Im just going to throw this out there.
I thought roots excelurator was going to be the sickest shit ever, Im sorry.. I don't think so. It kicks ass and takes names at one small section of the grow after which time I found the growth rate to be almost exactly the same using various sterilizing products*(this is in a rdwc/dwc enviroment}*.
So when did roots excelurator kick ass you may be wondering?
well right after roots start forming I added to my aero cloner roots blew up when using it cloner next to it much slower growth, also transplant to the hydro clay.
I don't use a chiller so Im going to stear people away from benefical microbes in their main rdwc system unless you are using a chiller, first because water temps without a chiller are generally higher, if you have benefical bacteria it will also use oxygen from the water, thats no bueno

are roots need the oxygen.
Secondly, its just a personal pref, but I don't like how it stains my roots, I like bright white roots which tells me things are going good, I personally stay away from products like GH Micro, and use canna aqua. which performs amazing in rdwc systems.
So I still have a lot of info to put up... but just wanted to throw this up for you guys ..
