How many grams does an autoflower produce?

Sweet Seeds® autoflowering seeds have gained the trust of many cannabis growers for several reasons, including their magnificent flavor and aroma, powerful effects, impressive yields, and, above all, their fast and hassle-free growing process.

But how many grams does an autoflower produce? The yield of autoflowering plants typically ranges from 50 g to 250 g, depending on their genetics and the conditions in which the plants are grown. If you’re considering starting a grow with our autoflowering strains, you’re probably curious about the size of the harvest that you can expect.

So, in this article, we are going to show you how many grams of delicious buds autoflowering seeds can produce.

Conditions that Affect Autoflowering Growing

Let’s start by discussing some of the factors that can directly influence how many grams an autoflower produces.

Genetics

In terms of genetics, modern autoflowering cannabis seeds deliver much better results than the first generations. If you want to get the most out of each autoflowering seed in terms of yield, we advise that you take the time to carefully select the best genetics.

There is a wide variety of autoflowering genetics with Indica, Sativa, and hybrid tendencies, each of them totally capable of providing highly rewarding results in terms of yield. Our catalog includes an estimated production figure in the data sheet of each strain, based on optimal growing conditions. If yield is your top priority, check out our “XL Auto” autoflowering strains. Their larger size is a key factor that helps growers achieve the best and most abundant harvests in the global cannabis scene.

Fertilizer

Fertilizers play a vital role in the development and growth of your autoflowering cannabis plants, providing them with essential macronutrients and micronutrients for crucial processes like photosynthesis and protein synthesis.

Compared to photoperiod-dependent plants, autoflowering cannabis plants require less feeding due to their shorter life cycle. However, that doesn’t mean you can’t provide them with high doses of nutrients when needed, depending on their stage of development.

Sweet Seeds® autoflowering strains are well adapted to all types of grows, and their strong vigor allows them to process large doses of nutrients, as long as the levels remain within the limits that the cannabis plant can tolerate.

There are different types of nutrients available on the market, including mineral-based fertilizers, which are known for their fast and effective action on cannabis plants. However, it’s important to note that the excessive or improper use of these nutrients can lead to toxicity issues, causing salt buildup in the soil mix. This can negatively affect plant health, impacting both growth and yield. A good approach is to apply these fertilizers in slightly lower doses than those recommended by the manufacturers to avoid overfeeding the plant. Once you see that the plant responds well, you can gradually increase the dose of the fertilizer.

A valuable alternative is choosing organic growing techniques. These practices not only enhance the yield of autoflowering cannabis plants but also contribute to soil health and water conservation while being much more environmentally friendly. By adopting this approach, you create an ideal environment for plant development, leading to an outstanding harvest of high-quality buds and a lower risk of nutrient excess.

Another beneficial strategy is incorporating beneficial microbes into your plant’s feeding diet. These microorganisms improve nutrient absorption and protect plants from pathogenic organisms, optimizing both yield and overall plant health. This practice strengthens the symbiotic relationship between roots and soil microbes, leading to a more resilient and balanced root system, which ultimately results in higher-quality and more abundant buds.

Environment

If you’re growing indoors, you won’t have to worry as much about adverse outdoor weather conditions since you’ll be responsible for controlling every aspect of the grow environment. That’s why it is crucial to consider factors such as proper lighting (with the right spectrum and intensity) good ventilation in the grow room, and, most importantly, maintaining both temperature and humidity within optimal parameters to ensure your plants have the ideal environment for healthy development.

To achieve the perfect climate, you can rely on tools like heaters, exhaust fans, circulating fans, humidifiers, and dehumidifiers.

However, if you are growing outdoors, where the local climate plays a major role, make sure to plant at the most suitable time based on your region’s weather conditions. Ideally, you should start your grow in the months leading up to summer and continue until late in the season.

Pot Size

If you are not growing directly in the ground and you are using containers, the choice of pot size will depend entirely on your available grow space. This decision will directly impact the size of your plants and their final yield. As a general rule, the larger the pot, the greater the yield you can achieve.

For growing autoflowering cannabis seeds, pots larger than 20 liters are not necessary. Below is an approximate yield estimate based on pot sizes and its impact on how many grams autoflowering plants can produce in each scenario:

• 7 L pot: 40 to 50 g per plant indoors / 30 to 40 g per plant outdoors.
• 11 L pot: 50 to 70 g per plant indoors / 40 to 70 g per plant outdoors.
• 20 L pot: 70 to 180 g per plant indoors / 70 to 150 g per plant outdoors.

Keep in mind that these numbers are approximate and directly related to the growing method used in each occasion. It is also important to bear in mind that these estimates are based on optimal conditions. In some cases, even larger yields can be achieved with hydroponic growing systems.

Area

As mentioned earlier, pot size directly affects yield, and the choice of pot should align with the available grow space. If you have 1 m², you can fit, for example, 16 pots of 7 liters or 9 pots of 20 liters.

The higher the number of pots, the lower the yield per plant. Some home growers choose to grow a single plant that fills the entire grow area. To achieve this, advanced growing systems such as RDWC or aeroponics are recommended.

Climate

It’s essential to consider the climatic conditions to which your autoflowering cannabis plants will be exposed and maintain them within the optimal range, as this will determine their proper development and growth. Additionally, the growing location (whether indoors or outdoors) must be taken in consideration.

Growing Autoflowering Plants Outdoors

In outdoor grows, you won’t have control over lighting, temperature, or humidity. That’s why growing in warm, sunny climates offers more advantages compared to regions with less favorable weather conditions. However, other factors can still influence the final yield.

Try to position your plants facing south to ensure they receive at least 8 hours of direct sunlight per day throughout the entire grow cycle. Ideally, you should take advantage of the spring and summer months, allowing for multiple staggered harvests along the season. A common technique among home growers is to germinate a few seeds in mid-spring and then continuing germination more seeds each month until late summer. This way, the grower can achieve continuous harvests during the season, collecting mature flowers every month.

Growing Autoflowering Plants Indoors

Remember that autoflowering plants don’t rely on the photoperiod to flower. They bloom based on their age. However, you are still going to need to set the duration of the light cycle. We recommend keeping a schedule of 18 hours of light and 6 hours of darkness throughout the entire cycle, as this will result in a good harvest. That said, if you have the option and want to run a 24-hour light cycle, you can do so without issues. This can increase the yield of your autoflowering seeds, though it comes with the risk of stressing the plants, as they won’t have any dark period for recovery and essential physiological processes.

For indoor grows, it’s important to provide your plants with the right lighting. You can choose between different options such as LED, HPS, and LEC. The intensity and spectrum of each light source can significantly impact the final yield.

Lighting

The type of light you choose for your indoor grow is a key factor that will directly impact your harvest. This choice plays a crucial role in determining how many grams an autoflowering plant can produce, but it also influences the potency, flavor, and aroma of the buds.

There are multiple options available, but we recommend opting for either HID or LED lighting to maximize your yield. LED lights can help lower electricity costs while also improving the overall quality of the final product.

● HID Lights

HID lights are powerful and provide excellent light diffusion compared to other options. There are two main types of HID bulbs that deliver great results during different growth stages: MH (Metal Halide) for the vegetative stage and HPS (High-Pressure Sodium) for the flowering phase.

MH (metal halide) bulbs emit a blue light spectrum and are an ideal choice for plants in the growth phase. On the other hand, HPS (high pressure sodium) bulbs emit a red-light spectrum, which is best for the flowering phase.

As you can see, these bulbs are a great option. However, they consume a lot of energy, making them less cost-effective in the long run. While HID lights are more affordable to purchase upfront compared to LEDs, their higher electricity consumption can significantly increase energy costs over time.

● LED Lights

LED lights offer a light spectrum that can be adjusted with high precision, allowing you to provide your plants with exactly what they need at each stage of their life cycle. LED panels consume significantly less power than HID lamps and generate less heat, which helps maintain optimal temperatures in the grow space.

A common rule of thumb for autoflowering cannabis growing is that a yield of 1 gram per watt of light is a reasonable expectation. However, with LED lights, this number can be exceeded, and sometimes even doubled. Keep in mind that these estimates are based on ideal growing conditions where all parameters are optimized, allowing the plants to reach their full potential.

Pruning and Training: Shaping Your Autoflowering Plant

Keep in mind that autoflowering strains have a very short life cycle. This means that applying plant training techniques can potentially stress the plant, which may have a negative effect in your final yield.

Exposing your plants to excessive stress can negatively impact their development. However, if you still want to apply training methods to your autoflowering plants, it’s best to opt for low-impact techniques that can help in boosting production. For instance, Low-Stress Training (LST) is an excellent approach that can deliver highly satisfying results without overly stressing the plant.

How Many Grams Does an Autoflower Produce Outdoors?

If you’ve ever wondered how many grams an autoflower produces outdoors, it’s important to know that your final harvest will largely depend on the climate in your area and the space available for your autoflowering cannabis plants.

Since outdoor grows offer unlimited space, plants can spread out freely, often leading to a high bud yield. To maximize results, it’s advisable to prepare a high-quality soil mix and fill a large planting hole, allowing the roots to expand fully.

With an ideal climate and a suitable growing area, autoflowering strains grown outdoors can yield anywhere between 35 g and 250 g per plant. An impressive harvest in an unbeatable time frame.

How Many Grams Does an Autoflower Produce Indoors?

As mentioned before, growing cannabis indoors allows you to control all the environmental factors that influence plant development, ensuring an optimal setting for your grow.

However, if the grow space is too limited, plant growth and overall yield may be affected. In a well-optimized indoor setup, under ideal conditions, autoflowering strains can produce anywhere from 450 g to 650 g per square meter, depending on the genetics being grown.

Tips for Maximizing the Yield of Autoflowering Seeds

To add even more value to our article on how many grams does an autoflower produce, here are some extra tips that can help you achieve the highest possible yield when growing autoflowering seeds.

Training or Shaping Your Autoflowering Plants

Applying training techniques to your plants can make a significant difference in your final harvest.

Low-Stress Training (LST) is a great option for beginners growing autoflowering plants, since it is a gentle technique that does not harm the plants if done correctly. Researching and mastering this method can be very beneficial.

Another approach is the Sea of Green (SOG) method, which involves growing a larger number of smaller plants. This technique maximizes space and, as a result, increases the overall yield. It is particularly effective in small grow spaces. Due to their compact size and fast growth, autoflowering seeds are ideal candidates for this method.

The More Light, the Better

As mentioned earlier, if you are growing autoflowering strains indoors, the recommended light cycle is 18/6, meaning 18 hours of light and 6 hours of darkness. Some growers also opt for 24 hours of continuous light. The key to maximizing your autoflower harvest is to provide as many lumens as possible for as long as possible.

For outdoor autoflowering grows, your cannabis plants will rely on sunlight to get the lumens they need for proper development. Following the same principle, place your plants in the sunniest spot available.

Adding Support

Using stakes, bamboo canes, or plant supports helps keep your plants upright and capable of bearing the weight of the buds. This prevents the plant from bending or even breaking. With proper support, plants expend less energy on staying upright and can focus more on increasing bud production, to our delight.

Perpetual Harvest with Autoflowering Plants

Growing autoflowering cannabis seeds allows for fast harvests that can be repeated several times throughout the year.

Since autoflowering strains are not affected by light cycles, you can introduce new plants into the same grow space even before your current batch is finished. This creates a continuous cycle, also known as a perpetual grow.

For outdoor grows, during the growing season from spring to fall, it is best to germinate new seeds in stages. Starting a new batch each month, ensures a steady harvest throughout the season.
