What Constitutes Super Soil?
Super soil constitutes a meticulously crafted mixture enriched with vital nutrients and elements promoting proper aeration, which is subjected to an intensive composting period spanning no less than 30 days prior to utilization. This strategic incubation phase facilitates the proliferation and flourishing of soil microbiology, thereby initiating a sophisticated nutrient breakdown process, which subsequently ensures the safe assimilation by plants without the peril of nutrient burn.
Furthermore, a biologically vibrant super soil amalgamation of this nature can adeptly serve as the foundational element of a living soil recipe tailored for autoflowers; it is imperative to highlight that these soil categories bear distinct characteristics. This superior form of soil medium is frequently embraced within the realm of regenerative agriculture techniques, showcasing its pivotal role in fostering a thriving and sustainable growing environment.

A sophisticated formula for creating super soil tailored for autoflowers can be devised by integrating dry fertilizer amendments along with essential soil constituents into a foundational soil blend, procured from reputable sources such as local gardening centers, specialized grow stores or agricultural supply establishments. Notably, several grow shops offer a range of pre-composed soils, a segment of which indeed qualify as premium super soils. In the Willamette Valley, Oregon region, certain enterprises actively engage in the production of dedicated super soil blends, catering to the escalating demand.
Individuals venturing into cultivation utilizing super soil often enhance the mixture with the inclusion of mycorrhizae, a form of advantageous fungus synergistic with plant root systems. This addition is poised to significantly amplify the nutrient absorption capacity of cannabis plants, thereby fostering an accelerated growth trajectory and augmented biomass. Employing this augmented autoflower super soil, replete with optimal nutrient concentration and conducive aeration properties, stands as a vital prerequisite in realizing the fullest growth potential and yield outputs of your autoflower plant species.
How to create super soil for autoflower cannabis?

In my cultivation endeavors extending over a decade, I have meticulously refined a soil mixture recipe, augmenting it with diverse ingredients over the years. This formulation yields a substantial quantity of super soil, sufficient to sustain a home cultivator managing 2-4 plants per cycle for approximately six months. It is advisable to calculate and prepare diminished quantities based on your specific needs, ensuring accurate proportionate division of components.
Historically, my experimentation with various mixtures incorporated soil, coco fiber, and peat moss. However, I have reverted to utilizing solely packaged soil (I have found Black Gold to be particularly efficacious) as my fundamental mixture component. It is important to note that all nutrient quantifications mentioned in milliliters (ml) signify the requisite quantity of nutrients per one cubic foot (CF) of the mixture. Consequently, this formulation results in a total of 12 cubic feet of soil mixture. To illustrate, 120 ml of bat guano per 1 CF, multiplied by 12 CF, culminates in a total of 1,440 ml.
The ingredients requisite for this mixture are delineated as follows:
- 4 to 6 large packets of premium organic potting soil fortified with mycorrhizae (utilize 4 bags if each measures 1.5 cubic feet or 6 bags for 1 cubic foot measurement). In subsequent references, CF will denote cubic feet.
- Two packets of pure worm castings, each encompassing 1 cubic foot.
- One packet of superior quality compost, measuring between 1 and 1.5 cubic feet.
- Two cubic feet of a chosen aeration element, which could be rinsed perlite, rice hulls, pumice, or lava rock.
- Half a cubic foot of biochar to facilitate nutrient retention.
The subsequent additions are quantified in milliliters for every cubic foot of the mixture:
- ½ cup (120ml) flowering bat guano (rich in phosphorous)
- ½ cup (120ml) bat guano (rich in nitrogen)
- 1 cup (240ml) processed bone meal or fish bone meal (source of nitrogen and phosphorous)
- ½ cup (120ml) feather meal (source of nitrogen and enzymes)
- ¼ cup (60ml) ground rock phosphate (phosphorous supply)
- ⅛ cup (30ml) Epsom salts (providing magnesium and sulfur)
- ½ cup (120ml) Gypsum (source of calcium and sulfur)
- ½ cup (120ml) azomite (for trace minerals)
- ⅛ cup 30 ml granulated humic acid (to facilitate nutrient absorption)
- ½ cup (120ml) Neem cake (acts as an insect deterrent)
- 1 cup (240 ml) Oyster shell powder (a good source of calcium)
- ½ cup (120ml) Kelp meal (supplies potassium and trace minerals)
- (5 ml per liter of pot dimension) granulated mycorrhizae (to be used during planting)
Duration required: 14 days
Acquiring Your Ingredients
Procure all necessary components for your mix and assemble them in one location. It is strongly advised to don protective gear such as a respirator or a particulate mask during the mixing process to prevent inhalation of fine particles that may infiltrate your respiratory system. Moreover, to avert skin and hair contact with the particles, attire yourself in long-sleeved clothing, gloves, and a hat. For substantial mix quantities, install a scrubbing fan/filter combination to contain the generated dust, a concern that amplifies when conducted indoors. Employ a garden spray bottle with a capacity of 4 liters to mitigate dust generation and facilitate mix hydration.
Preparing Your Mixing Area
Select a pristine location, devoid of debris and shielded from wind gusts, for setting up your mixing station. Arrange a sizable tarp, a children’s pool, or an alternative receptacle (an 8’ x 10’ dimension is suggested as a minimum) either on the ground or on clean, solid flooring, like concrete. Initiate the process by spreading half of the purchased soil, and crumbling any lumps or compacted sections. Subsequently, dispense the perlite over the soil layer cautiously, owing to its dusty nature. Layer the worm castings and compost atop the perlite, followed by the remaining portion of the bagged soil. Integrate these primary components meticulously for a minimum duration of three minutes, utilizing hands initially before resorting to a method involving rolling the soil within the tarp.
Compounding Your Super Soil
Spread the premixed soil uniformly across the tarp, striving for an even layer. Sequentially disperse each fertilizer component over the soil heap, endeavoring to minimize dust production, though this may prove challenging. Dedicate at least five minutes to mixing the soil assiduously, employing a method that entails a detailed hand mix of every square foot of the tarp, followed by multiple rotations of the soil heap. This approach is favored as it facilitates a comprehensive visual assessment of the mixing progress, delineated by the disappearance of visible fertilizer layers within the mixture.
Preserving Your Formulated Soil
Post a fortnight, the majority of the composting process will have transpired, permitting the transfer of the mixture into a designated storage container or retaining it within the tarp for impending utilization. Inspect the soil for areas retaining heat and execute further mixing if necessary. Under no circumstance should soil exuding heat from ongoing composting be utilized, as it possesses the potential to scorch the plant roots.
What makes premium soil vital for autoflowering plants?
Embarking on the cultivation of cannabis necessitates initiating with premium quality soil. It’s implausible to anticipate exceptional growth and bloom production if the soil quality is compromised. Optimal soil for autoflowers substantially eases the cultivation process, sparing you both time and exertion, particularly during the flowering and maturation stages.
This advanced autoflower super soil formula is crafted to negate the necessity of anything beyond water post-plantation. This approach eradicates the dependency on liquid fertilizers and the need for additional labor, enabling you to concentrate on mastering your irrigation skills and honing your observational abilities regarding the plant’s behavior.
An adept cultivator is marked by their dedication to vigilance. It’s feasible to witness the daily evolution of the plants and addressing potential issues early on becomes considerably simpler. Whenever feasible, immerse yourself in moments of tranquillity and scrutiny within your garden. This practice serves as an excellent conduit to absorb the covert wisdom nature offers. Incorporating a few worms into each pot can also be a significant asset, facilitating a natural and vibrant ecosystem within your cultivation setup.
What quantity of super soil is required for successful autoflower cultivation?
Upon completion of the composting process, the autoflower soil mixture will retain a substantial potency, potentially causing adverse effects if exposed to intense direct light or utilized in settings with elevated temperatures. It is imperative to note that this mixture harbors a significant amount of energy stored within its nutrients, notably nitrogen (N), phosphorus (P), and potassium (K), which are also employed in the production of explosives.

Should you opt to initiate the germination process of seeds directly within the confines of the super soil, it is imperative to substantially mitigate the concentration of the mixture. I would ardently recommend amalgamating one portion of super soil with three portions of bagged soil to circumvent any potential nutrient-induced plant damage.
Exercise caution when utilizing a fully concentrated super soil mixture for the growth of autoflower cannabis. It is vital to acknowledge that there is scarcely an opportunity to recover from the adverse effects of nutrient burn damage, and certain cultivars may demonstrate a lesser resilience compared to others. You possess the straightforward alternative of tempering the mixture you have crafted with conventional bagged soil as required.
If your cultivation plan encompasses the utilization of a singular container throughout the entire autoflower cycle, initiate by designating the bottom one-third of the container to be filled with super soil. Subsequently, the central section should comprise a blend with a 1:1 ratio of super soil and standard bagged soil, and the uppermost section should consist primarily of bagged soil, flanked by a 50/50 diluted super soil at the peripheral regions of the container.
Prepare a diminutive cavity for seed transplantation at the core of your container. Typically, I employ my index finger to create a depression approximately up to the midpoint of its length before delicately placing the seed within. Following this, I carefully cover it with soil to seal the cavity. It’s vital to avoid situating the seeds too deep, shielding them from potential adverse conditions like excessive moisture or diminished oxygen levels, thereby facilitating a swifter emergence towards the light.
