I have used the same HM Digital tester for 5 years now.
Just recalibrate it once a year.
FYI, I also have their TDS meter. Works just as consistently as the PH meter.
See the link, if interested: http://hmdigital.com/product/ph-80/

Hello, but in reality I find them good as long as they are well and frequently, otherwise, there are the Apera AI221 pen tester tools, or a little more expensive Apera AI316 multi-parameter Pocket tester tools.

Hi there!
I had that bluelab and it was good, but you REALLY need to take care of your pH pens. You need to have storage solution for it or otherwise it will dry out and break. So even the meter is not good with bad maintence. And im telling you this cos I already broke 2 meters including my bluelab cos I did not use any solutions but only cleaned it with water only after use.

I also appreciate the simplicity and accuracy of PH strips when in doubt of digital meters. Cheers 🍻

Setting up air cooled refactor.I've got a new air cooled light refractor, a tube like one. I've set it up such as the pic, I'm thinking of putting the extractor where it shows on the pic with the air flow going the way of the arrow, would this be OK? I can't find anything online about setting this one up.

PH bouncing aroundDWC PH bouncing wildly. Yesterday, brought PH down from 6.4 to 5.7 using Growth Technology PH Down. Today: 6.6. Nothing added in between. Only things in DWC is air stone, nutrients, roots. What causes this? Should I worry? Tap water is soft (hardness 1.6) with a PH of 7.3.Setup. Other

Soil heaterGot a soil heater today, wrapped it around the bottom of my fabric pots. Is that the way I’m supposed to do it? There weren’t any instructions on the package & I’m not big on YouTube tutorials. Ive also been playing music for them during day light. Do any of you do this?
