ABOUT THIS ITEM

Product Details

  • Six manageable portions — The pack contains six 650g bricks, each producing approximately 10 litres after hydration. Prepare the number you need and keep the remaining bricks dry.

  • Washed coconut coir — Made from coconut husk and washed to reduce soluble salts. Washing is a different process from buffering; choose the preparation your growing system requires.

  • Mix for your plants — Use as a component in suitable pot, basket or raised-bed mixes. Add coarser coir chips or other components when the planting needs a more open structure.

  • Hydrate before planting — Place each brick in a tub with room to expand. Add water gradually, following the pack directions, then loosen thoroughly until moisture and texture are even.

  • Add a suitable feeding plan — Coir is a growing-medium base, not a complete fertiliser programme. Match the feed to your plants and stage of growth, following the fertiliser label.

  • Store the rest for later — Keep unused bricks dry and sheltered until your next project. Once hydrated, protect unused coir from contamination and move it in manageable portions.

THE MATERIAL BEHIND THE PRODUCT

Thoughtfully made. Simply prepared.

From a few patio pots to a larger planting project, prepare your coir a brick at a time. The six-brick format lets you choose how much to hydrate without opening up the whole pack.

Each dry brick weighs 650g and produces approximately 10 litres of loosened coir. Store unused bricks away from moisture, and prepare the hydrated material close to where you intend to plant.

PRACTICAL PREPARATION

Handling & storage

Substrate Science

Fine coir particles hold moisture, while spaces between particles contribute to air movement after drainage. How you pack, blend and water the medium changes the conditions around the roots.

Washing reduces soluble salts but is not the same as calcium buffering. Match your feeding programme to the crop and water supply. Add coarser components where a more open structure is needed.

  • Moisture retention

    Fine coir holds water within the growing mix.

  • Adjust the structure

    Coarser components can change pore space and drainage.

  • Feed for the crop

    Match nutrition to the plant and water supply.

Product FAQ

Do I have to hydrate all six bricks?

No. Hydrate one or more bricks as required and keep the unused bricks dry. Each brick produces approximately 10 litres of loosened coir.

How much does the whole pack make?

The six bricks produce approximately 60 litres in total. Final volume depends on hydration and how thoroughly you loosen the material.

Are these bricks the same as buffered coir?

Washing and buffering are different treatments. These bricks are sold as washed coir. If your system requires calcium-buffered coir, choose a product specified for that purpose.

Do I need to feed my plants?

Yes, plan suitable nutrition. Coir provides the growing-medium base; use a feed matched to your plant and growth stage, following the fertiliser instructions.

Can I use coir chips in the mix?

Coir chips can help create a more open structure when used in a suitable blend. Choose the balance around the plant, pot size and watering regime rather than a universal ratio.

Can children use the bricks for a school project?

They can be used for supervised planting activities. An adult should manage preparation, water and tools. Keep work surfaces stable, avoid breathing dust and wash hands after handling growing media.
