I use the Apera Instruments AI209 PH20. Waterproof and lasts a long time as long as you take care of it. It's not too expensive either, about on Amazon.

I thank you both for the answers. Both look like good units.
But I decided to go back to the basics. ph test strips. No batteries, no calibrating.
Its funny, I use test strips to see if a meter is close. I have gone through 3 meters now so to hell with it.
Strips get me close enough.

Try Adwa ad100, with built in microprocessor. It makes readings in a few seconds, no need to wait long for taking measurements. Quite oversized in comparison with cheap ph-meters. Shows one digit after decimal point, which I found to be more comfortable for work. Really fast and precise device. Proper storage needed, as required with many other serious meters. The sensor must always be moist (some 7.0 solution in the cap). I love it

Half eaten plantWhat do y'all think is eating my plant? There's 56 out here and only the one is getting ate up🤷🤦. It's big enough to break branches. No deer around here like that I'm not close to any woods that they would come from without being seen....the plants growing great besides that.

Looking for a good sweet strainAny advise for a sweet strain with body high and euphoric effect for my next grow? I would like to grow a sweet and soft strain that just chills you out. Fast grow would be nice but I prefer to have flowering in 12/12. If it would help for headaches that's plus but not necesaryOther. Other

Separate strains separate diaries?- Should I do separate diaries for each strain? Some strains are in flower now, but I just started the diary on the day that I popped four new strains from seed. I added all strains because there is a place in the diary for other strains.
Thank you

Adjusting pH in coco coir.My pH is too high. I have Up/Down, but I don't really understand how to use it. I have one of the cheap pH testers, but I have little confidence in it. I would like to lower the pH, but I feel like 10 gallons of soil is too difficult to lower the pH since it's so much. Tips?Other. Other
