Dutch Nutrient pH Down 85% Phosphoric Acid - 500 ML

Awesome product and great seller. This is by far the strongest pH down I've ever bought, so be careful because a few drops do a lot! It shipped way faster than expected and was packaged perfectly to make sure the bottle didn't break. Highly recommend!

Strongest product i've used.

super fast shipping, got this in 2 days. cheapest i can find.
