ViagrowVPTK4 Complete Testing & Adjusting, pH Control, Crystal Kit, Clear

I use it to measure my drinking water it seems to give accurate reading of course I can’t know for sure but it gives me enough info as to when to change my alkalinizer sticks!

If you used other ph down with very little effectiveness, you need to try this. It brings down your ph ;evel at a very small dose. This stuff is highly efficient for the cost.

Not prime but faster than estimated date.. much needed organic ph buffer.. next update on how it works for my water!

Going to start most of my garden vegetable plants early indoors, in a sunroom, but the water here is very high in alkalinity. This kit solves that issue.

This stuff works as designed. Problem is, it takes way too much to make a very small difference in overall PH. This is a viable option for a small farmer with 1-3 plants to ph water for. Not so much for larger quantities.

Easy to use

I have really enjoyed this test kit!It has everything you need for your ph. So far I have had really good luck. My water is very hard, very acidic. All my plants are growing awesome in their hydroponic home. This kit is so much easier then calibrating a ph meter.

Got New bottles that aren't even half full but they are sealed. Guess it's just like a bag of chips, half air
