ALL coco coming into the states is left out in a huge lot for a year or two to break down, during which time they are "flushed of all salts" by continuous monsoon rains. They break it down and sift it, then let it dry, then sift again and compress it. ALL coco that you buy (even canna) is imported into the US as a cheap, "shitty" brick of compressed coco, which is usually rehydrated with a light solution of calcium nitrate (sometimes not) prior to packaging.
I water the shit out of coco, most people I know having trouble with coco do not water it enough, the compressed bricks need to be saturated at all times, if you are having trouble with them use warm water to expand them. IDK what all the jazz is about flushing and soaking compressed coco, I've never once done anything more than add water until it's the right consistency and have had great success with almost every brand of coco.
