What are Autoflower Cannabis Seeds and Their Growth Cycle

What is Autoflower Cannabis and Explanation of Their Growth Cycle

Automatic cannabis, is a type of cannabis that does not depend on light cycle to start to flower.

Instead, they starts blooming automatically after a certain period of time, Ruderalis genetics give these plants an internal clock that tells them when to flower. 

During the grow cycle, it goes through four stages: sprouting, seedling, vegetation, and blooming.

Each stage requires different care and attention to ensure the plant grows healthy and strong.

Characteristics

Characteristics Of Autoflower Cannabis Seed

These seeds have some unique characteristics that set them apart from regular seeds.

For one, they tend to be smaller in size but still pack a punch when it comes to yield.

They also have a shorter lifespan, autoflower seeds take usually from 8 to 12 weeks to mature.

This makes them a great easy to grow option for growers who want a quicker turnaround time.

Another important characteristic of these seeds is their ability to grow in different lights.

They don’t require a specific light to start flowering, unlike photoperiod plants.

Since they are naturally faster growers than photoperiod strains.

This means that they will mature more quickly then when you are growing feminized photoperiod cannabis.

Growing Autoflowers Guide: Weeks From Seed To Harvest Time

Autoflowers are a popular choice for both novice and experienced cannabis growers due to their rapid growth and ease of cultivation.

In this guide, we will take you through the various stages of auto growth, highlighting key milestones such as the 3 week old, 6 week old, 1 month old, and 2 month old.

Growing Autoflowers Guide Time From Seed To Harvest Seedling

Seeds Sprouting And Seedling Stage (1-2 weeks)

The journey begins with germinating your seeds.

Within 1-2 weeks, the seedlings will emerge and establish a solid root system.

During this time, it’s crucial to maintain optimal environmental conditions like temperature, humidity, and lighting to ensure healthy growth.

Vegetation Stage (2-4 weeks)

At the 3 week old autoflower growth stage, your plants will be in vegetation stage.

This is when they focus on developing a strong structure and foliage.

As your plants continue to grow, they will require more light, nutrients, and water to support their rapid development.

By the end of the vegetation stage, around the 1 month old mark, your plants will be ready for the next phase.

Flowering Phase (5-11 weeks)

During the blooming, your plants will start producing buds, and you will see significant changes in their appearance.

Week 5 is the beginning of this stage, and it is essential to adjust lights and nutrient ratios to promote bud development.

At autoflower week 6, the nugs will become more prominent, and the 6 week old autoflower plant will continue to grow taller.

As you reach week 7, you will notice the development and the distinct cannabis aroma.

Autoflower week 8 is when the plants begin to mature, and the nugs become denser.

At autoflower week 10, the trichomes will turn milky, indicating that the plants are nearing final stage.

Final Phase (12 week)

By autoflower week 12, your plants should be done.

Trichome’s will have reached their peak CBD potency, and the nugs will be fully developed.

To ensure a successful crops, monitor the trichome’s color and appearance closely, as this is a key indicator of when your plants are done.

Factors That Influence Reaping Time

Factors That Influence How Long Do Autoflowers Take From Seed To Harvest Time

There are many factors that can influence the average life cycle it takes for plants to mature.

Some of the most significant factors include genetics, environmental conditions, nutrients, and lightning.

Additionally, the quality of the soil, water, and nutrients the plant receives can also affect autoflowers grow rate and yield.

Genetics and Autoflowering Strain Selection

Genetics And Autoflowering Strain Selection

Choosing the right auto Indica and Sativa strain is crucial for maximizing growth rate and yield.

Factors such as growth speed, yield, and genetic resilience to environmental conditions and pests should be considered when selecting a strain.

This helps ensure healthy and robust plant growth.

These days, modern autoflowers can satisfy with CBD levels even the most demanding of users.

Recreational users won’t have difficulties finding automatic varieties rich in THC similar to photoperiod feminized seeds, and holistic users can get autoflowers low in THC levels but high in CBD to benefit from the non-psychoactive cannabinoid.

The Influence of Terpenes in Autoflowers Cannabis

Terpenoids in autos contribute to their flavor and aroma and can also affect their growth rate and yield.

Certain ones have antibacterial or antifungal properties that protect the plant through entire life cycle, while others help regulate growth rate for larger yields and better quality production.

Ideal Environment

Ideal Growing Autoflower Cannabis Plant Environment

To ensure healthy growth, auto plants need proper temperature, humidity, lighting, and air circulation.

During the vegetation stage, temperatures should be 70-85°F and humidity around 50-70%.

During blooming, lower temperature to 65-80°F and humidity to 40-50%.

Autoflower plants require 18 hours of light during vegetation stage and 12 hours during blooming, and LED lights are a popular choice for their energy-efficiency and full spectrum lighting.

Nutrient And Water Management

Nutrient And Water Management For Autoflowering Cannabis Strain

Proper nutrient and water management are crucial for growing healthy plants.

During the vegetation stage, provide higher nitrogen levels, and during the flowering stage, higher phosphorus and potassium levels.

Overwatering can lead to root rot and other issues, while underwatering can lead to stunted auto.

Organic nutrient solutions are a popular choice for healthier growth.

Typical Time Frame For Autoflowering Seeds

Typical Time Frame For Autoflowering Seeds Life Cycle And Development

During the first 2 weeks, the plant will go through the germination and seedling stage, where it will sprout its first set of leaves.

In the next two weeks, the plant will enter the vegetation stage and will continue to grow. 

In the week 5, plant will begin to bloom.

From the start of the blooming, it usually takes about 6-8 weeks for the buds to fully mature and be ready for reaping.

However, this can vary depending on the strain and the desired level of potency.

How Long Does it Take To Grow Autoflower Seed

To grow auto plant, start by germinating the seeds and transplanting them into nutrient-rich soil with proper lighting and watering.

Monitor nutrient and water intake and perform low-stress training during vegetation stage.

Adjust nutrients schedule during blooming.

They take around 8-12 weeks to producing beautiful crops depending on genetics and environmental conditions.

Germination of Autoflowering Cannabis Seeds

Germination of Autoflowering Cannabis Seeds

There are different methods for germinating auto seeds such as the paper towel and direct-to-soil method.

Keep seeds warm and moist to encourage sprouting.

After sprouting, transplant the seeds to nutrient-rich soil and provide proper lighting, nutrients, and water to help them grow healthy.

Seedling Stage

Seedling Stage

The seedling stage is critical to establish roots and develop their first leaves.

To ensure healthy growth, provide the right amount of light, humidity, and nutrients.

Avoid overwatering as the roots are still developing.

Many growers use high-intensity grow lights and humidifiers for the ideal growing environment.
