Easy, Precise pH Control for Healthier Plants!
This Bloom City pH Up + Down kit is a must-have for anyone serious about maximizing nutrient uptake in their hydroponic or soil-based grow. The bottles are clearly labeled, easy to pour, and work fast—just a few drops go a long way. What I love most is the precision and consistency. Whether I’m adjusting water for veggies, herbs, or houseplants, this kit helps me dial in the perfect pH range every time. No residue, no weird smell, and it mixes well. You get both solutions in one affordable pack, and the 16 oz total lasts longer than I expected. Definitely recommend for beginner and experienced growers alike!

Perfect for Hydroponic Farming

Works very well
Works SUPER well. The up is definitely more strong then down so be careful. Besides that it’s very good. No leakage at all, the size is very good, it’ll last a while. Super easy to use. You should wait about 5 minutes after change the ph then test. Ph stabilizes well with this kit and very fast. It does come in this little bag which is nice.

A lifetime supply?
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. :)

Works well
Been using these for my new hydroponics hobby. Doesn't take but a few drops of either of these to significantly alter the PH 1-2 levels in either direction for a half gallon batch of nutrient solution. Will likely take me a long time to use all of it. Good value.
