Ppm to ec

[dpac]

 

Hey guys im growing in coco and perlite

 

What conversion do I use to convert ppm to ec?? Im a little bit confused now as im seeing different methods and charts .

My understanding is 1000ppm is 2.0 ec

Is this correct

 

Cheers guys

Yeah that's the usual conversion but sometimes things are read in a different ppm which fucks it around even more. I've posted a conversion chart somewhere just recently when another grower asked similar question

To get an EC value, multiply the ppm reading by 2 and divide by 1000. Thus, if your EC is 1: 1*1000/2= 500 ppm.

What kind of metre do you have? Bluelabs ec pen(not trunchon) are $100 from misterhq on ebay....youll pay double that in tye hydro shops round perth haha... will read tds, ppm700 and ec [emoji16]

Haha it equals 550 ppm [emoji16][emoji16] sorry maths ocd couldnt help myself [emoji23][emoji23] and that would be on ppm 500(tds).... most nutrient companies use either ppm700 or ec

  Indeed it reads 550 on the chart. I was reproducing and reading something completely different.

 

Here is a table with truncheon ec for those folks that aren't using the Bluelabs ec pen.

I just dont get why they have to make so many different types of meters!! I got caught out buying a h&m ec3 meter years ago. Admittedly i was in a hurry at the time and prob should have asked more ?'s when buying it .... but i spent the next 3 months wall bashing every night , trying to convert microsemens into ec!![emoji23][emoji23] never again . ill only ever buy bluelab meters both ph and ec.... worth every penny imo[emoji16][emoji16]
