Grobo ph and Ec probes

[Suffland1109]

Hey everyone is there a alternative to the grobo probes if they go bad I know you should change ph every year and EC probe every 2 yrs please help

[Mr.420]

The Grobo PH an EC probes are made by a company called Blue lab and can be purchased on Amazon.ca or .com Also I think I seen a previous post of yours asking about the Grobo start nutrient Packets, I seen some available on Amazon as well but limited quantity.

Hope this helps.

I see blue lab ph probe but not the EV probe of possible can u put link here’s for EC probe

[Mr.420]

I just noticed the EC probe from Bluelab isn’t on amazon or sold out, I seen it last night. But I do see others, let me look into this one and see if any other Brands are compatible.

For now this is the Bluelab web page they would be the ones to get it from.

I installed that bluelab probe into my grobo but the app continues to say it needs calibration after every time I check.

I had that same issue last year. I had to replace a circuit board.

How do you know what the ppm level should be after mixing nutes for different stages

@coffindancer

I had the same issue with a bluelabs pH probe I got off Amazon a couple months ago. I think I must have recalibrated it 10 times before it finally succeeded.

Now that’s interesting!
I’ll give it a whirl!

Well I’ll be damned, it passed the check right off the bat!

Ec probe calibration over and over

It keeps calibrating and saying it needs to be calibrated over and over. What gives?

I had the same issue with a bluelabs pH probe I got off Amazon a couple months ago. I think I must have recalibrated it 10 times before it finally succeeded. All my pH standards (7.0 & 4.0) were fresh. Maybe just keep trying to calibrate

[doverosx]

Well I’ll be damned, it passed the check right off the bat! I suspect that I didn’t let the probe reach the appropriate temperature range since it was -20C where I live.

Tip…

Make sure you leave your probe in solution for at least 5 mins even longer is better before you start calibrating… It takes a bit for probes to get stable. Make sure your solution temp is around 70 ºF temp plays a roll on Ph also
