The Coco Peat for Planting we supply has been aged, washed and buffered.
o To guarantee the stability of the cocopeat the coco pith has been aged before further treatment. Aging is done to avoid problems with breaking down of the coco pith and to improve the stability and reliability of your growing medium.
o To avoid surprises with high EC’s, the EC is washed down to less than 1,0 mS/cm in 1:1,5 dilution.
o Because coco pith has a negatively charged complex, there are positively charged ions primarily consisting of sodium and potassium on this complex.
This doesn’t cause many problems to start with, because these elements are locked in the complex and therefore not available to the plant root.
When fertilizing with calcium or magnesium, the calcium will take the place of the sodium and potassium in the complex and make these available to the plant root.
To prevent from this highly unwanted situation the coco pith is buffered. During this process the ions are exchanged and the excess of sodium and potassium are washed out.
Note: When soaking 5Kg Coco brick, use 20L water and 50g Cal Mag to buffer coco.
When soaking 600g Coco Brick, use 2.5L water and 6g Cal Mag to buffer coco.
Soak the cocopeat in the solution for 12 hours. Drain any excess solution and rinse the cocopeat with pH balanced water.
Cocopeat 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 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.
