DIY Super Soil Recipe: A Step-by-Step Guide
What is the Super Soil Recipe?
Struggling to maintain a truly organic garden? It can be a challenge, which is why so many growers advocate for a great super soil recipe. This method is a fantastic way to achieve a heavy, abundant harvest with less guesswork. You're essentially creating a living, nutrient-rich foundation that feeds your plants exactly what they need, when they need it. It gives you complete control and sets the stage for incredible results from your crop.
So, What Is Super Soil?
A world-renowned grower, Subcool first developed the idea. It is a heavily amended soil that provides your plants with everything they require for super steady growth.
You need to mix the recipe precisely if you do, there will no longer be a need to provide your plants with "synthetic plant nutrients." Instead, you can occasionally add organic dry amendments during bloom and veg.
You can use Super soil for simplifying the process of growing, throwing plant feeding charts out of the equation, and mitigating the risks associated with overfeeding.
All you need to do is follow the recipe, monitor the pH levels, look for any insufficiencies, and resolve them accordingly.
Can You Reuse Your Super Soil?
Are you wondering what makes super soil so incredible? The soil is excellent because it can last you several years easily. In this process, the microbial life created keeps working its magic, allowing you to top-dress during flower or veg based on your needs.
Your first and foremost option is to follow the "no-till gardening method," allowing the soil to function independently without demanding any maintenance for years. Another benefit is that it can be re-amended after each growing cycle.
Why Your Plants Will Thank You
Switching to super soil isn't just about trying a new technique; it's about creating an environment where your plants can truly thrive. The benefits go far beyond just simplifying your routine. This living soil ecosystem works in harmony with your plants, providing them with exactly what they need, when they need it. The result is healthier, more resilient plants that produce higher-quality yields. Think of it as upgrading from a basic meal plan to a personal chef for your garden. Let's get into the specific ways this approach makes a noticeable difference in your grow room.
Enhanced Flavor and Aroma
One of the most celebrated benefits of using super soil is the remarkable improvement in the flavor and aroma of your harvest. The goal behind the original concept was to create a soil that brings out the very best in plants, much like how rich, fertile earth in a vegetable garden produces the most delicious produce. The diverse microbial life in super soil breaks down organic matter, making a wide spectrum of nutrients and minerals available to your plants. This complex nutrition allows them to fully express their genetic potential, resulting in more potent aromas and richer, more complex flavors in your herbs, fruits, and vegetables.
Simplified Nutrient Management
If you're tired of measuring and mixing liquid nutrients, super soil will feel like a breath of fresh air. The core principle is to create a soil mix so rich and complete that you only need to add plain water throughout the plant's entire life cycle. All the essential nutrients are already packed into the soil from the start, thanks to a carefully balanced recipe of amendments. This "set it and forget it" approach eliminates the need for complex feeding schedules and dramatically reduces the risk of nutrient burn from overfeeding. It simplifies your entire growing process, letting you focus more on your plants and less on mixing bottles.
My Go-To Super Soil Recipe
When you use the super soil recipe, there is no need for any synthetic liquid nutrients. The formula generates 100 gallons. Further, you can easily adjust the recipe to make Super soil as much as you need. If you're looking for amendments, you can find them here at Groindoors.com.
- 1."14 cu ft potting soil" when it comes to price, this does not need to be rich in nutrients or expensive. All you need is base soil, so there is no harm in getting something cheap. Whatever your plants need can be added as the process moves forward.
- 2."25-50 lbs. Worm Castings" an alternative would be to use half EWC and half compost.
- 3."5 lbs. Blood Meal" compared to others, this is a much faster nitrogen source and helps your plants grow bigger during the time of vegetation. (12-0-0)
- 4."5 lbs. Feather Meal" this is an extended and slow-releasing nitrogen source. It helps provide plants with an ample supply of nitrogen throughout life.
- 5."5 lbs. Bat Guano" This organic fertilizer is great for soil structure and improving absorption. It also ensures that your plants get a full micro and macronutrient profile.
- 6."2.5 lbs Bone Meal" This mainly is a fantastic source of calcium and phosphorus that can benefit the flowing process.
- 7."2.5 lbs Fish Bone Meal" If you are facing any issue with nearby dogs or bears, we highly recommend not using fish fertilizers. It will not benefit the flowing process; on the contrary, it will attract them to the plant. As an alternative, you can use bone meal and double the quantity.
- 8."3 cups Oyster Shell" This is a perfect choice if you are looking for a quality calcium source.
- 9."3 cups Kelp Meal" This substance has a perfect blend of micro-nutrients with a sufficient dose of potassium and nitrogen.

- 11." ¾ Cup Epsom Salt" this is a natural bloom blaster.
- 12."2 Tbsp Mycorrhizae" perfect for encouraging rapid rooting.
The Original SubCool Recipe
The recipe that started it all comes from the grower SubCool. The whole point of his super soil is to create a rich, living medium that provides everything your plants need from start to finish. Once you mix it, the idea is that you only need to add plain water throughout the entire growth cycle. To create the concentrate, you’ll mix a base soil with a powerful blend of amendments. The original recipe calls for 25 to 50 pounds of organic worm castings, 5 pounds of steamed bone meal, 5 pounds of high-phosphorus bat guano, 5 pounds of blood meal, 3 pounds of rock phosphate, and smaller amounts of Epsom salts, sweet lime, azomite, and powdered humic acid. It’s a serious mix for serious growers who want to go all-in on a water-only soil system.
A Simple Small-Batch Recipe
If making a massive batch of super soil feels a bit overwhelming, don't worry. You can easily scale things down. This popular small-batch recipe creates a potent concentrate that you can mix into your regular potting soil or coco coir. For a quarter-batch, you’ll need 12.5 pounds each of bone meal, blood meal, and bat guano. Then, add in 6 pounds of sulfate of potash, 3.75 pounds of dolomite lime, 2.5 pounds of Epsom salt, 2.5 pounds of azomite, and 1.25 pounds of humic acid. This scaled-down version is perfect for growers with limited space or those who want to test out super soil without committing to a huge volume. It still provides a fantastic range of nutrients to support vigorous plant growth.
A Critical Look at Super Soil Ingredients
The classic super soil recipe is a fantastic blueprint, but it's not the final word. As growers, we're always learning and refining our methods. Taking a closer look at each ingredient helps you understand its purpose, potential drawbacks, and how to get the most out of it. This isn't about reinventing the wheel, but about fine-tuning it to create the best possible growing media for your specific needs. Thinking critically about your inputs allows you to build a soil that is not only effective but also safe and sustainable for the long haul.
Heavy Metal Concerns
It’s important to know what’s in your soil amendments. Some common ingredients, particularly rock phosphate, can be sourced from deposits containing heavy metals like cadmium. Over time, these elements can build up in your soil and may be absorbed by your plants. If you are growing edible herbs or vegetables, this is a significant concern. Sourcing high-quality, tested nutrients and amendments from reputable suppliers helps you minimize this risk and gives you peace of mind about the purity of your final harvest.
Environmental and Ethical Considerations
The origin of your soil ingredients can be just as important as their nutritional content. For example, steamed bone meal is a direct byproduct of the industrial cattle industry, a fact that may not sit well with every grower's personal ethics. A great alternative is fish bone meal, which provides a similar phosphorus and calcium profile. It's often considered a more sustainable and safer option for organic gardens. Making these conscious swaps allows you to create a growing system that fully aligns with your values.
Maximizing Ingredient Effectiveness
Getting the best results from your amendments is all about proper application. Take mycorrhizae, for example. These beneficial fungi are incredible for root development, but they need to make direct contact with the roots to establish a relationship. Simply mixing them throughout a large batch of soil is inefficient and wastes a valuable product. The most effective method is to apply the mycorrhizae powder directly to the root ball of your plants during transplanting. This targeted approach ensures the fungi can colonize the root system immediately.
Long-Term Soil Balance
The ultimate goal of super soil is to create a self-sustaining ecosystem that feeds your plants for years. This requires balance. Some recipes call for several different high-phosphate ingredients, but a healthy soil with robust microbial life is very efficient at cycling nutrients. It doesn't necessarily need an excessive amount of any single element. Overloading the soil with too much phosphate can throw off the balance. A more measured approach often creates a more stable and resilient soil environment for the long term.
Safety First: Mixing Your Super Soil
Creating your own super soil is an incredibly satisfying project, but it can get messy. You'll be working with a variety of dry, dusty materials, from fine powders to coarser meals. When you start combining these ingredients, a lot of that dust can become airborne. Before you dive in, it's crucial to prioritize your personal safety. A few simple precautions will make the process clean, safe, and enjoyable, letting you focus on crafting the perfect home for your plants without any health worries.
Wear Protective Gear
When you're handling dry amendments, personal protective equipment (PPE) is non-negotiable. The fine particles in ingredients like bat guano, azomite, and kelp meal can easily irritate your eyes, skin, and respiratory system. Always wear a good-quality dust mask or respirator to avoid inhaling anything. Safety glasses will protect your eyes from stray dust, and gloves will keep your hands clean and prevent skin irritation. It's also wise to mix your soil in a well-ventilated space, like an open garage or outdoors, to help disperse the dust.
How to Make Your Own Super Soil
Before you start making your super soil, remember it's going to be very time-consuming and requires hard work so patience is key here. Once you have all the ingredients, you're going to have to mix everything for a while. Experts recommend letting everything compost for a while. Wondering why? Because it allows microbial life to take place.
Step 1: Combine Your Base Ingredients
Your first step requires laying down a kiddie pool or a tarp. Now you need to add half of the base in and spread out everything. Now add all of the other ingredients and Mix while moistening everything slightly.
Once everything is mixed, it is now time to add your soil's remainder into the mix.
Add more water to get the mix damp because water activates the process. Remember, the soil needs to be moist, not soaked ensure you don't overdo anything.
Sourcing Quality Ingredients
The success of your super soil recipe hinges on the quality of its components. When selecting your base soil, you don't need to break the bank on a nutrient-rich mix. The goal is to create a solid foundation with good structure and aeration. A simple, affordable potting soil works perfectly because you'll be adding all the necessary nutrients with your amendments. Think of it as a blank canvas. For the best structure, look for a balanced mix of one part peat, one part compost, and one part aeration material like perlite, which you can find in our collection of growing media.
Where you really want to focus on quality is with your amendments. These are the ingredients that will power your plants through their entire life cycle. High-quality worm castings, bat guano, and bone meal provide the rich profile of micro and macronutrients that makes super soil so effective. Sourcing potent, organic nutrients ensures your soil's microbial life will thrive. Speaking of which, always use non-chlorinated water when mixing and watering. Chlorine can harm the beneficial microbes you're working so hard to cultivate, and they are the key to making all the nutrients available for your plants.
Step 2: Let It "Cook" (The Composting Phase)
You must keep checking your soil over the subsequent few weeks and mixing everything until the additives are no longer noticeable.
Add the whole thing into different cans and buckets and get it damp. Most soil will allow the composting process to take place. For the upcoming few months, you must ensure the soil is moist. This process aims to make sure everything in the mix becomes usable for the plant to benefit from. Before you finally get to use it, give it one last mix.
How Long to Compost
Patience is a virtue, especially when it comes to super soil. This isn't a mix-and-go recipe; it needs time to "cook." Think of it like a slow-simmering stew where all the flavors meld together. You'll want to let your super soil compost for at least 30 to 60 days before using it. This waiting period is crucial because it gives the beneficial microbes time to break down all those rich, organic amendments you added. This process, known as curing, makes the nutrients bioavailable for your plants to absorb later. Rushing this step can lead to "hot" soil that might burn your plants, so give it the time it needs to mature into the nutrient-rich powerhouse it's meant to be.
Signs of Active Composting
During the composting phase, your soil will give you a few clues that it's working its magic. One of the most obvious signs is heat. If you stick your hand into the center of the pile, it should feel noticeably warm. This warmth is generated by the millions of microbes hard at work breaking down the organic matter. You'll also want to turn the pile every week or so to introduce oxygen and ensure everything composts evenly. As you mix, you'll notice the distinct textures of the amendments gradually disappearing, blending into a uniform, dark, and rich soil. Keeping an eye on the pile's temperature with simple environmental controls like a compost thermometer can help you track the progress of this living ecosystem.
Using Non-Chlorinated Water
When you moisten your super soil during the mixing and composting stages, the type of water you use matters immensely. Always use non-chlorinated water. Why? Because chlorine is designed to kill bacteria, and that includes the beneficial microbes you're trying to cultivate in your soil. Using chlorinated tap water can essentially sterilize your mix, undoing all your hard work. If tap water is your only option, you can easily dechlorinate it by letting it sit out in an open container for at least 24 hours, which allows the chlorine to evaporate. Alternatively, using a water filter or collected rainwater are great options to protect the delicate microbial life that makes your super soil so effective for your plants.
Step 3: Get Your Pots Ready for Planting
Now the super soil is ready to be used. However, you need a light soil blend to serve as a soil plug. This last-minute addition protects you from young plants from nutrient burns. All your plants will indeed develop a robust root system, which will later extend into super soil.
The Layering Technique
Once your super soil has finished "cooking," you can't just fill your pots to the top with this potent mixture. Instead, you'll use a simple layering method to create the perfect environment for your plants. Start by filling the bottom one-third to one-half of your final container with the super soil concentrate. Then, fill the rest of the pot with your plain base soil. This smart technique creates a safe, neutral zone for young roots to establish themselves. As your plant matures, its roots will naturally grow downward, tapping into the rich reservoir of nutrients in the super soil layer precisely when it's strong enough to handle them.
A Warning for Seedlings and Clones
Here’s a critical piece of advice: never plant your seedlings or new clones directly into the super soil concentrate. This mix is considered "hot," meaning it's so rich in amendments that it will overwhelm and burn the delicate, developing root systems of young plants. This nutrient burn can seriously stunt their growth or even be fatal. Always start your plants in the top layer of plain base growing media. This acts as a protective buffer, giving them the gentle start they need to build a strong foundation before they're ready to access the powerful nutrients below.
How to Water Plants in Super Soil
Now you already know that the plants will no longer be fed liquid nutrients; all you need to do now is water them regularly. Again, don't overdo it 'give the plant enough water to keep the medium wet.
An excellent way to check whether your plant needs watering is by testing the soil with your hands. You need to provide more water if the soil is completely dried up to the first fingernail. It is far preferable to submerge yourself than to create a runoff if this is your first time or you lack experience. Otherwise, the water will wash away some of the soil's nutrients.
Does pH Matter in Super Soil?
Growers who are used to liquid nutrients understand the value of pH monitoring.
In organic growing, maintaining pH doesn't require much work; however, it is still a good practice and needs to be on your daily checklist.
With the use of super soil, you have successfully created an organic ecosystem making it maintenance-free. However, on frequently using your soil pH meter you can track your soilâs health better.
When organic amendments are dry, correcting deficiencies, imbalances, and toxicities takes much longer this is why regular checking of soil is imperative.
To keep things easy and cost-effective, you can use vinegar and lemon to lower the pH level or increase the acidity. On the other hand, you can use baking soda or "TNB Naturals pH Up" to raise the pH level naturally.

Frequently Asked Questions
Do I really only need to add water after planting? For the most part, yes. The whole point of creating a super soil is to pack it with a diverse range of organic nutrients that microbes will break down over time, feeding your plants as they need it. This front-loading of nutrients eliminates the need for a complex liquid feeding schedule. However, it's always smart to observe your plants. Some heavy-feeding plants might benefit from a top-dressing of dry organic amendments during their flowering stage to give them an extra push.
Can I plant my seedlings directly into my fresh super soil? Absolutely not. Super soil is considered "hot," meaning it's so rich in nutrients that it will overwhelm and burn the delicate roots of a young seedling or clone. This is why the layering technique is so important. You should always plant your young plants into a top layer of plain, unamended base soil, which acts as a safe buffer zone. As the plant grows stronger, its roots will naturally reach down into the nutrient-dense super soil layer when it's ready.
Is it okay to substitute ingredients in the recipe? You can definitely make substitutions, but you should do so thoughtfully. The key is to understand the role each ingredient plays. For example, if you can't find blood meal, you can swap it for another high-nitrogen source. If you have ethical concerns about bone meal, fish bone meal is an excellent alternative that provides similar nutrients. The goal is to maintain a good balance of nitrogen, phosphorus, and potassium, along with a wide array of micronutrients, so try to replace ingredients with something that serves a similar purpose.
How do I reuse my super soil for the next grow cycle? One of the best things about super soil is that it gets better with time. To reuse it, start by removing the main root ball from the previous plant, but don't worry about getting every little root out. Then, you can re-amend the soil to replenish the nutrients that were used. A simple way to do this is by mixing in some fresh worm castings or compost and a quality all-purpose dry organic amendment blend. After mixing, let the soil sit for a couple of weeks before using it again.
Why does the soil need to "cook" for so long? The "cooking" or composting phase is probably the most critical step. This period allows the millions of beneficial microbes in the soil to start breaking down all the raw amendments you added. This process makes the nutrients bioavailable, meaning they are converted into a form your plants can actually absorb. Rushing this step can result in a soil that is too "hot" and can burn your plants, so giving it at least a month to mature is essential for success.
Key Takeaways
- Create a self-feeding garden foundation: Super soil is a rich, living medium that you prepare in advance, providing everything your plants need for their entire life cycle. This method eliminates the need for complicated liquid nutrient schedules, letting you focus on watering.
- Allow time for composting and layer your pots correctly: Your super soil mix needs to "cook" for at least 30 to 60 days, which allows microbes to make the nutrients available. When planting, fill the bottom of your pot with super soil and the top with a plain base soil to protect young roots.
- Source quality ingredients and mix them safely: The success of your soil depends on potent, well-sourced amendments. When combining these dry ingredients, always wear a dust mask and gloves to protect yourself from inhaling fine particles.
