I am on my second cycle using floor dry in place of perlite, and have noticed on this run using coco/floordry mix, my plants seem to have much stronger thicker stems than previous runs in coco/perlite mixture. Last run I mixed the floor dry with mostly happy frog, peat, and bit of coco. Being it was a primarily soil run I ph'd to 6-6.5 and didn't have the thicker stronger stems. What I am wondering is, does the lower ph required for coco have an effect on releasing silica from the floor dry? I was reading a thread a couple days ago and another member (though I forget who. maybe spurr?) alluded that he/she may be experiencing the same thing. This got me thinking maybe it's not all in my head, what do you guys and gals think?
