How accurate are these ph strips?

[CF89]

Are these reliable enough to be used?

I tested my tap water and it came out at 7

I tested tap water that has sat out for a day or two in a milk jug and it was 6.75

I have not tested it after adding all my nutrients yet.

Pretty accurate. Fine for what we do.

Agreed! I just use general hydro ph drops and never have a problem either.

Id rather just stcik to my extech ph 100. Test any surface thats moist....@cemchris i dont want to hear a joke about that one!!!...there arent many direct soil ph meters on the market that cost a 100 bucks...the isfet probe meters are seriously expensive af...you are talking 800 to 1500 depending on the model....lol wtf?
