Well 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.
