Looks real nice so far. Congrats.

When you get your water PH test kit please let us know how the two devices compare. I've been told not to buy tester you have because the water run off test is more accurate. Sounds like it's working for you.

I'm looking forward to when they come out with one that you stick in soil or water and it says something like, "The reason your leaves are curling is because the PH is 4.7 and the PPM is 1940." or "Your nutrients have a Magnesium deficiency." or "Your cousin peed in the reservoir."
