It's tests the water, not the soil. You test the water going in and the runoff coming out. From the two you determine the soil Ph very acurately.



I'm sorry but I disagree again, unless you are going to use 4 gallons of nutes all at once. You don't want to mix nutes with water and have them sit around for weeks. They can go stale and rotten. I don't see how they won't "dilute properly" if used at 1/4 dose..... How do the nutes know and why would they not dilute properly? Did they go on strike? Did the Union tell them they can't work????
That's fine. It is ok to agree to disagree, there is no harm in that. There is a million and a half ways to grow some good bud. It's all about finding your own style and comfort zone matched with quality standards.

I just follow the Cannabis Grow Bible. I do exactly what that book says and I have never have any serious issues. I am just passing those words....
