Description
Imagine a soil so rich, so perfectly balanced with organic nutrients, that your plants need nothing but water for their entire life cycle. That’s the promise of SubCool’s Super Soil — a legendary organic growing method developed by TGA SubCool himself and trusted by serious growers for over a decade. This 100-gallon recipe mix package includes every exact amendment, from the same brands SubCool used, pre-measured and ready to combine with your base soil. Set it up, let it cook for 6–10 weeks, and then grow the cleanest, most flavorful plants of your life.
Why SuperSoil – SubCool’s Super Soil 100 Gallon Recipe Mix Package
SubCool’s Super Soil isn’t just another soil amendment kit — it’s the original recipe, sourced directly from TGA SubCool, using the exact same brands and quantities he specified. Most organic soil kits use generic substitutes or approximated ratios. This package doesn’t. Every ingredient — from the high-phosphorus bat guano to the BioAg Ful-Humix humic concentrate — is the real thing, in the right amount, for a true 100-gallon batch of authentic Super Soil.
The Super Soil method works by front-loading all the organic nutrients your plants will ever need directly into the soil, then allowing 6–10 weeks of microbial activity to break those raw amendments down into plant-available forms. The result is a living, self-sustaining root zone that feeds your plants on demand — no nutrient mixing, no pH chasing, no feeding schedules. Just water. For growers who want maximum organic quality without the complexity of a liquid nutrient program, Super Soil is the gold standard.

- Cost-Effective Organic Growing – Delivers maximum plant-available organic nutrition at a cost comparable to synthetic nutrient programs, without the ongoing expense of bottled nutrients.
- Complete Amendment Package – Everything you need for a full 100-gallon batch is included — no hunting down individual ingredients or guessing quantities.
- Broad-Spectrum Mineral Nutrition – Azomite provides over 70 trace minerals and elements that support root growth, crop yield, and long-term soil health.
- pH Buffering Included – Garden lime and Ful-Humix work together to buffer soil pH and prevent nutrient lockout throughout the grow cycle.
Use Cases
- Cannabis Cultivation (Soil) – The original and most celebrated application for Super Soil — produces water-only organic cannabis grows with exceptional flavor, potency, and terpene expression.
- Fruit & Vegetable Gardens – Use Super Soil as the foundation for tomatoes, peppers, squash, and other heavy-feeding fruiting crops that benefit from rich, sustained organic nutrition.
- Raised Bed Gardening – Mix into raised bed soil to create a long-lasting, self-feeding organic growing environment for seasonal vegetable and herb production.
- Container Growing – Ideal for large container grows where a pre-amended, water-only soil eliminates the need for ongoing liquid feeding throughout the season.
- Organic Flower Production – Supports heavy-blooming ornamental and edible flowers with the phosphorus-rich amendments needed for dense, vibrant bloom development.
- Living Soil Builds – Use as the amendment foundation for building a long-term living soil system that can be top-dressed and reused across multiple grow cycles.
Directions for Use
- Gather 8 bags (1.5 cubic ft each) of high-quality organic potting soil containing coco fiber and mycorrhizae (sold separately).
- In a large mixing area (tarp, bin, or raised bed), combine all amendments from this package with the base soil according to the recipe below.
- Mix thoroughly until all amendments are evenly distributed throughout the soil.
- Moisten the mixture to approximately 50–60% moisture (damp but not saturated).
- Allow the amended soil to rest and “cook” for 6 to 10 weeks in a warm location, turning occasionally to promote even decomposition.
- After the cooking period, fill your containers or raised beds with the finished Super Soil.
- Plant your seedlings or transplants and water only — no additional nutrients required for the life of the plant.
- Pro Tip: For container grows, some growers use a “hot bottom, cool top” technique — filling the bottom two-thirds of the container with Super Soil and the top third with plain base soil to prevent seedling burn during early growth.

Frequently Asked Questions
What makes this different from other super soil kits?
This package uses the exact amendments and exact brands from TGA SubCool’s original recipe — given to us directly by SubCool himself. Many competing kits use generic substitutes or altered ratios. This is the authentic recipe, nothing more, nothing less.
Does this package include the base soil?
No. The base soil — 8 bags (1.5 cubic ft each) of high-quality organic potting soil with coco fiber and mycorrhizae — is sold separately. This package contains all the amendments needed to transform that base soil into finished Super Soil.
Why does the soil need to cook for 6–10 weeks?
The cooking period allows beneficial microorganisms to break down the raw organic amendments into plant-available nutrient forms. Skipping or shortening this step can result in nutrient burn or incomplete decomposition. The longer the cook time (up to 10 weeks), the more fully the amendments will have broken down and the more stable the finished soil will be.
Do I really only need to water after planting?
Yes — when properly prepared and cooked, Super Soil contains all the macro and micronutrients your plants need for their entire life cycle. No liquid nutrients, no pH adjustments, no feeding schedules. Simply water with clean, unchlorinated water and let the soil do the work.
Is Super Soil suitable for all plant types?
Super Soil was originally developed for cannabis cultivation but works exceptionally well for any heavy-feeding fruiting or flowering plant including tomatoes, peppers, squash, and ornamental flowers. It is best suited for container growing or raised beds where the amended soil can be contained and managed.
How should I store unused Super Soil or amendments?
Store unused amendments in a cool, dry location in sealed containers or bags. Finished Super Soil should be kept moist (not wet) and covered during the cooking period. Once cooked, it can be stored for several months in a covered container before use without significant loss of potency.

When you grow with SubCool’s Super Soil Recipe Mix your plants require WATER ONLY for their entire life cycle because you have taken the trouble of putting all of the organic nutrients into the potting soil. Using pure organic nutrients in their raw forms mixed into a soil base allowing them to begin the decomposition process of breaking down into plant usable forms by letting the mixture rest for 6 to 10 weeks.
This amendments package has the food and amendments for a batch of SuperSoil but does not come with the 8 (1.5CF) bags of high-quality base soil containing Coco Coir and mycorrhizae.
