Title: Phone test kit ..General hydroponics
Product review: Just a very inexpensive , accurate way to find out the ph of your water. Its easy to use color coded to insure that you are at the ph level that you desire. It has both ph up and down so up can manipulate water to get the ph you need. Just a good buy, get a kit, and you wont be dissappointed. Its worth it when you need to be accurate.
