You are correct, the lower pH (below 6 I believe) is hospitable for trich and other molds. Optimal pH for agaricales is slightly acidic to neutralish, around 6.5-7.5, iirc.  Above that should prevent colonization and contamination.

you saying i probably shouldnt use my RO filtered water to prep coir? you saying its not only pointless to filter out mag and K, but potentially detrimental?

yes i think thats what youre saying. got it.  fuck.  why cant i learn something *before* i make a mistake for once?

Ha, I don’t think it’s that crucial as far as coir prep goes.  RO is slightly acidic and CO tap, depending where you live is probably 7-9.  I think Denver is 8.8.  Coir has a pH of 6.5-6.7.  I use tap.  I save the RO for the carnivorous plants.

hmm. well..  it tastes fuckin great.  and i want my shrooms to have great tasting water, myco.

It may come out of the filter at 7 but will start dropping as it absorbs CO2 from the air.    Like I said, I don’t think it matters one way or another.

I keep my RO water resevoir airated for my ganja, so the ph stays at consistant @ 7.0 ph... but I read ph does drop due to co² absorbtion, I didn't know that..  I've been using RO water for cultivation for years, my tap water is fucked... my dogs won't drink the tap water and my cacti hated it, so I quit using tap water for anything other than washing my ass...

Oxygen is too reactive to dissolve into water past a certain point. But CO2 forms H2CO3, carbonic acid, which will accumulate and drop the pH. Still water with a lower surface area will accumulate more than turbulent water with a large surface area.
