Thats interesting. Guess you need to do some research then. Most of the coco doesn't need to be rinsed anymore, Seems a couple of years ago the producers figured out the salt thing, none of that except adding water and fluffing has been necessary for some time now. May want to update your information if you are going to post it.
The only thing I have noticed with coco is the fungus knats are always there. I am experimenting with putting about an inch of flock rockwool on the top of the coco to see if that will control them. I may try some sand on the next group.
