@MeEasy OK I know. It’s 3:30 am and I’m scanning TGSC website and found What’s the Best Way to Use Earth Dust? A Look at Your Options
In regards to peat moss it says it is slightly more compatible with ED than coco. As for ph, this is taken directly from the article
“However, because peat moss is not a humus, that is, not a mixture of organic compounds making up a soil, you may want to control the pH of your water as with coco coir. Peat moss has a much higher CEC (cation exchange capacity) than coco, but still less than a full mixture of humic elements.”
Referring to the article’s comments on coco and ph, the article states:
"For Earth Dust users, however, this is less than ideal [ coco coir’s ability to allow the grower to control nutrient content by adding synthetic nutrients in a constant regimen.] . Earth Dust is designed to simulate nature in that it uses readily available organic matter in the medium. This is not to say it’s impossible. If you are using coco coir, we suggest you start with 3-5 tablespoons of Base and 1 tablespoon of Boost for every gallon of coco coir. Blending in some additional organic material such as peat moss may prove helpful as well. Paying attention to the pH of your water is more important with coco coir as well, since the low CEC limits the relative amount of ionic exchange, which in turn limits the microbial capacity to regulate pH. A good range to aim for in the pH of your water when using coco is 5.8 – 6.5. Coco coir is also not very good at retaining water, so a much more rigorous schedule will be in order.
In short, treat peat like coco for ph purposes.
Thanks for your follow up and your diligence.
p.s. I was on the site thinking about a comparative grow of clones from the same mother using Earth Dust and a good quality soil Vs coco using Jack’s and other supplements I customarily add.
it sounds like peat is going to be pretty much the same thing as coco which I consider growing hydro with a sponge in the water and throwing in dry organic nutrients isn’t going to work without something else for the microbes to eat.
and proper names. Thanks a ton for doing the research for 
I recommend using something with less nutrients but it’s okay to use it. The key is to do your initial mix with 1 tbs/gallon of soil and cooking it a little longer. I use happy frog only because I get a good deal on it here in town
the link to my growroom thread you are welcome to come check it out it shows like a year n a half or my growing all with Dust along with a bunch of bs’ing about just about everything
