  • Premium compressed coir that is a light-weight potting-mix substitute suitable for a range of uses around the garden including seed propagation, repotting or general purpose potting. With the simple addition of water and some light mixing in a wheelbarrow, each of these 4.5kg compressed coir blocks expand to produce up to 70L of premium coir mix.

    The mix produced by the Tropicoir® coir block is suitable for a many horticultural applications including:

    • General Purpose Potting - Simply use as the expanded coir peat as a regular potting mix. The mix is lighter weight (because it does not include sand) and has a higher water holding capacity than cheap bark based potting mixes available from supermarkets and hardware stores. Many nurseries incorporate coir peat into commercial potting mixes to improve substrate properties, including texture, CEC and AFP.
    • Seed Propagation - Coir peat is a great choice for achieving strong germination results (due to high surface area of substrate), the foundation for high quality seedlings. Depending on the plant variety being grown from seed, sand or GP vermiculite may also be incorporated into a suitable propagation mix.
    • Cutting Propagation - Ideal for vegetative propagation of many softwood plant varieties due to improved levels of near-stem water retention.
    • Other applications - Also suitable for many other horticultural applications including as an additive to many horticultural substrates.

    The Tropicoir® Precision coir block is made of finely screened coconut pith and then compressed to form a premium coir block with a naturally very low salt index and natural nutritional content, including potassium and other essential nutrients. Coir is generally lighter weight than common peat and pine-bark as coir based mix has a superior structure to common pine-bark based potting mixes and therefore produces superior results for seed germination, as coir is lighter (enabling germinating seedlings to push through easier) and has improved air-filled porosity and a lower EC.

    This Tropicoir® Precision compressed coir block is a professional grade product used widely by the nursery industry in Australia.

    Fertiliser Option - EnduraMax™ TE Fertiliser

    Whilst the compressed coir blocks contain natural nutrition, for best results we recommend the addition of EnduraMAX TE slow release fertiliser a premium controlled release fertiliser which contains a range of essential plant nutrients including a full suite of important trace-elements. If the coir mix is going to be used for seed propagation or general potting we recommend including the 200 grams per block fertiliser option.

    For the full nutritional analysis of EnduraMAX TE slow release fertiliser, please refer to the relevant image in the image gallery.
