Coco peat, also known as coir peat or coconut coir, is a natural byproduct derived from the processing of coconut husks. It is a renewable and sustainable alternative to traditional peat moss, often used in gardening, horticulture, and agriculture. Categories: Agro Products, Organic Fertilizer, Organic Manure Tags: Agriculture, Coco Peat, Cocopeat, Fibre, organic fertilizer, Plants, Potting Mix Description Coco peat, also known as coir peat or coconut coir, is a natural byproduct derived from the processing of coconut husks. It is a renewable and sustainable alternative to traditional peat moss, often used in gardening, horticulture, and agriculture. Growing Medium: Coco peat is widely used as a growing medium or soilless substrate for growing plants in containers, raised beds, and hydroponic systems. It has excellent water retention properties, holding up to 8-10 times its weight in water, while also providing good aeration and drainage for plant roots. Soil Amendment: Coco peat can be mixed with garden soil or other growing media to improve soil structure, water retention, and nutrient availability. It helps loosen compacted soils, increase moisture retention in sandy soils, and enhance drainage in clay soils, making it suitable for a wide range of soil types and plant species. Seed Starting: Coco peat is ideal for starting seeds and propagating cuttings due to its light texture and ability to retain moisture. It provides a sterile and weed-free environment for seed germination, while also promoting healthy root development and reducing transplant shock. Potting Mix Component: Coco peat is often used as a component of potting mixes and growing media for container plants, both indoors and outdoors. It helps maintain a consistent moisture level in pots and containers, reducing the frequency of watering and the risk of overwatering or underwater Packaging Size: As per user requirement Packaging type: As per user requirement
