    Default Soil testers

    Are these reliable for checking soil PH? For £20, I'm not hopeful but anyone know much about them?

    Any decent soil will tell you it's PH on the bag.... £20 saved

    I mean more for during a grow.

    I was away for a couple of weeks and I've run into what I believe is a PH issue. I checked the soil with a tester and I got a reading of 5.0. I flushed them 3-4x pot size last night and now they're reading 6.5.

    Just not sure how accurate they are?

    The only real way to PH test soil is with a slurry test, any other way is wildly inaccurate

    I tried one of those, it was like a random number generator every time I put it in the soil

    Have you though of doing it old school, with not litmus papers, but pH paper? they come in rolls like ribbons, or, like those roach paper booklets. Just look up "pH paper" in pictures online and you will see. They are a darker pastel amber in colour, and have a texture like thin blotting paper.

    Stick that in whatever you want to test and they give you a colour instantly, then just match that against the colour chart to find out the pH.

    They don't give a number to one decimal place, but then there is no faffing about with calibrating or cleaning.

    Hug those who care about you, do all you can for those you love (if they want it). We just never know when it might be the last time we talk to them or see them.

    i use something similar for checking my soil temps,though think mines for checking chickens n shit when cooking.

    useful to know root area temps if you grow in a shed or breadbin etc in winter.

    Yeah the other data is useful, especially if things go tits-up. Pity the ph meter is a dud.
