Just recalibrated mmy ph pen. It was off by 2.5. Good thing I checked it. Good idea to check once a week.

I bought a 10 dollar one on amazon, calibrated it once 6 months ago and haven't had a problem with it yet

see thats what i'm all about now. the ph pen i sold i bought for nothing and never failed me, now i'm stuck with some "brand" ph pen and keeps fucking me up! pretty sure thats why my hempy grow is failing atm!

My water is the same pH all day every day, so as long as it says 8.6 I don't worry. Been using rain water last few days, and like it. Add my nutes and only have to use .25ml of pH down, which is perfect cause I'm almost out of it and new bottle ain't here yet

I've got a Voltcraft PH-100 ATC pH Meter, superb piece of kit & very accurate. Way cheaper & better than BlueLab

Lemon juice is great to use as a PH down if you run out

I'll have to remember that about the pH down. I need to make a book with all the bits and pieces of info I've picked up here. I think my pH pen is like yours. It doesn't have a brand name, it's just yellow and says pH on it. I think the case sticker says etekcity

H-Series H280G Benchtop pH, Conductivity, DO & ISE Meter Starter Kit | Hach Canada - Overview - Obsolete

These guys make the best ph and water testers money can buy. I own 2 of these units for salt water aquariums. Got them through work.
I've compared it next to cheap eBay pens, and they were spot on for 4 days at a time. Then needed re calibration. Only off by a point or 2. 10$ vs $1500 lol

Yours sounds like the ones of *bay I've seen. If it does the job for little money, happy days. I used to have a pen but my dog chewed it so I bought the Voltcraft. It's a meter with a wand which is really handy, I leave it in my bucket when I add ph down & stir. The meter stays at the side & easy to read. I find it's much better than the old pen I had

 

[jummejum]

that yellow.. seems like the one i used to own! gonna get another 1

 

[PeytonManning]

I wouldn't even know how to use that thing. What's ISE? Stuff I never heard of that's for sure

For checking mineral content.

 

[Stumped]

That's acthualy the only part I don't use is the ise. Do is dissolved oxygen, conductivity is ec. And the rest is self explanatory

 

[PeytonManning]

Ah, so is that fancy for ppm or ec? All that stuff is way over my head. That's the stuff that turned me off from trying dwc

 

[Stumped]

I have 3 hach ec10 meeters here too, need to buy new problems for them. EBay sells cheap 20$ ones but they don't last.

 

[jummejum]

i use a cheap ebay ppm/tds and its still reliabe after 1 calibrate.

 

[Stumped]

That's the part that turned me on dwc. Then temperatures screwed me lol. I know how to read water good ( I get paid to do it) and I've been doing it for years already with aquariums. Chillers though..... Fuckin expensive. Looking at building a small chiller out of peltier plates. I really would love to never buy soil or perlite ever again

EBay ones work great. Just need calibration fluid and check it weekly. Mine drifts off a few points in a week. I've owned 4 of them they all do it. Its the pH testing method in them. The more expensive ones use a different method of testing pH. Both glass probes, but different method.

 

[Stumped]

Sorry thought u said pH. The eBay TDs pens do work great. I've calibrated mine one or 2 times since I've owned it. When I calibrated it only needed a slight adjustment.

 

[Stumped]

Peyton, I know I'm slow as old molasses, but there gonna be finished after the weekend. Have to pick more thread. And I'm going away for the weekend.

 

[PeytonManning]

It's all good, I ain't in no rush. I've got nothing but time, and am excited to get my C99 into them. Probably do my fast and vast in them first since they'll be planted about a week before pineapple chunk harvest. So no rush

see thats prolly my issue with the hempy/hydro growing, i really don't have the time to calibrate that often. :/ i wished i had more time to do so.
