What EBG said. Just substitute Hydrotron wherever he says rock wool.
Othewise, his advice is sound enough.

H'tron needs to be heavily pre-rinsed.
If you see any "orange dust" at all, keep rinsing.
Then you need to acid condition it for quite a while, then rinse again.
At least that is what the h'tron makers advise.

I did all of that and then some.
The PH just kept creeping up regardless.

Way too much work fo' dis lazy guy.
I quit using rockwool and hydrotron.
Now I use coco coir.:thumbsup::thumbsup::thumbsup:.
Stand alone, and as a root holder for DWC.

Wanna buy 45 pounds of Hydrotron?
Cheap! to a good home.
