[weezer]

hey guys/gales; a friend of mine gave me an ec meter .. iam using pond water(no choice).the ec is .49... i also got new fertdutch nutrient formula, a two part liquid..when i fallow the mixing directin 2.5 ml per liter the ec reading barlt changes ..the target for transpant is 700 so i put 5 mil per liter ;ec reading .66.....so does any body use this stuff or help me with reading

Do a google search for your type of meter.You'll find a spec sheet on it,somewhere.

You appear to be confusing two standards, EC & PPM. 700 is a ppm number. To convert EC to ppm you need to multiply the EC by a factor (I think it is 500 - but I'm not totally sure that's the right factor). So, .66x500 = 330ppm.

Do like Ga Grown said - Google your meter and read the manual and find out what the correct conversion factor is.

PC is right....different meters use different standards including x500, x700, and x650 (mostly europe) You need to know the conversion for your meter.

And I'm not going to ask why you are using pond water with an ec of .49.....nice amount of crud in there....why would you want that in your hydro system?

thank you for help;...G.G. i will goggle and search some more..pharma cam; yes i could be cofusing ppm and ec that is why i need help i know nothing about these meters .. i was just wanting to use a easier fert.....west houdthank you for input i have to use pond water because my girls are in an out buildingnear a pond .. and bringing water in is hard the amount they use . i dont think it will hurt at least i hope it does not .. do you think it will make different, i am using soil

ok guys i went and done some research i went to the fert mix(dnf)to check on ec targets .. that is what it says rooted or seedling ec 700.. veg 1000 working way to 2000 ec.. as i found out more i find that is crazy to have ec like that......

so how does this sound seedling .2 to .5 ec 100to 200 ppm
early veg .6 to .8 300to 400
full veg .9 to 1.4 450 to 700
early bud 1.5 to 1.9 750 to 950
full bud 2 to 3.2 1000to 1600

My mistake....thought you were going hydro.....;) The thing is.....e.c and ppms are used for hydro applications......not soil. That's why I was asking. If you're growing in soil you really don't have to deal with e.c. at all.
