just cause folks disagree, doesn't mean it's arguing. i thought you mentioned coco, my mistake. i re-read, it was pharmacan. yo, yes sir, i know about coco ph checking. you have to take some coco from the root zone to check ph. but i stopped checking my coco ph long ago. i too won't post here again. don't wanna hijack. relax houndman, this is supposed to be fun!
