Buffering Brick Coco

Recommended Posts

If you are buying bagged or dry coco from Hydro store, you don't need to flush or buffer. If you are buying bricked coco from bunnings I would flush and buffer, as Coco naturally has a High salinity, it has a preferential CEC meaning it is chock full of potassium chloride naturally. Buffer removes the potaassium chloride and fills it with calcium. 


When I was treating my own coco I made the buffering mix from Cal nitrate, mag nitrate, mag sulphate and chelated iron.


So using cal mag, should be fine.

I get the HyGen bricked coco - makes approx 70L after ya hydrate it . Comes pre buffered they say . 1/4 the cost of buying the 3L bags and a lot easier to transport at about 50x50cm block 150mm thick .

I buy a 100L bag of perlite and mix that through at 30% perlite .

I have a big 160L tub at home and throw it into that with warm water to mix it all up then add the perlite .

Does the trick for me .

Yeh, why i stopped using cheaper coco from bunnings. Unless you need thousands and thousands of litres it's just easier to buy pre buffered and flushed stuff from a hydro store. I mean even bunnings have PineGro branded 30l bags of pre buffered and flushed coco as well. 12$ for 30L is on point with hydro store prices too tad cheaper.
