Does anyone have a recommendation for a decent ph ec meter?
I use ph drops.
I have a ph meter, and if I'm doing a BUNCH of stuff, like if I'm working on my hydroponic garden outside in the summer and I'm mixing up 100+ gallons in different buckets, then I use it.
But its a pain in the ass to keep calibrating it every few weeks and I always question how accurate it is after a few days because mine always seems to get wonky.
I use the General Hydroponics PH drops. They don't need calibrated, always work, don't run out of batteries, etc. Plus I get to feel like a chemist when I'm using them.
