Our soil, which was developed with Dalhousie University, contains only sustainable and regenerative ingredients, and with only natural ingredients found in nature. Our soil is also full of micro-organisms for full mineralizaton that then grows plants that are nutrient dense with absorbable nutrients to the human body. No other soil on the market tests for this nor can claim absorption rates as tinySoil.
The only thing, beyond taste, that matters is, does the soil grow plants that are healthy for you!
So the soil is completely pure of any synthetics and other chemicals.
