Great article, Karen. I've used only 2 different brands of coir. Sun Leaves was the one that was an absolute disaster, to the point where I emptied my containers of it after only 1 season. I believe it was not properly rinsed and had a high salt content. I flooded one of my containers that was using it and it definitely helped, but it would take a lot to rectify that problem. Even when I was trying to rehydrate the Sun Leaves coir, it took forever and a lot of manual breaking up of the chunky bits.
I've used the CocoTek brand from General Hydroponics with quite good results. Reconstitutes very easily. I've never checked my water pH either....hmmmm.......
