There are several reasons a person may wish to grow autoflowering Cannabis at home, whether it be for taste, effect, medicinal value, or yield. The amount an autoflower can produce will be the difference between how full your curing jars get, and how successful you are as a grower.

Autoflowering cannabis yield from 50-250g, but that can be affected by genetics, conditions, and nutrients, our top tips will help you get the most out of your autos!

1. What Does "Yield" Mean?

Yield refers to the estimated amount of buds produced and can be measured as dry or wet weight but after you’ve harvested, trimmed, and dry your cannabis plants, that is the final amount of dried buds and the official yield.

 

How much do autoflowers yield: meaning

Yields can be measured as dry or wet weight but the official yields is the amount of buds after drying.
 

You will notice that seed banks will often display the yield in a square meter scenario, as opposed to the dried weight per plant. Not only can a figure such as "450-550gr/m2" be misleading, but there are also many variables that will play a factor in the outcome of this value, so how much weed does a plant yield?

2. Factors To Consider

The Weather

When growing autoflowering cultivars outdoors, the climate plays a massive role in the outcome of your yield. 

Outdoor growers depend on the seasons to be able to get good yields from autoflowers, this happens because autoflowering cannabis plants depend on the right temperature, humidity, and sunlight to thrive, and this will reflect on the quality and quantity of the buds you’ll harvest.

People who live in hot sunny climates will be able to grow an autoflower all year long with excellent results, but those who experience shorter summers with cold winters may not harvest as much as someone in a tropical climate, who can expect to grow multiple times per year with superb results.

Now, when growing indoors you don’t have to worry that much about the conditions because you are responsible for controlling every single aspect of the growing conditions, this can be a good thing for more experienced growers but if you’re new to growing indoors, it can be quite tricky if you don’t have access or can’t afford the right equipment.

As you may know, autoflowers need certain conditions in each stage of growth, but as a general guideline, you should keep the temperature between 18-24°C  and the humidity should be kept around 70% in the vegetative stage, gradually lowering it until you reach 60% near the pre-flowering stage.

Then, when your autoflowers are starting to form the buds, the humidity should be around 50%, reaching 40-45% at the end of the flowering stage.

Pot Size

Not everyone has the luxury of growing in a meter square grow space, and some must resort to a small, discreet autoflower count that can be kept on a balcony, terrace, or back garden.

Depending on where you’re growing your cannabis plants, you will have to choose either a bigger or a smaller pot and this will end up affecting how big your autoflower grows, and consequently, the yields.

For example, if you are growing a large-sized autoflower in 10-12 liter-sized pots, you will be able to harvest 50-150g per autoflower as long as the conditions are optimum, so if you prefer smaller autoflowers and use smaller pots, the yields will be decreased.

  • There is no need to grow an autoflower in pots bigger than 12 liters.
  • Sea of Green requires a smaller pot size of 5-7.5 liters.
  • Planting directly into the ground is also a good option.

Nutrients Used

Supplementing your autoflowers with a rich source of N-P-K (macronutrients) and trace elements (micronutrients) is certainly one way to enhance production. Investing in organic nutrients or a complete living soil will be advantageous, as long as you maintain the ideal watering ratio.

This is because organic nutrients work different from synthetic nutrients.

 

How much do autoflowers yield: nutrients

Both organic and synthetic nutrients feed your autoflower but work differently.
 

Organic feeding consists of maintaining a good soil with beneficial microorganisms that form a symbiotic relationship with your cannabis plant, this way the fungi feed on the sugars produced by plants while they break down nutrients and retain water in the rhizosphere which makes it easier for your autoflower to absorb nutrients and hydrate.

On the other side, synthetic nutrients consist of feeding the roots directly, this means that you don’t have to maintain a healthy soil because synthetic nutrients can actually kill the microorganisms present, so despite being easier to feed synthetic, it’s easier to overfeed and end up burning your plants.

If feeding with synthetic nutrients, then follow the recommended guidelines when making your nutrient solution.

  • You will want to feed your autoflower only plain water for the final 2 weeks, to allow the autoflower to flush.
  • Some cultivars will be able to uptake higher amounts of a nutrient solution than others.

Plant Count

Another thing that will affect your yield is the number of plants you have in your grow space, you have the option to grow a few large-sized autos, or many smaller ones packed together in a Sea of green, each have their own advantages and disadvantages. 

For example, if you’re growing in a 1m2 grow space you will have to choose between making the most of just one or two big autoflowers or grow up to 6 smaller autos, this is up to you, obviously.

It is always a good idea to know in advance if you can grow a Sea of Green, SCRoG, or prefer to let your autoflower to grow naturally. 

Sea of Green

If you are choosing to grow many small autoflowers packed closely together, then make sure the cultivar is well suited for that setup. You want to go for a shorter autoflower that grows relatively homogeneous, this way you can fit in between 6-10 autoflowers in a meter square, planting in 5-7.5 liter pots.

 

How much do autoflowers yield: sea of green

SoG allows you to grow a lot of smaller autoflowering plants, which can end up increasing the yields.

SCRoG

When growing in a SCRoG setup, you can go for whatever you want, obviously, you won’t be able to fit 20 autoflowers in 1m2 but because this technique consists of shaping your autoflower into a dense canopy, you can get away with growing from 2-5 autoflowers in 7-10 liter pots. As long as you’re filling your SCRoG net properly, you’ll get a nice dense canopy and great results.

Big-Sized Plants

For some, it can be more practical to grow 1-3 bigger-sized autos, and for this, we recommend using a pot size between 10-15 liters to allow your autoflowers to grow to their maximum, reaching up to 150cm in some cases.

Plant Training

When it comes to autoflowering cultivars, it is best to apply certain training techniques to different cultivars. This will encourage a much bigger and more productive harvest, exposing the autoflowers to more direct light and increasing yields further.

We only recommend plant training if you can benefit from that or if you’ve had experience before because you can end up stressing your autoflower and that will have the opposite results, less plant growth, and lower yields.

 

How much do autoflowers yield: lst

LST allows you to shape your autoflower into the desired structure without stressing it too much.
 

There are two types of plant training, LST and HST, both of them serve growers to help modify and shape the structure of an autoflower to either make the most out of the light fixture or control the size of the plants if you have a limited grow space.

Low-stress training (LST) basically consists of bending or tying down the branches without mutilating the plants, as the name says, it’s less likely to stress your autoflowers when compared to HST and it’s what its usually recommended for autoflowers but you can get away with HST if you know what you’re doing, have in mind that LST requires patience and more work when compared to HST because you are shaping your plants gently day by day.

 

How much do autoflowers yield: topping

Topping results in similar results but it can be too stressful for autoflowers.
 

High-stress training (HST) consists of mutilating your cannabis plants, either by topping, defoliating, or fimming, you will have the same results as when performing LST but you will have less work because once you’ve cut a part of your plant, the work is done.

  • Low-stress training means tying the highest parts of the plant down, to create an even-growing canopy of large-sized buds.
  • It is best to avoid any type of plant training after your autoflowers have started flowering.
  • Using a SCROG setup can increase yield and allow for a much more efficient growing space.

The Cultivar

If you’re a home grower and want to make the most out of each seed or if you’re a commercial grower and you prefer production before anything else, then finding the best genetics to aid in this job will give you the upper hand, obviously, growing the highest yielding autoflower is the way to go but there are basic things you should know.

There is a wide range of Indica and Sativa characteristics in hybrid autoflowering strains, with some being more rewarding than others when it comes to yield. 

 

How much do autoflowers yield: cultivar

Even if you have the best growing conditions, you should look for the best genetics that suits your growing condition.
 

Now, don’t think that Sativa-dominant hybrids always yield more than Indica-dominant, even though Sativas grow more and consequently yield more, Indicas produce denser buds that, even though it might seem they produce less, they can end up weighing more.

So have in mind that although you should choose your genetics-based on how much they yield (if you’re looking for high yields) you should choose a strain that better suits your growing style and your growing conditions.

Always keep in mind:

  • Some cultivars may take longer to flower and yield more than others.
  • Certain strains are better suited for cold and others for hot climates.

This autoflower offers a unique flavor of a creamy cheesecake thanks to the elaborate mix of sweet, earthy, and fruity tastes, and produces large-sized buds that boast different shades of green and magenta or pinkish hues.

The delicious terpene profile Wedding Cheesecake Auto offers comes with a pleasant upbeat effect with a deeply relaxing edge that is well suited for daytime use but due to the high THC content, we recommend beginner smokers be cautious because it can be overwhelming for some.

Grow tips

  • It’s a great strain to harvest multiple times per year outdoors, due to its high resistance.
  • Flushing is a must if you want to really feel the strong and delicious terpene profile Wedding Cheesecake Auto has to offer.
  • We recommend using 12L pots to let this beauty grow to its maximum and show its full potential.

4. Top Tips On How To Get Bigger Yields

1. Training your autoflowers is the best way to ensure the buds get enough light and airflow, when you open up the canopy, all the flowering sites will get direct sunlight, especially the lower flowering sites. This will not only improve the quality and quantity of your harvest but will also allow you to control the width and height of the autos.

2. The more sunlight your autoflower receives over their 9-10-week life cycle, the more buds they will produce. Planting towards the end of spring, early summer will often deliver the best results outdoors. If you’re growing indoors, you should provide at least 75w per plant and experiment trying different light cycles such as 18/6, 20/4, or 24/0 each one of them has its own pros and cons but most certainly, the light you provide to your autoflowers, the higher the yields.

3. Plant training is a great way to really maximize your growing space and produce a crop that is uniform and easy to maintain, and it’s how to get the best yield from cannabis plants.

4. Adding support early on using bamboo canes will ensure your plants can withstand the weight of the buds and allow the plants to grow really fat buds without the risk of snapping the branches.

5. Autoflowers make it easy to maintain a perpetual harvest, by growing a fast flowering cultivar you can keep harvesting every couple of weeks in the same grow tent and under the same light cycle. 

5. In Conclusion

There are many variables that should be considered when thinking about the best autoflower yield. Hitting the numbers that the seed banks suggest takes time and is only used as a guide. Having the ideal balance of lighting, cultivar, nutrients, plant training, climate, and location all play a role and should be planned out beforehand to give you the upper hand when planting outdoors.

It's essential you provide the best conditions if you want the best yields; Things such as temperature, humidity, airflow, and nutrients can and will affect how your autoflowers perform their basic processes such as transpiration and photosynthesis among others, so it's important you have the right equipment to check and adjust these factors.

Obviously, you can grow your autoflowers without worrying too. much about it but if you're looking to make the most out of every single seed and really take your harvest to the next level, so we strongly recommend getting at least the basic tools to be able to measure and adjust the temperature and humidity.

Good luck hitting those numbers and harvesting crops as often as possible, if you have tips for our fellow growers feel free to leave a comment in the comment section below!
