That's my question....was the water ever ph adjusted to begin with......before it was put into the system for it's "trial run" If not.....this entire thread is not really very useful is it? That's what I can't seem to get an answer to exactly (it's water that's sat for 3 days doesn't tell me I'm afraid) and I assume you are going to use rockwool instead of hydroton so I suppose that answers that question if I can read between the lines correctly.

I honestly cannot tell if you are trying to answer eveybody's question at once or just giving out the info you feel we need to know. So far....i cannot get the information I NEED to know to help you so I will say.....good luck with your grow.
