Autoflower Seeds For Purchase

Autoflower seeds are a highly versatile crop that brings together easy management and fast growth, making them an ideal option for beginners. Before you dive into the cultivation journey, we highly recommend familiarizing yourself with our comprehensive grow guide. With autoflower cannabis seeds, cultivators stand to gain a tremendous potential harvest, abundant in cannabinoid-rich buds.

What Are Autoflower Seeds?

Autoflower seeds are a unique strain of cannabis seeds, capable of flowering autonomously with little reliance on external cultivation factors. These seeds have been engineered to such an extent that they effortlessly outstrip the light-cycle dependency that feminized seeds require to yield a bountiful harvest.

Available in various forms, autoflower seeds can be engineered to be THC-rich, CBD-dominant, or balanced in both. In addition, they can offer a broad spectrum of terpene profiles, further enhancing their appeal. Their robust nature and quick turnover time make these strains a popular choice amongst novice cultivators and those looking for a speedy yield.

To truly understand and appreciate the unique nature of this strain, one needs to delve into the cannabis growth cycle. Comprising two primary stages – the vegetative phase followed by the flowering phase – each of these stages necessitates the presence of specific factors to progress smoothly and transition accurately.

In the case of feminized strains, the flowering phase is dependent upon a lack of light, and these strains - often referred to as photoperiod cannabis strains - require a significant shift in the light cycle to trigger the flowering phase. This isn't applicable to autoflower strains. Their flowering is triggered by an internal biological clock rather than light dependence, highlighting a key differentiator of these strains.

Autoflowering characteristics can be traced back to the cannabis ruderalis subspecies. Indigenous to the cold climates of Central Asia, Eastern Europe, and Russia, this species developed the autoflowering trait as an adaptive response to survive in its harsh native environment. This inherent characteristic ensures that the plant completes its reproductive cycle before the onset of extremely cold temperatures. Researchers at Amsterdam Marijuana Seeds have drawn inspiration from this natural adaptation to design the rapid growth, high-yield autoflower seeds currently available to growers.

Characteristics Of Autoflower Seeds

Autoflower seeds present a number of distinctive features. While they bring a multitude of benefits to the table for cannabis cultivators, there are some characteristics that might be less favorable. Here are some of the key characteristics to consider:

Speedy life cycle: Autoflower strains are often ready for harvesting significantly earlier than their counterparts. The average plant reaches maturity within 8 – 10 weeks from seed to harvest.

Discreet cultivation: Their compact size makes these plants inconspicuous, allowing for indoor cultivation, even in living spaces.

Minimal light demands: Unlike other strains, autoflower seeds do not demand high light levels. Their unique advantage lies in their ability to self-pollinate and flower within a predefined time frame, regardless of external light stimuli.

Unparalleled resilience: Among cannabis strains, these are some of the most durable you can find. They can thrive under some of the harshest conditions, making them a preferred choice for novice growers still acquainting themselves with cannabis cultivation and its unique requirements.

Fewer nutrients required: Autoflower strains demonstrate excellent survival capabilities. They do not require intensive care or a strict routine to thrive. Their hardy nature allows them to survive in nearly all conditions.

However, every rose has its thorn. Autoflower species may yield less compared to feminized seed species. In addition, these strains are almost impossible to clone effectively, and if cloned, often yield disappointing results.

Who Are Autoflower Seeds Suitable For?

Autoflower seeds are the go-to choice for novice growers and home cultivators. Their independent nature means they do not necessitate any special equipment or strictly controlled environments to flourish. Their autoflowering trait makes them ideal for unobtrusive cultivation both indoors and outdoors.

How To Cultivate Autoflower Seeds

Autoflower seeds are incredibly adaptable and can thrive in just about any environment. While cultivating them indoors under controlled conditions can improve the yield and overall performance of the plant, it's not strictly necessary. For a comprehensive understanding, refer to our guide titled "How to Grow Autoflower Seeds".

Consider experimenting with the following highly recommended autoflower seed strains:

How to germinate autoflower seeds?

Follow the steps below to achieve successful germination:

  1. Moisten two paper towels and place your autoflower seeds on them.
  2. Fold the paper towel over the seeds and place it on a plate.
  3. Cover this arrangement with another plate.
  4. Store the plates in a warm, dark location.
  5. Check daily to ensure the paper towels retain their moisture.
  6. When the radicle root exceeds 1 cm, you've successfully germinated the seeds.

How to grow autoflower seeds outdoors?

  1. Germinate your autoflower seeds in their final growing container (ideally holding more than 10 liters).
  2. Position the container to receive a minimum of 8 hours of direct sunlight.
  3. Water your seedlings daily to ensure they remain properly hydrated.
  4. Feed your autoflower seeds using a slow-release approach.
  5. Around 12 weeks after germination, you should be ready to harvest your plant.

Autoflower seeds, with their hardy nature and rapid growth cycle, offer a multitude of benefits to cannabis cultivators. Ideal for beginners and those with limited space or resources, these resilient seeds take the guesswork out of growth light cycles, allowing for easier and more predictable cultivation.

It's crucial, however, to ensure optimal conditions for germination. While autoflower seeds are indeed versatile, they still require basic care to germinate successfully. The soil temperature, moisture levels, and aeration significantly impact the success rate of germination.

A soil temperature of around 25℃ is considered optimal for these seeds. It's also vital to maintain a balance in soil moisture levels - the soil should be damp but not waterlogged. Overwatering can hinder oxygen flow to the seeds and result in stunted growth or even seed decay. Aeration plays an equally crucial role in successful germination. It aids in preventing mold and fostering a healthier root system for the plant.

Once these conditions are met, you can expect the seed to germinate within one to three days. The key indicator of successful germination is the emergence of a small stem sprouting from the soil surface, signaling the beginning of a new growth phase.
