Ph Down by Hesi, is an acidity corrector to the nutrient solutions for plants in growth phase. It's suitable for both hydroponics and aeroponic crops. 

This high quality product manufactured by the Dutch company Hesi, which guarantees its effectiveness. Marijuana plants have difficulty assimilating nutrients due to a poorly regulated pH, and are more prone to disease and pest attacks. We therefore advise you to use Hesi pH-Down to reduce the pH value in the final nutrient solution for growing plants.

It must also be stressed that this product should only be used for the growth phase, since it is formulated with pH regulators that provide nitrogen in a nitric form.

Having to high the pH level may generate combinations of insoluble elements.

This product helps to lower the pH by adjusting it so that the plant develops perfectly during its growth phase.
