Soil Testing

Plant substrate and soil can be one of the best available tools for making precise adjustments to your cultivation system to get improved results. We have expertise in soil testing and are developing protocols to help you understand and manage your substrate to maximize yields, control infestations, fight disease and cut costs.

  The acidity or basicity (pH) as well as the texture of soils influence the ability of plants to absorb nutrients. For example, micronutrients tend to be less available in high pH alkaline soils. Lime can be added to make soil less “sour” (acidic) by raising the pH (while also adding calcium and magnesium). The optimal acidity-basicity (pH) range of soils for plant growth is 6.0 to 6.5.


Productive soil can be influenced by many composition factors that can be better understood and managed. With soil test data growers can realize a better yield, control infestation, disease and costs.

Soil texture also influences nutrient and water retention in surface soil horizons where the roots and most of the plant’s biological activity takes place. Clay and organic soils offer better retention than sandy soils, which tend to leach water and nutrients into sub-surface horizons. The optimal composition of soil for plants is equal parts sand, silt, clay and organic matter. Some soils are more productive than others and commercial growers often use artificial or soilless mixes of peat, perlite and vermiculite as soil substitutes.
