Advice from our specialist

In undisturbed field soils, nature provides beneficial microbes to convert nutrients and make them available for plants. However, almost all potting soils and mixes are void of beneficial microbes. With PRO-MIX PUR, growers and homeowners can add beneficial mycorrhizae to their plants at transplanting or after their plants have been potted. Mycorrhizae have been proven to promote plant growth by acquiring nutrients and water that plants cannot normally access alone. The benefit is that mycorrhizae attach to plant roots and remain with the plant for its entire lifetime.

  • MYCORRHIZAE - PTB297 TECHNOLOGY 80 viable spores/cc (150 viable spores/g) ?

    A Biological Growth Enhancer that increases the yield of flower, fruit and vegetable plants by extending the root system to acquire the most of available nutrients in the soil. Mycorrhizae also improve resistance to root diseases and stresses.


  • CLAY ?

    White clay (Kaolin) has a low shrink–swell capacity and a low cation-exchange capacity. It is a soft, earthy, usually white mineral produced by the chemical weathering of aluminium silicate minerals, such as feldspar.


    Diatomite is a chalk-like, siliceous sedimentary rock that is usually light in color and consists almost entirely of silica. The properties which make diatomite valuable include low bulk density, high porosity, high surface area, insulating properties, inertness, absorptive capacity and high silica content.
