Plan around your pots
Choose plants suited to your available light and container space. Check how much growing medium your pots need before preparing a batch. Use containers with suitable drainage and protect indoor surfaces from water.

OUR COMMITMENT TO INCLUSIVE GARDENING
Small-space growing
At Coirology, we believe a small home should still have room for growing. Compact 650g bricks let you prepare a batch for your pots and keep the remaining units dry, making peat-free gardening more practical on a patio, balcony or windowsill.

OUR APPROACH
Putting our commitment into practice.
Prepare one brick at a time
Place a roomy hydration container close to your pots before adding water. Follow the pack instructions and allow space for expansion. Each 650g compost brick yields approximately 9–10L; each plain coir brick approximately 10L.
Keep unused bricks compact
Hydrate only the number of units needed for the planned task. Store the remaining dry bricks in a sheltered, dry place as directed on the pack. Keep tools and materials within comfortable reach, and avoid moving a heavy container of wet compost.
Match the mix to your plants
All Purpose Compost Bricks contain fertiliser for suitable general planting. Plain coir needs an appropriate mix and nutrient plan. For plants suited to a coarser structure, consider coir chips as a component—not as a universal replacement for compost.
CHOOSE FOR YOUR APPLICATION
Products to consider for smaller spaces
Start with a 6 × 650g pack of fertilised compost or plain coir. Prepare individual bricks and store the rest dry. Each full dry multipack weighs 3.9kg; hydrated material is heavier. Coir chips are an optional addition for plants that need a coarser mix.
With added plant nutrients

Plain coir for your growing mix
Coco Coir Bricks
6 × 650g · approximately 60L total
A compact supply of plain coir for preparing your own plant-appropriate growing mix. Each brick expands to approximately 10L, so smaller projects do not require hydrating the whole pack.
No added fertiliser. Plain coir needs an appropriate nutrient plan; do not treat it as a pre-fertilised compost.

Optional coarse blending component
Coco Coir Chips
1 × 650g · approximately 9L
A coarse coconut-husk component for suitable orchid and foliage-plant mixes. Use where a more open structure is appropriate, adjusting the blend to the plant, pot and watering routine.
