Ok this will be my last post on the subject off EC vs ppm then I'll kindly STFU.
ppm is calculated by either using a .7 conversion or a .5 conversion.
If the meter you have uses a .7 conversion you would divide the ppm by 700 to get EC. If the meter uses a .5 conversion you would divide by 500.
Please refer to this chart...
"So what Sparat1k?!" you say, "Whats the big deal!?!"
Well it's a big deal because if you use a Hanna ppm meter and your plant burns at 1500ppm to somebody using a .7 conversion meter that would mean that they would need to get to 2100ppm to get to tip burn.
That's a 600ppm difference or 40%! PPM comparisons ain't apples to apples by a country mile.
So I ask again... Why don't we just convert to EC so we all speak the same nutrient language, its easy, its quick and all the cool kids are doing it
