peat moss pH is 7??? help

[leesus]

I have organic peat moss and Perlite. Every single thing I read says pH is low between 4 and 5... mine is 6.5-7.5. I'm using pH water to rinse it that is around 5.8. I'm so confused.. do I need aluminum sulfate or dolomite lime to buffer it??

Anyone? I thought this was a soil less grow. So do I need pH for hydro or for soil? Why are they different?

The difference between soil and soil-less is that soil has nutriets for the plants already in it. Soil less is an inert media, meaning in contains no nutrients for the plants. When growing soil less you'll want to ph to the higher end of the hydro spectrum. 5.8-6.2.

What if I can't get it below 7? No matter what i do it goes back to 7. Someone told me 7 is fine for this medium and grow. Is this true?

So why does soil need a higher pH?
