KiS Organics Biochar Soil Mix

It means the soil is pre-loaded with enough organic nutrients and microbial life to support your plants from start to finish without needing bottled liquid fertilizers. You simply maintain consistent moisture levels, and the soil handles the feeding.

Yes, this mix is designed to be reused. Because it contains biochar and a robust microbial ecosystem, the soil structure actually improves over time, becoming a more permanent habitat for beneficial microbes with each cycle.

We recommend using a container that is at least 7 gallons. This volume ensures there is enough soil mass to maintain the biological activity and nutrient buffering capacity required for a true water-only cycle.

The 8% biochar content acts like a sponge, increasing the soil's cation exchange capacity (CEC). This allows the soil to hold onto nutrients and moisture more effectively, keeping them available in the root zone rather than letting them wash away.

No, this product is independently tested for heavy metals to ensure safety and quality. We prioritize clean inputs to ensure your growing medium is free from contaminants.

The soil is formulated to perform best at a moisture target of 80 mbar. While you don't need a tensiometer, aim to keep the soil consistently damp like a wrung-out sponge, avoiding both bone-dry conditions and oversaturation.
