Making super soil for autoflowers is an essential step in the process of growing brilliant weed. There are additional steps too, but the soil is quite literally the foundation of your weed growing efforts.
If you’re growing your marijuana, it’s crucial to stay one step ahead of commercial growers. Otherwise, you won’t be able to make a profit off the weed you sell. If you only want to use weed personally, you’ll still want to have the best results possible.

That’s where making super soil comes in. It’s challenging to find a good brand of soil on the market that you can trust. They all make many claims, but it’s difficult to justify spending your money to buy them without prior experience. If you make your own super soil, you can trust it because you created it.
Super soil is like normal soil, but better. We’ll share why that is in the next section, and then in the rest of the guide, we’ll take you through how to make it, why to make it, and how to use it once you’ve made it. We’ll also be suggesting some cannabis strains you can buy to grow in the soil you’ve made.
Once you’ve read the entire guide, you’ll be fully informed about how to make super soil for autoflowers, and you won’t need to worry about getting it wrong. Any common pitfalls will be known in advance, and you’ll have step-by-step guidance that you can follow when you decide to create super soil.
However, it’s worth emphasizing that you should test everything before you commit to it. Start with a small amount of super soil, and compare it to growing marijuana strains in ordinary soil. That way, you can judge the differences for yourself before investing more of your time and effort. Not all marijuana strains grow the same way, so you should pick seeds from the same strain for both soil types.

The Basics of Autoflower Soil
Super soil has its name because it’s better than ordinary soil, yet it’s something you can make at home without too much difficulty. Once you know enough about how to make it and why you should use it, you can start changing the recipe to suit the growing area you have and the strains you’d like to grow.
Once you’ve got the right recipe for your needs, you’ll be able to rely on your super soil to take away the burden of constantly feeding your marijuana plants. The roots will absorb the nutrients as they’re needed, and your weed plants will flourish. That way, you can get on with other priorities while the soil takes care of nourishing your weed.
If this makes you wonder how super soil works, then you might be thinking it contains artificial ingredients that could interfere with the taste or smell of your weed. Thankfully, this is not the case. Super soil is wholly organic, and there’s nothing to worry about in terms of its composition. It simply enriches the environment that your weed plants grow in by providing higher concentrations of nutrients.
The soil doesn’t eliminate the need to attend to your plants, as you’ll still have to provide them with light and water. But it makes the daily maintenance process quicker and more straightforward, which might be enough of a difference to persuade you to produce some super soil. Labor is one of the downsides of growing cannabis, and super soil eases it.
You’ll find some brands of soil claim to be super soil and have the same effects as the soil you make yourself, but you can’t be sure unless you pay for it and use it. Instead, you can get all the ingredients for super soil and use your own standards to create it. That’s what we recommend you do, even if you’re a beginner.

Should You Make Autoflower Soil?
Now that we’ve covered some of the information about what super soil is, we’re going to tell you whether you should make the best soil for autoflowering plants. We’ll make the case for it and give you an overview of the advantages and disadvantages. That way, you’ll be able to make up your mind without having to spend extra time researching.
Why Make The Best Soil for Autoflowers
Autoflower soil can provide a lot of benefits to marijuana growers and to the marijuana itself. These benefits aren’t so easy to achieve when you buy soil from a store, as its mass-produced. You can still use super soil from a store, but it won’t be as worthwhile as growing it to your standards.
Once you begin to grow cannabis using super soil, you’ll notice that maintenance gets much easier. We touched on this in the previous section, but you’ll be able to get by with only adding water. That’s a game-changer compared to what you’d need to do if you were using regular soil. It’s less decision-making for you to do while you’re focused on getting the best results from your weed and dealing with the other priorities in your life.
However, you’ll still have some responsibilities. Your plants can still suffer from a disease, and pests can get on them. You’ll have to look out for these by being familiar with common weed diseases and pests. But that’s why super soil is so helpful. You’ll have the time to do this if you’re not concerned as much about nutrients in the soil.
Once you’ve made enough super soil, you can also rely on it to help grow other plants, such as cannabis companion plants. That’s another topic that is beyond the scope of this guide, but if super soil can help your cannabis, then it’s obvious it can help other plants too. Plus, if you produce enough and store it in your garden, you won’t have to worry about traveling to the store to buy more nutrients or soil.
When you grow cannabis in super soil, you’ll find it’s likely to be healthier and give you a greater yield, so long as you’re focused on ensuring your plants have enough light and water.

The Benefits and Drawbacks of Autoflower Soil
The benefits of super soil are numerous, and we’ll go through them first. That way, you can have the good news first. There may be others we’ve not included, but we’ll focus on the most important benefits.
Pros:
- It’s very simple to get to grips with super soil
- The quality of super soil will be greater than its rivals
- Flushing your plants won’t be necessary with super soil
Your weed will be much higher in quality if the soil it’s grown in is already high-quality. That’s why we recommend using it. But not only that, but you’ll also find that your weed won’t need as many additional ingredients. Because of that, you won’t have to flush them either, which is even better.
Cons:
- It takes extra money to prepare and create super soil
- It uses up your time at the start of the growing process
- Your marijuana plants won’t grow as fast
The overall time it will take to grow marijuana with super soil is 4-8 weeks, so you’ll need to do some planning ahead to get a good result at the end. However, so long as you do this, it’s just a matter of persistence until your weed is ready to harvest.

Making the Best Soil for Autoflowering Plants
Now that we’ve covered plenty of information about the best soil for autoflowering cannabis, it’s worth sharing how to make super soil for autoflowers. It is somewhat of a learning curve, but it’s worth doing because you’ll gain a skill that’s good for life. You can make the super soil for yourself or others and use it for a wide range of plants.
Once you’re experienced enough, you can choose the ingredients you want to include. That way, your super soil might become even better than the super soil that others use. There are many ingredients that you can choose, and they include:
- Humic acid
- Worm castings
- Dolomite
- Bone meal
- Bat guano
- Rock phosphate
But starting off your super soil requires only three simple ingredients. These are vermiculite, peat moss, and compost. Most of your soil should be made of peat moss, followed by compost and then vermiculite. The ratio should be 3:2:1.
Once you’ve mixed all these ingredients in the given ratio, you’ll need to wait a week for composting to take effect. Make sure that your soil doesn’t dry out or become excessively waterlogged. After all this, you’ll need to put the soil in the sun for 4-8 weeks, and then it will be ready to use.

Adding Nutrients to the Best Soil for Autoflowers
Even though super soil has most of the nutrients required to stimulate healthy marijuana growth, you’ll still need to add some from time to time. That way, you’ll guarantee the best results.
You’ll also need to remember that autoflower seeds require a different nutrient profile than feminized seeds. Typically, this is good news because autoflower seeds don’t need as many nutrients. But it does make it easy to overfeed your plants, so it’s essential to watch out for that.
Nitrogen is one of the most important nutrients to keep an eye on. If there is too much of it, your weed can be harmed, so you should make sure not to overdo it. On the other hand, one thing you should add plenty of is mycorrhizal fungi. These encourage the roots of your weed to take in more nutrients, which stimulates your plant to grow and remain healthy.
The pH of your soil is also essential to focus on. A neutral pH or just below it is sufficient for weed to thrive, and if it goes too far towards the acidic or alkaline ends of the pH scale, your plants will not grow. You can use pine needles to make the pH less alkaline and dolomite to make it less acidic.
Germinating Seeds in the Best Soil for Autoflowers
Planting seeds inside the super soil might seem like the easiest part, but there are also some points to consider when you do this. You’ll want to maximize the chances that your seeds germinate. The best way to do that is to get your weed from an online seed bank that sells high-quality seeds. I Love Growing Marijuana does just that, and you can buy strains like these from them:
You can find plenty more on their website, but these are just a few of the top ones they have listed at the time of writing. Once you’ve ensured your seeds are as good as they can be, you’ll want to think about germinating them.
You can do this quite simply by using a jiffy pellet. Just add water, and leave them for a day, but make sure the water is distilled. That will ensure your seeds are ready for planting in the super soil after they show their first shoot.
When you do this, don’t bury the seed deep into the soil. Instead, place it just beneath the surface with its shoot pointing downwards. The super soil and your careful attention will take it from there.

How to Use the Best Soil for Autoflowering Cannabis
Like we mentioned earlier, you can rely on super soil from stores to plant your cannabis seeds in, but making your own gives you more flexibility. When it comes to using it, you must know what your super soil is made of first. In a store, you can read the ingredients list, and with your own, you’ll know already.
If you choose soil from a store, you should check the product reviews from customers to see how they’ve used it. By doing that, you’ll be able to see how they’re using the soil and whether it’s suitable for the purposes you intend it for. You can also make a judgment about whether the super oil will be more effective than ordinary soil.
Once you’ve done all this, you can consider how you’ll use the soil you’ve bought. You can store it until you need it, or you can start shoveling it out into your garden straight away. It depends on when you’re planning to grow weed. If you haven’t got your seeds yet, then it’s best to store them.
However, if you’re making your own super soil, the rules are a bit different. You can make it and start the process while you’re searching for the best seeds. That way, you’ll be making the best use of the time you’ll have. 4-8 weeks can pass fast, but it will feel slow if you’re simply waiting for your soil to be ready.
If you’re waiting to use it for weed, then you can use some of it for other plants in the meantime and see how they perform relative to plants grown in regular soil. That might give you an indicator of how well your weed plants will perform with the soil. Beyond all of this, using super soil is similar to using regular soil. You simply lay it out where needed and plant seeds in it.

How Much of the Best Soil for Autoflowering Plants is Needed?
If you’re going ahead with using super soil that you’ve bought or made yourself, then it’s essential to use it wisely. After all, it will take you a lot of time to buy or produce more. Autoflower seeds generally don’t require as much soil, so it depends on the amount of weed that you intend to grow.
If you’re planning to plant dozens of seeds, then you’ll need a lot of soil. Many gallons of it to fill many pots. If you’re only planning to plant a few marijuana seeds for personal use, then you won’t need so much. It’s important to decide upfront because it will dictate the amount of each super soil ingredient you buy if you’re growing your own. That means you could end up spending more money than you have to if you get the figures wrong.
A good rule of thumb is that anything over an ounce of weed will need a lot of soil, and anything under that amount will require less. If you’re a beginner, it’s best to start with fewer plants. Once you know how many plants you’d like to grow, you can begin preparing more soil and planting more seeds.
If you’re planning to use a considerable amount of soil, then you’ll want to ensure your grow room is very large or you’re growing outdoors. If you don’t do this, then you won’t have enough space for your ambitions.
The most precise information suggests that if you’re using super soil, you should place 250g of super soil among every 750g of regular soil. That’s because super soil can add too many nutrients to your weed. That also helps prevent root burn, which we’ll discuss below.

How to Make Super Soil for Autoflowers Without Root Burn
Root burn is a condition that happens to cannabis plants when an excess of nutrients overwhelms your weed plant. It might seem reasonable to give your cannabis plant large quantities of nutrients, but if you do, they won’t react well.
If you want to ensure root burn doesn’t happen to your plants, then you should follow all the steps we’ve provided in this guide. However, when you’re doing that, the soil should be unfertilized ordinary soil, and you should keep the seeds there for 2-3 weeks before transferring them to super soil.
There is another method you can use too. If you take a container you’re planning to use to grow weed in and fill it with super soil, you can then add a layer of regular soil to the top of it. That will ensure the weed is ready for the super soil when the roots have reached it.
Autoflower seeds are a little more flexible when it comes to avoiding root burn. You can take an empty pot and place it in the middle of a larger one. Then you can fill the large pot with super soil and remove the smaller pot at the end. Once you’ve done that, you can fill the remaining space with super soil.

Conclusion
Now that you’ve read the entire guide, you should be fully informed about all the relevant aspects of super soil. We’ve covered how you can make super soil, why you should make it, the pros and cons of doing so, germinating your seeds, adding nutrients to your soil, and suggested some strains you can buy.
You can find further information online if needed, but this guide should have given you enough to get started. You must take action and get started as soon as possible because time is of the essence when it comes to growing weed. It takes a long time once you’ve begun, and that will be even longer if you’re making super soil. In our judgment, it’s worth making super soil yourself, but you need to plan ahead to get the best results.
There are no guarantees that super soil will make your yields larger and the quality of your weed better, but if you use it alongside all the tips we’ve included in this guide, you should have a big chance of growing high-quality cannabis.
However, we also mentioned a selection of strains earlier, and they are a great selection, to begin with if you’re new to growing weed. That’s because autoflower seeds will flower automatically and require less maintenance. If you combine that advantage with the benefits of super soil, then your weed growing journey will be much easier.
But if you want to have the best possible chances of growing great weed, then there is one extra step you can take.
