibit growth during flowering. A constant temperature between 20 and 25 degrees Celsius, sufficient lighting and a balanced supply of nutrients are crucial for the healthy growth of a cannabis plant. Care should also be taken to ensure adequate humidity to prevent mold growth.

Tip: The germination period for cannabis seeds usually varies between 24 and 72 hours. During this time, it is important to keep the seeds in a moist and warm environment to ensure successful germination.

Proper care is essential for autoflower cannabis to continue growing during the flowering phase.

• Nutrient management: In the flowering phase, autoflowering plants need more phosphorus and potassium instead of nitrogen. Special flowering fertilizers and an adapted dosage promote flower formation.

• Light management: Although no fixed light cycle is necessary, plants benefit from 18 to 20 hours of light a day. Even light distribution and the correct spacing of the lamps prevent burns and maximize growth and flower formation.

To further increase yields, additional techniques such as Low Stress Training (LST) can be applied. This method helps to bring the plant into a more uniform shape, resulting in better light distribution and encouraging the growth of multiple side branches. Super cropping, where the plant is gently pinched, can also promote growth by encouraging the plant to produce more flowers.

Choosing the right flowering fertilizer is crucial. These fertilizers contain more phosphorus and potassium, which stimulates flower formation. Make sure to gradually increase the amount of fertilizer to avoid over-fertilization and nutrient burn.

Another advantage of Autoflower is its versatility in the application of techniques such as ScrOG (Screen of Green). This involves stretching a net over the plants to ensure an even distribution of light and create a wider growing area. This method can be particularly helpful in small rooms.

Another useful method for maximizing the harvest is topping. This involves cutting off the main shoots of the plant to encourage the growth of side shoots and thus increase the number of inflorescences. This technique can be carried out in the early stages of vegetative growth.

Before you start growing, you should check the pH value of the soil or nutrient solution. An optimum pH value not only promotes growth, but also ensures that the plant can absorb the necessary nutrients efficiently.

Autoflowering cannabis continues to grow during flowering, especially in the stretching phase. Growth depends on the genetics and the environmental conditions. With optimal care, a suitable nutrient supply and good light management, flower development can be positively influenced.

Autoflowers are ideal for beginners and experienced growers, as they thrive independently of the light cycle and grow quickly. Anyone with limited space or looking for an uncomplicated cultivation method will find these plants a practical solution.

Another advantage of autoflowering plants is their resilience to external conditions. They require less attention compared to photoperiod strains and can thrive in moderate temperatures in smaller spaces or even outdoors without problems. Their adaptability to different climates makes them an excellent choice for growers working in less than ideal environments.

The use of CO2 enrichment is another method to optimize the growth and flowering of autoflowering plants. Increased CO2 levels in the air can speed up the photosynthesis process and therefore increase growth. Especially indoors, where the plants may have more controlled conditions, this can be a significant advantage.
