yea that asshole passed me in post count! he's be doing overtime round this bitch!
speedtest.netI'm up north. how do I find out what my mbs is?
here's a speed test:I'm up north. how do I find out what my mbs is?
beat me on that onespeedtest.net
Does the phrase "Slow Down There Cowboy!" mean anything to you?60 seconds too slow aye?

it's the slashdot you're-posting-too-fast warning.that wasnt my fault....ill blame that on my cache
i didnt see it
Here is Earl's response to my question: Why does RO water destroy your pH meter (if you want to read the post it is here: https://www.rollitup.org/hydroponics-aeroponics/57961-simple-ppm-question-3.html#post646230)thanks but I don't do r/o yet and or don't have a meter. I will keep that in mind tho and would really like to here the quote too.
A pH probe is basically a sensitive voltmeter,
and converts the reading in mV that it gets,
into a digital number representing the pH.
A solution of neutral pH should have a mV reading of 0.0.
Two chemical solutions can have the same pH,
with one solution having a higher ionic value.
pH calibration solutions are made with High Ionic chemicals.
High Ionic solutions will cause the meter to react faster,
than low ionic solutions.
RO has little or no ions.
Two potentials are needed to make a pH measurement:
1. The sensing electrode provides a potential
proportional to the logarithm of the
hydrogen ion activity,
in your nutrient solution.
2. The electrode reference solution inside the probe,
ideally provides a stable and consistent ionic potential,
independent of your nutrient solution.
Comparing the ions in these two solutions
gives an electrical potential
we can read on the meter.
Since the RO has no ions,
ion transfer occurs
from the electrode reference solution in the probe,
to the RO.
Once the ions are reduced in the electrode reference solution,
or depleted from the electrode reference solution,
the probe becomes slow to calibrate, or totally disabled.
Ph adjusting RO has the same ionic problem.
just remember to always add nutes before sticking your pH meter in which is easy since you shouldn't adjust pH until after adding nutes.Although I did read that stuff, hmmm. too much for me right now. slow down cowboy! With my limited experience I think I still would have only tested it after adding nutes. But lord is right. mom says! listen!
ohh wait your saying even with the nutes added it will still mess up the meter. I'm going to read the post linked just because.
can someone elaborate (In retard terms) on not checking ph in ro water.....I use ro water from a place less than a mile from me....25 cents a gallonand oh yea... i wont quote email.... but he informed me that you should never do a ph reading on the RO water.....it could possibly fuck something up!!!
but of course you ph your water after the nutes......
just some food for thought....you know when mother says the stove is hot...you should listen!!!!
