What are autoflower seeds?
Autoflower cannabis seeds are a unique strain of cannabis seeds that can flower without high dependence on external cultivation factors. In addition, we have engineered AMS autoflower seeds to be rugged and self-reliant, so much so that they do not need the light cycle that photoperiod cannabis seeds require to yield.
There are many autoflower cannabis varieties; they can be high in CBD, high in THC, or a balance of both with a richly diverse range of terpene profiles. The autoflowering strains are the go-to genetics for beginner growers and those looking for a fast return..
So, what makes auto flower seeds strains unique?
To understand the uniqueness of autoflowering weed seeds, we would take a closer look at the cannabis growth cycle.
The average growth cycle of the cannabis plant consists of two (2) distinct phases; the vegetative phase and the flowering phase. The vegetative phase is the first phase, and the flowering stage is the next, and each step requires some factors to be in place for them to occur and transition accurately.
In the flowering phase, light (rather the absence of light) is critical for this strain to flower. As opposed to autoflower seeds strains, these strains are referred to as photoperiod cannabis strains as they require a shift in the light cycle to trigger flowering. But the same cannot be said for the autoflowering seeds strains. The flowering of the autoflower seed is not light-dependent. It does not rely on external cues to flower or produce buds; instead, it works around its time clock.
The autoflower genetic trait was first discovered in the Cannabis Ruderalis autoflowering subspecies.
The Ruderalis species developed the autoflower trait through environmental adaptation and as a survival mechanism. Originally an indigenous plant of the cold regions of Central Asia, Eastern Europe, and Russia, the Ruderalis autoflowering cannabis species adapted to the cold and often harsh environments of its indigenous locale by developing an autoflower weed gene that ensures that reproduction occurs before the temperature plummets. That gene is carried by all autoflower seeds.
Based on this natural adaptation, our breeders at Amsterdam Marijuana Seeds have designed autoflower seeds that enjoy speedy growth and a great yield.
For whom are Autoflower cannabis seeds?
Autoflower cannabis seeds are the preferred option for beginner growers and those who cultivate their cannabis. Because of the nature of the plant, it does not require any special rig or controlled environment to perform optimally and yield.
The autoflowering nature of the plant allows for single-growth and private farming indoors and outdoors.
How are autoflower seeds created?
Autoflower cannabis seeds are created by crossbreeding cannabis ruderalis with other cannabis strains. The Cannabis ruderalis is a hardy, fast-flowering cannabis that originates in Central and Eastern Europe. By crossbreeding ruderalis with different strains, breeders create autoflower seeds that retain the best traits of both parent plants. The resulting plants are typically small and compact, with a short flowering period, now referred as autoflowers
Characteristics of autoflower Seeds
The autoflower seeds are characterized by several features. While the strain possesses many benefits for cannabis growers, some factors are not as endearing.
We have listed some of the main advantages of this strain below;
On the flip side, autoflower seeds species has a few thumbs down.
- Possibly lower yield: Autoflowers are always crossed with a Ruderalis plant which does not grow big. So they may sometimes produce less yield than the feminized seeds species.
- Poor-quality clones: These strains practically cannot be cloned. And if they ever are cloned, they often perform very poorly.
How potent are autoflower cannabis seeds?
Autoflowers generally have the same potency variations as the other species. There are a few autoflower cannabis seeds strains that stand out as being particularly potent. One such autoflower is the White Widow XTRM Autoflower Seeds. This strain is known for its high THC content, up to 23%. White Widow Autoflower Seeds Strain is also known for its high yield, making it a popular choice for growers.
Another strong autoflower seeds strain is our Forest Fruits Autoflower Cannabis Seeds this strain has a THC content of up to 23%, and it produces large, dense buds that are covered in trichomes. Being a mix of the very potent New York Diesel and Blueberry 420 known for its sweet blueberry flavor, which makes it a popular choice for smokers who enjoy flavored strains.
What do you need to Grow autoflower weed seeds?
You need a growing medium, water, light, and nutrients to grow auto-flower weed seeds. A growing medium is any material that can support plant growth; the most common growing medium is soil, but other options are coco coir, Rock wool, and vermiculite. Water is necessary for all plants to grow, water them regularly. Light is also essential for plant growth; auto-flowering weed seeds must be exposed to light for 12 to 18 hours daily.

Semantics Explained: What are autoflowers, autoflowering, auto flower seeds?
The answer is easy, they are all the same thing! Auto flower seeds, or autoflowering cannabis plants, represent a revolution in the world of cannabis cultivation. Unlike traditional strains, autoflower cannabis seeds don't rely on light cycles to flower. Instead, they transition based on age. This unique trait comes from the Ruderalis genetics present in autoflower seeds. As a result, autoflower marijuana plants are often faster and more compact, making them ideal for both novice and experienced growers.
Autoflower Seeds vs. Feminized Seeds
Autoflower seeds and feminized seeds represent two distinct categories in the world of cannabis cultivation, each with its unique characteristics and advantages. Autoflower seeds, as the name suggests, automatically transition from the vegetative phase to the flowering phase without the need for a change in light cycle. This trait makes them more resilient and faster to harvest, often preferred by beginners or those looking for a quick yield. On the other hand, feminized seeds are bred to produce only female plants, eliminating the risk of male plants that don't produce consumable buds. Feminized seeds may offer higher yields and allow for more control over the growth process but require careful monitoring of light cycles to induce flowering. In summary, while autoflower seeds provide ease and speed, feminized seeds offer precision and potentially larger yields, making the choice between them dependent on the grower's goals, experience, and preferences.
Genetic Traits: How do the genes of autoflower seeds work for autoflowering?
Autoflower seeds carry the genetics of Cannabis ruderalis, a variety native to regions with short summers. This genetic background allows autoflower seeds to bloom without depending on light cycles. When you purchase autoflowering seeds from AMS reputable autoflower seed bank, you're getting a blend of Ruderalis autoflower strains with other popular strains, ensuring the benefits of autoflowering cannabis while retaining potency and flavor.
No difference for Autoflowers: How to germinate the autoflower seeds?
Starting with autoflower seeds begins with the germination process, a crucial step in cultivating healthy autoflower cannabis plants. Germination is the process where the autoflower seed breaks open, and the taproot emerges, signaling the beginning of growth. To germinate autoflower seeds, you can use the paper towel method, where you place the seeds between moist paper towels and then inside a sealed plastic bag or container. Keep the environment warm and humid, around 70-80°F (21-27°C). Within a few days, you should see the taproots emerging. Once they do, carefully transplant the germinated autoflower seeds into your chosen growing medium, whether soil or hydroponic system. Ensure that the taproot faces downward and is covered lightly with soil. Proper germination sets the stage for robust growth, so handle the autoflowering seeds with care and provide them with the right conditions to thrive. Source your autoflower seeds from AMS autoflower seed bank to ensure quality and genetic integrity.
Autoflowers are non-photoperiod: autoflower seeds vs photoperiod seeds
While both autoflower seeds and photoperiod strain plants can produce high-quality cannabis, their growth patterns differ. Autoflowers, stemming from autoflower seeds, transition to the flowering stage based on age, not light exposure. This means autoflower cannabis can be harvested faster than photoperiod strains. For those looking for a quicker yield, autoflower seeds are a way to go.
Starting with autoflower seeds is best for beginners!
For those new to the world of cannabis cultivation, starting with autoflower seeds can be a wise choice. Autoflowering seeds, due to their Ruderalis genetics, are often more resilient and require less maintenance. When purchasing autoflower weed seeds, also referred to as autoflower marijuana seeds, you avoid the hassle of manipulating photoperiod with light switching.
Indoor Growing Basics: Setting Up Your First Autoflower Garden
Growing autoflowers indoors offers control over the environment. Start by selecting high-quality autoflowering cannabis seeds. Ensure you have adequate lighting, as autoflower cannabis plants still require light to produce robust yields. With the right setup, even beginners can achieve bountiful harvests from their autoflower seeds.
Autoflowers outdoors are ok with cold and short season
Autoflowers are versatile, thriving both indoors and out. When planting autoflowering seeds outdoors, consider the climate. Autoflower weed seeds, due to their Ruderalis genetics, can handle cooler temperatures and shorter seasons. This resilience makes autoflower marijuana an excellent choice for diverse environments.
Watering and Nutrition: Simple Guidelines for Autoflowers
While autoflowers are generally low-maintenance, proper watering and nutrition are crucial. Autoflower cannabis plants, stemming from autoflower seeds, often have a shorter growth cycle, meaning they'll require specific nutrients at precise times. Ensure you're feeding your autoflowering plants appropriately to maximize yields.
Lighting Essentials: Understanding the Needs of Auto flower Plants
Despite not relying on light cycles to flower, autoflower cannabis plants still require adequate light for growth. When cultivating from autoflowering seeds indoors, ensure you provide enough light for vegetative growth and flowering. Quality lighting can significantly impact the yield and potency of your autoflower weed seeds' produce.
Pruning and Training: Gentle Care for Autoflower Cannabis Plants
Autoflowers, due to their compact nature, often require minimal pruning. However, some light training can maximize light exposure and yield. When cultivating autoflower cannabis from autoflower seeds, gentle care can lead to bountiful results.
Harvesting Your Autoflowering Plants: Timing and Techniques
Knowing when to harvest is crucial for maximizing the potency of autoflower marijuana. Unlike photoperiod plants, autoflowers have a set life cycle. Monitor trichomes and plant color to determine the best harvest time for your autoflower cannabis plants grown from autoflower seeds.
