This 600g eco coir compost block, creates up to 11.5 Litres of the optimum soil structure for your plants. Made purely from sustainably sourced coconuts, coir compost is perfect for growing houseplants, herbs, fruit, vegetables or cacti. The coir will improve drainage, air circulation and water retention, helping create a perfect environment to encourage healthy root growth. The fibres have a high cation exchange capacity, meaning they absorb, store and release nutrients very effectively, reducing nutrient leaching and helping your plant absorb plant food more efficiently. The coir fibres are specially graded, washed and buffered, using a waste water recycling facility, giving your plant a neutral, safe, gentle soil to grow in. No artificial fertilisers are included so when planted, add an organic proprietary plant food of your choice. Size: 600g
