It’s more accurate using EC. All meters measure only EC. Then convert it to PPM. Get an EC chart on your phone and use it.
I’ll disagree again and so does this source.EC is not more accurate, EC is converted into ppm using a scale.
It is good to know both because people use both. So knowing what the conversion is will help people understand when someone else uses either measurement.
If anything I would say ppm is more accurate because it uses a smaller unit of measurement, so you have a more precise number when using ppm. You just have to know what scale you are using whether it is .5 or .7.
For example, on the .5 scale, 0.1 EC is 50 ppm. So increments of 0.1 EC is equal to 50 increments of ppm, so since ppm uses a smaller unit of measurement it is technically more accurate.
100%I understand EC is giving the electrical conductivity and ppm is an estimation of total dissolved solids. But the ppm measurement uses smaller units of measurement.
For example, if I convert 1 mile into yards or inches, the smaller unit of measurement, inches, will be more accurate. A yard which is a larger unit of measurement will be less accurate because you have to round up or down to the nearest yard.
That is what I meant when I said ppm is more accurate in terms of units of measurements, and I know overall, EC will give a better measurement of actual electrical conductivity. It's just when you convert EC into ppm, it doesn't change what the EC is, it just allows smaller increments to get a more exact number of what the actual EC really is.
500 ppm is 1 EC, so 513 ppm is just slightly more than 1 EC, but if you go strictly by EC, it will say 1 for both measurements. That is what I meant by more accurate, if you know how to convert ppm back into EC, it gives you a more accurate reading of what the EC actually is.
The best thing to do is know how to convert all of it because it's not really that difficult. So when someone mentions ppm .5, .7 or EC, you will know exactly what they are talking about.
To say only use one, and not know how to convert EC to ppm because EC is more accurate, I think is bad advice. Better advice would be to learn what EC AND ppm is so you have no problem converting either one in your head when you need to. Simple 4th grade arithmetic that any human can learn very easily.
100%
Yeah... but like ya say it best they learn both and understand as it's a pretty helpful tool to have.
Again, I do agree EC is the true measurement and industry standard. Also, it can be confusing for beginners to understand the difference between EC and ppm, especially with multiple scales to convert into.
How Olds the plants and have pics? The last thing you wanna do is overfeed. More nutes does not equal more growth. It doesn't work that way so I suggest feed light you can always increase as needed... over feed and you need to flush and piss the plants off much more often stunting them.Im thinking acording to the charts 340 ppm is way to low thinking ill raise it maybe 5-600 and see how that goes
Yeah keep doing what you doing... no way would be jumping my nutes. You have em nice and healthy so I wouldn't change anything yet. Maybe a slight 50-100ppm if you really want but then give it a week to see how they respond.24 days out of ground
Could be from the soil or slight accumulation... pretty good if you ask me.Watered this Am with 415 ppm then measured the runoff it was 550 and not sure why im using soil thats been cooked so im unsure where the extra nutez are coming from
Really good advice here.in an ideal world we could get our nutrients to water ratio perfect for each stage of growth but......
now that you're testing you can keep an eye on your runoff and make changes to how you water.
without testing there's a tendency to gradually build up excess nutrients in the medium. this makes us think everything is going along just fine until all the sudden...... but it didn't happen all at once.
it's useful to use sheets / excel to keep a record as you move forward. this way you can see what results / trends you're getting in real time and adjust your actions accordingly as well as give you a reference to see what worked well and what didn't.
