Cool thanks for the info...

yeah Hydro I understand is 5.5 to 6.5 MAX!!!!

but What I was more looking for is...

Is there an advantage in haveing my water during seedling stage to be 6.0Ph as opposed to 6.7 6.5 or 7Ph etc?

I do know my seedlings will grow if I don't Ph my water at all in promix. If i simply use Tap water at Ph7. But much like everyone else I want the best It can be since I can now get a proper Ph reading of my water.

or like I mentioned above am I thinking to hard about PH? and its importance?

thanks again
