A quick note to re-re-re-re-re-re-iterate that the cheap, 2 prong soil ph meters are not only extremely unreliable but will take years off your life due to stress.
A couple posts ago (prior page) I was beside myself with anxiety because:
A: I had just wake & baked a huge bowl of Romulan x White Widow
B: My soil appeared to be testing at 4.9-5.1 ph when the day before, it was at 6.4-6.5 ph
I freaked, I was searching for answers, I contemplated soaking it with down.
Cut to this evening...
I suddenly remember that whilst generally doting about my grow cab and making sure everything was organized,
I knocked a bottle of Tiger Bloom down into the grow area and it hit my aforementioned, cheapo soil ph meter.
Now as I understand it, these meters measure current traveling between the two prongs in the soil. If the two
prongs are closer together than they should be, the reading is going to be WILDLY inaccurate.
I looked at it and it was visibly nonparallel. I bent it back and low and behold....6.3-6.5 ph.
These things are worse than unreliable, they are sadistically misleading. Some times you just have to learn
by getting your butt handed to you in person. I went in figuring, "I have a budget and this is one of the things
that I can skimp on and still get by" It isn't. If I had trusted that meter enough to make chemical changes,
I'd be much worse off because of it.
Thanks Stick, for being patient with me and pointing me to a workable solution (huh? huh? double entendre?)
