Grow Room Apera Grostar GS1 ph pen

[Guerrilla]

Anyone ever used this ph meter? No reviews on it and for $120 ish it has to be decent??

Let me know if anyone has had one or used one…
Thanks!!

I use an apera ph60 and ec60 every day. Good stuff

I too had the PH60. Two of them in fact over the years. They worked well.
