Inexpensive accurate ph wand?

Im all about cost effectiveness, but maybe i'll spend a few more bucks and get this one just in case http://www.amazon.com/Instruments-Waterproof-Meter-Temperature-Measurement/dp/B00MG3VF7Q/ref=sr_1_30?ie=UTF8&qid=1454215176&sr=8-30&keywords=ph+meter ? I mean, my concern is how can you actually know how accurate it really is if you dont have excess calibration fluid?

I calibrate mine once a month. You can get a cheap bottle of calibration solution.

something like this? http://www.amazon.com/Innovating-Science-Buffer-Calibration-Kit/dp/B00BUV7L96 seems a smidge pricey for what it is.

Yea. I use General Hydroponics. Any of that will work.

It lasts a long time though. The price you pay for your plants...

Don't like it ? Grow organic lol.

organic is more expensive. and you will still need a ph meter.

It's damn near free and ph is rather insignificant when you know what you're doing.

Costs me $30 for coco and the rest comes from kitchen scraps and manure. Doesn't get any cheaper.
