The guardian series doesn’t calibrate the conductivity meter. I can calibrate the ph probe but the conductivity probe I guess you clean and check it
This I did not do, please explain
Yeah but using nutrients like megacrop even weighing out the nutes by scale or tsp can vary so this isn’t always the right approach for everyone.
Conductivity varies with the temperature of the medium. The Bluelab corrects for that.
Well always reading 2.6 for the 2.77ec solutionConductivity varies with the temperature of the medium. The Bluelab corrects for that.
Yeh, the EC probe in the Bluelab MONGUA - I've got one, as well - can't be calibrated and you can't replace it, either.
When you calibrated, did you replace the shroud? If not, that will throw off the reading but, if it's always reading 2.6, I'm getting the feeling that you're going to need to "stimulate the economy".
Oh - thanks for the clarification.
Guardians good for +-1. It is -1. But watching all the calibration videos it was saying it should say 2.7,2.8 or 2.9. Maybe 2.6 is another but I contacted bluelab so we’ll see. My other bluelab equipment is down due to not being used for 3 years and will not calibrate.
I’m running soil with megacrop and running megacrop not everything weighs the same so I use a scale. I use the conductivity to find out how much of the additives to use with the stage I’m at so I don’t over feed. I am not a noob when it comes to this stuff, different nutrients need these gizmos. Sure my next run I won’t need my conductivity pen but this one does. Using any of these Feed schedules online you can find aren’t for everyone. I found out I have a 250ppm tap, and seeming low, it’s still easy to over feed the slightest bit and have to put that into the persuasion. I know all the different types of growing and how people do it, but I happen to be using this meter. To each is own. This is how i do it and have done it and it works for me in great measure.
0.1± is the spec? Thanks for posting that — I was too lazy to check, to be frank.
Appreciate your guidance and help here my friend. This is why I love the cannabis communities. I’m sorry for the summer of 2017! I too had a mishap with electricity and had an amazing lemon skunk go to waste. Was running DWC at the time and she was stunning but she went through too much stress and I had to cut her down in preflower
Agree. Some very knowledgeable and helpful folks on these sites.
Ah, that sucks. Funny that we both hit a "showstopper" event at the same time. That was my first grow and I was pretty bummed so I packed things up.
