Coco peat expands significantly when hydrated, typically increasing its volume by **4 to 5 times** from its compressed form. This makes it easy to store in compact blocks or bricks before use.
Coco chips typically come in medium (5-15mm) and large (>15mm) particle sizes, though some finer grades may exist. The larger the chip, the more air is retained, improving aeration around plant roots.
Coco chips have a slightly higher bulk density compared to coco peat, ranging from 0.12 to 0.2 g/cm³. While they are still lightweight, the bulk density is higher due to the larger particle size.
Coco chips retain less water compared to coco peat but still offer excellent moisture retention, generally able to hold 4-5 times its weight in water. This makes them ideal for plants that require well-draining yet moisture-retentive conditions.
Coco chips have high air porosity, which encourages healthy root development by allowing air to circulate around the roots. This property is especially beneficial in hydroponic systems or when growing plants that require good root oxygenation.
The pH of coco chips is typically 5.5 to 6.5, which aligns with the same pH range as coco peat and suits most plant species.
Like coco peat, coco chips also have an EC of 0.2 to 0.5 mS/cm before being processed. However, as coco chips have lower nutrient-holding capacity, they are often mixed with other media like coco peat or perlite to improve nutrient availability.
Coco chips do not compress or expand as much as coco peat. However, they still expand when hydrated, though to a lesser extent. Their large, chunky structure helps to maintain an open, aerated root zone.
Coco peat powder consists of fine particles, often less than 0.5mm in size. This fine texture helps with seed germination and gives the soil mix a smooth, uniform texture.
The bulk density of coco peat powder is relatively high compared to coarser coco products, typically around 0.1 to 0.2 g/cm³, depending on the level of compaction.
Coco peat powder retains a significant amount of water, with the capacity to absorb up to 8-9 times its weight in water, similar to coco peat in block or loose form. Its fine texture helps retain moisture, making it suitable for seed-starting mixes and indoor plants that need consistent moisture.
Although coco peat powder retains moisture, it has a slightly lower air porosity compared to coco chips. It is often blended with other coarse materials like perlite or coco chips to improve drainage and aeration in potting mixes.
The pH of coco peat powder is also 5.5 to 6.5, which is neutral to slightly acidic and fits the pH preferences of most plants.
The CEC of coco peat powder is typically around 40-60 meq/100g, which is similar to coarser grades of coco peat. This high CEC ensures that the material can hold onto essential nutrients and release them to the plant roots over time.
Coco peat powder generally has an EC range of 0.3 to 0.5 mS/cm before processing, but like all coco products, it is often washed and buffered to remove excess salts to avoid harming sensitive seedlings.
Being finely ground, coco peat powder tends to compress more than coarser grades. It expands when hydrated, increasing its volume by up to 4-5 times.
