Grump's Kitchen Sink Grow 🌱

There's not much on the market that I know of that seem to be as reliable, without dropping thousands on lab-grade equipment or making your own

I'd like to have live monitoring 24/7 too next time I do dwc

I just have the pH and E.C pens for now

Moe had all that atlas equipment that he bought new and after a grow or two he already started having issues.. i bought that dfrobot ph sensor, the best one they offered, less than a year later and now it won't calibrate anymore and i've tried factory resets and all kinds of tries.. nothing works, it's useless to me right now. it's why i went ebay hunting for the bluelabs in the first place!

I leave mine in 24/7 and only need to recal once every 3 months for new grow. I compare against ph stick pen to make sure every 2 weeks, but it's always right on.

From the little i know, if you want to leave in solution 24/7 you absolutely have to have a double junction probe, which means the inside is contained in it's own solution, not directly in the testing environment. This means the reading is a little slower on a fast change reading but much more reliable.

What is the difference between a single & double junction probe?

The reference cell of a single junction probe has a wick or frit that makes direct contact with the solution being measured. This is an essential component that allows the probe to function. Contamina

A year is usually all a mfg will say they last if suspended 24/7 in solution. I get 2 years from the apera double junction, and for $40 i think it's a bargain

I’ve got one that separates using a bnc connection. I use it to check the other cheap ones I have.
