7 items left
  • 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 compressed coir block is suitable for a range of horticultural applications including:

    • General Purpose Potting - Simply mix through the supplied fertiliser and use as regular potting mix. The mix is lighter weight and has a higher water holding capacity than cheap bark based potting mixes available from supermarkets and hardware stores.
    • Seed Propagation - Ideal for achieving excellent germination results (due to high surface area of substrate), the foundation for high quality seedlings.
    • Cutting Propagation - Ideal for the 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 coir block is made of premium compressed coir with a very low salt index and natural nutritional content, including potassium and other essential nutrients. Coir is generally more suitable than common peat and pine-bark as coir based mix has a superior structure to common pine-bark based potting mixes and also produces better results for seed germination, as coir is lighter (enabling germinating seedlings to push through easier) has improved air-filled porosity and a lower EC.

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

    Fertiliser Option - EnduraMax™ TE Fertiliser

    Each compressed coir block is supplied with 50 grams of EnduraMAX TE slow release fertiliser which contains a range of essential plant nutrients including a full suite of important trace-elements. For seed propagation, this amount of fertiliser (50 grams) will be sufficient to get started, however if the coir mix is going to be used for general potting, upgrade the fertiliser to 200 grams, and if intended for repotting established plants, upgrade to the 400 grams.

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

This is the bomb!

I live in remote central Australia, not only is growing plants tricky but getting potting mix and maintaining water in pots is a task and a half. This stuff is amazing, holds moisture, fills the pot and the plants thrive. Love it!
