Advanced NutrientspH-Down, 4 L

Showed up day early, like how they put strong layer of tape over cap, make sure wouldn't open during shipping. Product good value for $. Only takes me a capful or 2 at most, compared to a LOT OF OTHE COMPANIES products, where have to use 5× amount!

use half as less then humbolt ph down

Best absolute bang for your buck. Last me 10 times as long as the 1 gallon general hydro pics that costs 18 dollars. So the comparison is none existent.

This product is the most concentrated and consistent pH down on the market, the rest of advanced nutrients line is straight up awful, but they make a great pH down!

I use much less of this than GH

My favorite thing about this is how potent it is. I use an eye dropper to add 4ml to a 7 gallon bucket and my PH is perfect. Bottle lasts forever!

Compared to the previous Brandi was using this one, I have to be careful to only use a tiny bit.

If you want quality product, the only way to go for the money is Advance Nutrients. I use several of their products, and no others even come close to their nutrients. Ty so much, from a very happy customer.

Very high concentrate so one jug goes a long way
