This kit is very easy to use. Even the labeling is simple, very minimalist. This kit will also last a very long time considering it only takes several drops to adjust water ph. I don’t rely on the ph tester included in the kit, nevertheless, I still use it every time I test my water ph. I first use a digital ph meter, then I use the liquid tester that comes with the kit for a “second opinion”. Works pretty well!

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

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.
