Advice from our specialist

For 'Young Plant' production, growers require a growing medium that is free of sticks and roots for automated filling of paper and fiber cells. The growing medium must be clean and free flowing to not clog machinery, but must provide good structure to encourage root development. PRO-MIX YP has been specifically formulated for this application.

  • SPHAGNUM PEAT MOSS (45-55%) ?

    Canadian Sphagnum peat moss is a natural, organic matter that comes from a peat bog. This primary resource is carefully harvested by vacuum harvesters. Peat moss comes in various fibrosity and levels of decomposition. Once carefully graded, peat moss assures that qualities of each grade are optimized for based on grower and uses for a final product reaching high quality requirements.


    Coir is a natural product which comes from the exterior envelop of an aged coco fruit. We have carefully selected a material providing the 3 important following qualities for a high-quality professional growing medium:

    • Physical (particles type and size)
    • Chemical (washed material with a very low salinity level)
    • Microbiological (exempt from any pathogens)

    Perlite is an alumino-silicate ore of volcanic origin. The raw ore is crushed, graded and screened in various particle sizes. Perlite has a high total-porosity and improves drainage and air porosity.


    Used to adjust pH to optimum range. Also a source of Calcium and Magnesium.


    A wetting agent is a substance that reduces the surface tension of water, allowing water to penetrate and uniformly wet growing media.


    Biostimulant is a strain of bacillus that naturally enhances growth and increases germination rates. It creates an optimized environment that promotes growth and reduces the impact of stresses on plants.
