What is an affordable way to measure PH accurately...

Hi. well ive bought kinda cheap ph meter for my grows, and used it for aaaam i would say 3 times. i was so worried of that ( i used it wrong) that i nearly killed one plant ( my first indoor grow) after that i never usd a ph meter, Because i used a very balanced soilmix, and used to fetilise very less. Soil buffers very well ph fluctuations. So i never take care of Ph in my Grows ( Pls dont tell it anybody)

You can get the whole general hydroponics control kit for about $16 on amazon. The colors are clear and easy to read. That is what I use. Whatever you do stay away from test strips. They are hard to read. Hope this helps!

You can grab ph test strips u can find them cheap in most pool sections... it won't give u down to the decimal point but good enough to know if your in the right range!
