Bloom City Professional pH Up + Down Control Kit for Optimal Nutrient Uptake (Two 1/2 Pint Bottles) 16 Total oz

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!

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.

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. :)

Exactly as promised.

Been using last couple grows. Does well. Definitely keeps the ph balanced Lasts pretty long. Small bottle. No leaks.

These meet the need perfectly. That said, it's critical to have an accurate Ph meter and, especially, to only adjust Ph in one direction by applying a small amount at a time when first starting out. It really helps to have a source of RO water to start with because true RO water is Ph 7.00. RO is also free of minerals and salts which can act as a buffer, rendering the Ph Up/Down solutions ineffective. Bottom line: These Ph Up/Down solutions are highly recommended provided a Ph neutral water source is used, an accurate and calibrated Ph meter is available, and Ph is only adjusted in one direction.

Must have

It needs more then 1ml per gal but it does the job
