If you’re new to hydroponics and have NO clue what all of the terminology means, this video is for you. Even if you’re an intermediate grower and want to know what EC is, what TDS means, which you should use, and how it all connects to pH, make some time to watch this one today.
The truth is that EC or electrical conductivity is the purest way to measure your nutrient concentration. TDS or total dissolved solids is a calculation based on EC that meters perform internally. TDS is measured in PPM, or parts per million and the calculation can vary based on the conversion factor.
This is why you must know the conversion factor your meter is using if you’re using TDS. Or you can simply switch to using EC and never have to worry about it again!
Today’s video is sponsored by Apera Instruments, makers of water and soil testing probes and meters. They kindly donated the PH20 and PC60 meters for me to make this video.

![VIDEO: How to Prepare Water For Hydroponics [Updated]](https://i0.wp.com/gardeningvlogs.com/wp-content/uploads/2021/12/12948/hqdefault.jpg?resize=445%2C265&ssl=1)
Still works in 2021. Love it. Thorough video.
Very good explanation. I was familiar with pH testers , pH up / down etc. But was a little confused about the EC and tds tester/ meters and what the difference / what to go with. Now I am ok with it. But have additional one question above
If one use a tds or an ec meter how does the total dissolve solids or electrical conductivity measurements coorospond to how much N or P or K or trace nutrients to add. It only tells you in general what ppm not what constitutes how much nitrogen , phosphorus ,.. etc
In soil growing the have soil test / testers to give you the measurements of all the different major plant chemical N ,P ,K , calcium , boron ,…etc what is the equivalent to this in hydroponics growing as the tds / EC seems to only give you not the full story on nutritional break down as well as what floralgrow hydroponic solution to add more of
It seems tds/ec tester could be enough for a farmer to have a frame of reference on when to top up or redo his fertilizer procedures but some times your going to need the chemical break down to focus on a problem or troubleshoot the problem down to the very nutritional chemical deficiency cause. Is there no tester for this. Maybe it's only send away water test sample not sure
Dear please suggest us minimum 40k TDs detecter portable TDs meter brand and model
Yeah some of that was cool but you blew my fucking mind and didn't give me a chance to soak in anything b4 something else. How about a breather in between. You speak in run ons how
I went crazy trying to understand the included directions. Should of looked you up first! Thanks
Great video, came here for EC and this was super helpful.. i just found it hilarious when you named all 4 units and said both the abbreviated and full versions and when you got to pH you just made a face LMFAO
"What I'm gonna do is", repeatedly doesn't teach, it distracts and fatigues. Listen to your delivery before publication. You could eliminate a few minutes runtime just by not saying, "what I'm gonna do is, is the following".
Thank you, thank you, thank you! I went to so many videos trying to find a clear explanation for EC and TDS and every other person made it made it seem much more confusing than it had to be. I'm only 4 and a 1/2 minutes into your video and you've already given me a much clearer understanding of what these things mean. You are explaining the information technically, but also clearly explaining those things that are specifically important to a grower. Much appreciated!
Im total agree when ph its 6 iveen 8 its ok but never less of 5.5
I've watched a dozen videos on this subject and yours is, hands-down, the best one. I realize this is a 4 year old video, but I hope you see this comment. The only thing it was missing was the proper readings for various vegetables.
This is a racist video…..math above a 6th grade level..
Thank you. This is what I was looking for.
Ok I need clarification.. My ppm is reading 700ppm but out to the side it says X10. So 700 times 10 is 7000. There's no way, the plant would be dead at 7000ppm right? Which number do I read? 700 or 7000?
I will watch when I have time. No one else has really hit this topic on the head.
0:23 is pH stands for potential hydrogen
Thank you, sir!
Please in spanish hahahaha
Probably the best vid on this subject I have seen
Screaming music in the background is very distracting.
Music distracts….
When using soil and testing runoff what needs to be taken into consideration re: dirt in water.
I have well water and the EC for it is 0.40. My 3 part hydroponic solutions guide says to use an EC of 2.0. Does this mean that I only add 1.6 EC solution of nutrients for a total of 2.0 or do I add an EC 2.0 of nutrients for a total of 2.4?
Music is too distracting
