urinary tract infection baking soda

I've used it one time and it was very effective. Since purchasing this kit I've read a book on beginning hydroponics--apparently you can use vinegar to lower the PH and baking soda to raise it it you don't want to spend the money on this kit.

I bought this pH test kit instead of a digital pH meter. A good digital pH meter is fairly expensive and a cheap meter could have questionable accuracy. Plus, I have had experience using digital pH meters at work a few years ago, and they are just hard to deal with, not as far as using them, they are easy to use to test the pH of something, but they can easily fall out of tolerance and need to be calibrated, you don't necessarily know when the reading is off and it needs to be calibrated, as in the pH measurements you've been getting were wrong for a while and you didn't know it, the probes have to be kept wet or not depending on the model of meter, not to mention they are a sensitive electronic device and you have to just be careful with them.

So therefore, I got this pH test kit and it works great. Sure, it's a regular test kit and doesn't give you the absolute exact pH like a meter would, but if you need the pH of something to be in a particular range, as in water... Read more

Works very well in controlling ph levels in soil and hydro setups. The color chart and indicator solution are very easy to work with. Takes me an extra 1 minute or less to adjust ph of nute solution. Good stuff. Consider the soluble powder version of the up and down if you want it to last longer. Also you get more for less shipping
