ppm pen

[CB]

just what is this meter? what does it do? and what does it read?

i think most people seem to think a ppm pen reads ppm

but they dont really :eek:

even tho the conversion isnt all that great in a ppm meter from ec to ppm it works;)

CLICK (http://www.octiva.net/projects/ppm/)

think most pens use the .07 conversion and are within +or- 50 ppm

My meter is a TDS meter and it is supposed to be off by +/-1 under a thousand and +/-10 over a thousand. Are you saying it's better to go with EC or that they are the same thing basically?
That was a good link about EC and such CB, very informative.

TDS- Total Dissolved Solids...
a TDS meter measures the total ammount of dissolved solids in a liquid
( like ferts) in Parts per Million (PPM).
I use a simple TDS-3 Hanna meter, easily found on ebay for $25 +-.

A TDS meter reads EC then converts to TDS. Different manufacturers use different conversion factors. See Cranky's chart.

bit late but.....


all work the same pretty much.... give the plant back what it ate plus what it wanted ;) and carry on with the grow

:pass:

my Milwaukee Sm802 will read EC or PPM and PH. I love it and I found it for a steal at $160.
like this one http://www.aquacave.com/sm802-phectds-meterbr-by-milwaukee-instruments-611.html for 140

lol I'm a Cheap Bastard too

how i grow via a ppm meter

rooted plants ready for food

day 1 ppm 200
day 2 ppm 150, feed back the ppm they ate and the ppm they wanted so ppm now 250
day 3 ppm 200, feed back/+ what wanted so ppm 300 now

i do this this until mid flower then it starts to even off and i just ride the wave :D

push the plant to the max like or hydro is just a waste of time IMO why we use a means to monitor ther uptake;)
