Okay everyone. I am neither confirming nor denying any of your statements. All I am saying is that it does not matter what you use scale wise. (yes you will want a good meter) All I am saying is that whichever you use just make sure to keep your reading in a specific range during the relative growth cycle.
I dont know about everyone else here but I for one do not have the equipment to measure true TDS as stated by ttystikk. Nor do I feel it is necessary.
I am not trying to start any arguments but I was once told that "It is not so much how good the equipment is that you use, rather How good you use the equipment that you have"
Ya Ted I agree. So we just state that our individual results are compliments of meter x,y or z.^ Tyystikk YES. Like you said before Genx, as long as you stay in the range you're good...but how do you know what range you're at if your meter is off?
That's why a standard really does matter.
A good quality meter too!
Yes you can do a great job if you were all on your own and you found your sweet spot with your meter.
But now lets say its faulty and reads a few whole points higher on your meter.
Now lets say your sweet spot range would be 2.6-3.2 on your meter.
Then you come on here with pics and all saying your EC is 2.6-3.2 and your plants love it. Someone else reads it and tries it.
That's why a good meter and a standard unit of measure is important...
But you are right in the points you made.
i would like this thanksWell I was on another forum and saw a thread about this subject. I did not want to join yet another forum and yet I felt that this topic was worth mentioning so I decided to share it here.
There are arguments out there as which meter type to purchase weather it be a TDS/PPM meter or an EC/CF meter. (Yes I know that there are combo meters out there but that is not what I'm on about so bare with me please.)
Some are saying that EC is more accurate than TDS or vise versa, when in truth they are both within 10 % of each other. You can sit and do the equations all day long yourself if like. Just make sure you know your meters conversions as they are different from manufacturer to manufacturer.
None of this however really needs to be of concern. Just make sure you have a meter that reads from 0 to 1999 meter. As you check your solutions take note of your plants health and reactions to different levels and keep them in the same range. It wont matter if its EC , TDS, or MOON UNITS as long as it stays within your target range.
There is an attached excel document (converted to pdf ) that I use to monitor and control my nutes,temp and pH. I have adapted this chart from an SPC (Statistical Process Control) chart from work.
The ranges in this chart are from the books "GROWING ELITE MARIJUANA" and
"THE CANNABIS GROW BIBLE". However the values I have entered are all arbitrary to be used as an example.
I know it seems a bit much, but it has really helped me keep everything in check.
If anyone would like to have this SPC chart just let me know and I would be happy to send it your way.
I know its set up in hours but that is easily changed.
