Hey Justlearning, good to see you around, don't be a stranger bru. All is good over here. Still rocking the 600's!!! Peace, DST
I want a faraday thingy....
I want a faraday thingy....
I noticed a couple days ago that my pH meters (Hanna continuous probes) read completely different numbers depending on whether my HID lights are on or not. Like 6.1 when the lights are on and 4.9 for example, when the lights are off. Electronic interference, anyone?
Now, I calibrate my meters when the lights are on, so does that mean they read correctly when the lights are on or are the readings total shit? BTW, the ec reading does not change, regardless of lighting, just to confound things. One would think a probe that measures electrical conductivity would be more likely to be thrown off by a strong electrical field.
3 ballasts, all digital greenhouse. 2 600 hps and a 1000k MH.
The meter is currently plugged into the same power strip as the lights, but I've plugged it into an entirely different circuit before and it was still affected.
I'd like to fix this, although I have a certain amount of faith in the lights-on reading because it obviously works really well plant-wise.
I'd like some 600 input on what I can do. Short of replacing my ballasts. Has anyone has a similar experience?
I have 15' ballast to lamp cords but the ballast to socket cord is only 6', so I can move the ballasts as far away from the meter and outlets as possible . What else can I do?
Wait! Problem solved! I just need to grow inside one of these:
