### ⭐⭐⭐⭐⭐ A lifetime supply?
*by S***Y on July 22, 2023*

This stuff works great to keep my PH where my plants like it. My only issue is that it takes such a tiny amount of the product (we're talking just a drop or two in a two gallon bucket of water for me) that I inadvertently put in too much of one, then have to compensate with some of the other. This isn't a complaint, these two bottles will last me a lifetime at this rate & I'm ok with that. Sometimes I need such a small amount that I just need to put my knife in the bottle to get it slightly wet with the PH Up or Down, and then stir the water in my 2 gallon bucket with the knife to correct the PH. Great stuff, I would just recommend buying an eye dropper to use with it to control the amount and for the love of god, if this is your first time using it start off with just a drop or two per 2 gallon bucket. You're welcome. :)
