quoting myself is silly said:I don't have an answer, just another question: Do you really need to avoid pre-rinsing? I've used all sorts of coco, but after one bad experience I always rinse and pre-treat it now. I'm much more re-assured and rest easier knowing for sure that the coco is free of salts (because I measured the rinse runoff ppm), and adequately pre-loaded with nutrients, calcium and magnesium (because I put the nutes in there and measured).
Oh, on topic -- I did find my last few Botanicare coco bales to measure very low on initial runoff ppm.
Unfortunately his one response on the other forum was just me, disagreeing with all of you. After a bad experience in a recent crop I've resigned myself to rinsing and pretreating all my coco.
Agree 100%. I always rinse, no matter what brand I buy. It's such a simple precaution that it makes no sense to me to skip it.
