i don't know. from the tip? or the balls?How are ppms measured?

So please tell me now how TDS and EC meters are different when you don’t even know how TDS is measured lol.i don't know. from the tip? or the balls?
Exactly, because TDS Meters measure conductivity,good points but i don't know anybody that uses gravimetric analysis for a hydro grow
Electrical, or specific, conductivity of water is directly related to the concentration of dissolved ionized solids in the water. Ions from the dissolved solids in water create the ability for that water to conduct an electric current, which can be measured using a conventional conductivity meter or TDS meter.
did you read the difference? a tds meter also measures non conductive substances. lol. an EC meter does not. lulz.So please tell me now how TDS and EC meters are different when you don’t even know how TDS is measured lol.
How is ppm measured? You have to know the volume of the solution AND the substance dissolved in it. You’re tell me TDS pens measure how much solution you have? Loldid you read the difference? a tds meter also measures non conductive substances. lol. an EC meter does not. lulz.
That is where the major difference is. that's pretty cut and dry
As I said dumbest shit I ever heard lmfaoYes they transpire out, mainly through the stomata on the sugar leaves. That's why the trichomes turn amber on the sugar leaves before the buds. They're not amber from ripeness but dirty from nutrient residue.
I just submitted a patent application for this revolutionary device I've invented that will allow a grower to reclaim and reuse those nutrients. The cost of the current device won't make it feasible for a small grower to use but I'm targeting the large commercial grow operations where nutrients can be a significant cost. This device will allow them to reclaim those nutrients that transpire out of the plant during flushing. I have several in trial right now and preliminary results are very promising. One very large grower that is using the device has been able to reclaim over 50% of their nutrients leading to significant savings.
If there is enough interest I might start working on a smaller device targeted towards consumer grows. The problem is getting the price point down to a price affordable to the consumer. $300 is the target price I think I can achieve which would be a good value to the consumer while allowing for a modest profit.
You could have just said I don’t know what I’m talking about. Enjoy.anyways, adios. it's happy hour here.
Here let me help you so you don’t look so silly in the future.EC is looking at how well electricity can pass through the substances that are present in the water. TDS is looking at the dissolved solids in the water and looks at both EC generating particles as well as particles that don't conduct electricity which is where the main difference occurs
Noobwhat if he's using an EC meter and then converting his soaked buds back to ppms? does sugar read on an EC meter?
What are Total Dissolved Solids (TDS) Meters?
In order to measure the effectiveness of your RODI filter, many units have built in total dissolved solids or TDS meters. A TDS meter is used to determine the amount of dissolved particles in the water, usually in parts-per-million or ppm. However this is not necessarily true. TDS meters are actually measuring electrical conductivity (EC).
My guess on this would be that there's some variability in the purity of the sugar. I spend a whole lot of time making different sugar solutions around the house. Beyond for cocktails and hummingbirds, I also keep bees and make large quantities of sugar syrup feed for them depending on the time of year. There's a big difference in the qualities of sugar out there...some dissolve cleanly, some leave foam or scums of different types and amounts.my bad. my EC meter can measure the difference between distilled water and sugar water. how come a Hanna can't???View attachment 5159467View attachment 5159468
in case you can't see, it's a 1 in the distilled and an 11 in the sugar. or to be really technical, 11 microS vs 1microS.
like i said an EC meter is not the same as a TDS meter.
The Difference Between TDS and EC meter
Even though you can use EC results to determine TDS levels, these meters are different, which is why the conversion doesn’t provide exact TDS results. TDS meter measures both particles that generate EC and those that don’t carry electricity.
Thus, EC to TDS conversion factors vary, depending on the contents that are included in the sample. These factors generally have a range from 0.4 – 1.0. That said, the substances that doesn’t impact the levels of EC, yet they do affect TDS levels, make EC measurement insufficient to determine the TDS values.
EC is usually measured and converted to TDS to provide the approximate TDS values. Furthermore, TDS meters automatically convert EC value which is determined by the conversion factor. To get the real TDS value, you need to take your sample to the laboratory where it will be further examined. You might think that it is better to use a meter that has the widest measurement range. However, using one meer that focuses on a specific area, increase the accuracy of your results.
slainte!
Great cut and paste, you actually proved yourself wrong with it.my bad. my EC meter can measure the difference between distilled water and sugar water. how come a Hanna can't???View attachment 5159467View attachment 5159468

What sugar are you using that leaves foam or scum?My guess on this would be that there's some variability in the purity of the sugar.

I've tried a handful of different brands. The big two or three are just fine, but some of the no-name and small label stuff certainly does do that.What sugar are you using that leaves foam or scum?
I'd like to see this device that takes transpired nutes from the plant and turns it back into usable nutrients. Anyone else wanna see it??i've been offering to wash everybody's (hydroton) balls to reclaim nutes. it's been a hard sell so far...
