Hmm...if that fertilizer analyzer actually works, I'd say that would be a good little gadget to keep around! I guess I'm still stuck in the stone age, as I still use litmus strips and chemical aquarium pH kits to test my water/runoff. Luckily, I rarely have problems with my pH. My tap water is always filtered, and my pH pretty much constantly hovers around 6.5.

Still, probably would hurt me to "get with the times" and invest in more of these nifty contraptions. If you get recurring accurate readings with that thing, please be sure to make a note of it & I'll have to keep my eye out for one!
