Montmorillonite Clay

Adding Montmorillonite clay to soil can improve soil structure and drainage, while increasing water retention and providing essential trace minerals to plants. It also helps to buffer soil pH and reduce the effects of soil salinity. Furthermore, its anti-inflammatory and anti-bacterial properties can benefit the overall health of cannabis plants.

Montmorillonite clay is also pH neutral and inert, making it a perfect growing medium for hydroponic systems. When used in hydroponics, it improves nutrient uptake and provides a stable root environment for plants.

Note: Do not use on clay or other heavy soils.


– improves the wettability of soils
– improves soils water holding ability
– increases the CEC (cation exchange capacity) of soils
– prevents leaching of many nutrients
– makes nutrients from fertilizers or other sources more available to plants
