Description
Buffered Coco Peat Bricks, approx.: 5kg : Coco peat bricks is a substitute for peat, because it is free of bacteria and most fungal spores, and is sustainably produced without the environmental damage caused by peat mining. It can be be mixed with sand, compost and fertilizer to make good quality potting soil.
Coco peat (coco coir) generally has an acidity in the range of pH – 5.5 to 6.5. It is a little on the acidic side for some plants, but many popular plants can tolerate this pH range.
Coco peat can be re-used up to three times with little loss of yield. Coco peat from diseased plants should not be re-used.
5Kg brick makes about 50 – 60L. Please note that 5kg weight is approximate (Between 4 and 5kg. The block weight should not have an effect on the volume yield).
For the Buffered Cocopeat there is no need to buffer as it has already been done, but it still needs to can be flushed/rinsed before using.
Cocopeat, pressed into Coco peat bricks, has a negatively charged complex, surrounded by a couple of positively charged ions: sodium and potassium. Because these elements stick to the complex, like iron to a magnet, there is no danger to the plant root initially. The problem starts when fertilizing with calcium. The calcium will push the potassium and sodium aside and take their position. Consequently, the calcium that is connected to the complex won’t be available to the plant, while sodium and potassium that are released into the water will be available.
To avoid this ‘time bomb’ problem, the Cocopeat needs to be  buffered. In buffered cocopeat the ion exchange, as we call the process where calcium pushes the other ions off the complex, has already taken place.
