Soma's Sacred Soil DIY Super Soil Mix - Organic Amendment for 50L

Soma's Sacred Soil DIY Super Soil Mix is a concentrated organic amendment blend that turns 50 litres of ordinary light potting soil into a fully amended, water-only living soil. Mix the bag through your soil, let it activate for two weeks, and you have a biologically active medium that carries plants through roughly 10 to 12 weeks of growth and flowering on water alone. It follows the same living soil principles as our ready-to-use Soma's Sacred Super Soil 50L, supplied as a concentrate so you can build the soil yourself, amend a mix you already trust, or bring last season's spent soil back to life at a lower cost per litre. Water only. No bottled nutrients. Once activated, the soil supplies its own nutrition for the full 10 to 12 week cycle. No feed charts, no EC chasing, no mixing bottles. Just water. Important: two week activation before planting This mix is a concentrate, not a ready-to-plant soil. It must be blended into 50L of light potting soil and left to activate for two weeks, kept slightly moist at room temperature, before anything goes into it. Planting straight into freshly mixed soil risks burning young roots. Specification Amends 50 Litres Of Light Potting Soil Product Type Organic Super Soil Amendment Concentrate Ready To Plant After Two Week Activation Additional Feeding Not Required Feed Duration Approx. 10 To 12 Weeks Fills 2 x 25L Pots Or 3 x 18L Pots Application Vegetables, Herbs, Flowering Plants Growing Style Indoor & Outdoor, Organic Water-Only Organic Yes Vegan No, Contains Blood Meal & Bone Meal Produced In The Netherlands How To Use Soma's Sacred Soil DIY Super Soil Mix Empty the entire bag into 50 litres of light potting soil. Mix thoroughly so the amendments are evenly distributed. A tarp, wheelbarrow or large tub works well. Lightly moisten the soil and leave it to activate for two weeks at room temperature. Keep it slightly damp throughout, never saturated. After two weeks, fill your pots and plant. Water as required for the rest of the cycle. No additional feeding needed. Reviving old soil: the same bag can be used to re-amend 50 litres of spent soil from a previous round. Break the old rootball up, mix the amendment through, and activate for two weeks exactly as you would with fresh soil. Technical Analysis Figures below are the manufacturer's published analysis for the activated soil. Measure Value NPK Available 1.3 - 0.42 - 3.5 pH 6.9 EC 1.9 mS/cm at 25°C Get More From Your Living Soil The DIY mix supplies the nutrition. These pair with it to build and maintain the biology that releases it. Add Ecothrive Biosys For Extra Microbial Biodiversity A living soil only performs as well as the biology inside it. Biosys introduces a broad spread of beneficial bacteria and fungi that colonise the root zone, speed up the breakdown of the organic amendments in this mix, and make those nutrients plant-available faster. Adding it at mixing stage gives the two week activation period a stronger biological head start. View Ecothrive Biosys Prefer It Ready Mixed? Soma's Sacred Super Soil 50L The same living soil approach supplied ready to plant, with no mixing and no activation wait. Fill your pots straight from the bag and water. Ideal if you would rather skip the two week preparation, or want to run the ready-made soil alongside a DIY batch. View Soma's Sacred Super Soil 50L Compost Tea Applied through the cycle, a compost tea keeps soil life active and feeds the microbial population that cycles nutrients to the roots. Used alongside this mix it helps maintain biological activity right through to the end of flowering.

About Soma's Sacred Soil Soma's Sacred Soil is built on decades of growing experience and natural farming principles, developed over 15 years of research and three years of testing and scaling before release. The line spans water-only super soil, compost teas, dry premixes and bulk ingredients, all aimed at growers who want to move away from bottle feeding and let soil biology do the work. The manufacturer states that the soil is formulated to meet strict testing standards, with heavy metals held in a form that is unavailable for plant uptake, so harvests remain clean regardless of the growing environment. Less bottle feeding. Less waste. Just water and let nature handle the rest. Frequently Asked Questions What is the difference between this and Soma's Sacred Super Soil 50L? This is a concentrated amendment mix that you blend into your own 50 litres of light potting soil and activate for two weeks. Soma's Sacred Super Soil 50L is the finished soil, supplied ready to plant with no mixing or waiting. The DIY mix works out cheaper per litre and lets you reuse soil you already have. Do I need to add any other nutrients? No. Once activated, the mix supplies the plant for approximately 10 to 12 weeks on water alone. Additives such as compost tea or a microbial inoculant like Ecothrive Biosys are optional and support soil biology rather than replace feeding. Can I plant into it straight away? No. The two week activation period is essential. It allows the microbial population to establish and begin breaking the amendments down into plant-available forms. Planting immediately into freshly mixed soil risks nutrient burn on young roots. What kind of soil should I mix it into? A light, low-nutrient potting soil. Avoid pre-charged or heavily fertilised soils, as the combined nutrient load can become too strong. Old soil from a previous round also works well once the rootball has been broken up. How many pots will one bag fill? One bag amends 50 litres of soil, which fills two 25 litre pots or three 18 litre pots. Can I use it in coco instead of soil? It is formulated for peat-based potting soil. Coco can be amended, but it holds fewer nutrients naturally and buffers pH differently, so pH and salt levels need watching more closely. Use pre-buffered coco and keep it consistently moist to maintain microbial activity. Is it suitable for outdoor growing? Yes. It performs well in indoor pots and in outdoor containers or beds, on vegetables, herbs and flowering plants alike. Is it vegan? No. The mix contains animal-derived fertilisers including blood meal and bone meal. Why Buy From The Hydro Bros?
