This blend of organic acids lowers your nutrient solution's pH. It's our pH down. Don't worry if you over shoot the down: just add some Olympus Up and see the benefits of adding more calcium.
Hades Down is a pH adjusting liquid used to lower the pH of your nutrient solution. Hades Down chelates elements in the nutrient solution into stable, slow releasing forms which are easier for plants to absorb. Providing readily absorbed natural molecules, Hades Down has the ability to stimulate microorganisms and plant growth. This stimulation will directly affect increases in CO2 production, photosynthesis, beneficial microbes, and plant vigor and health. When mixing fertilizers in a reservoir, Hades Down will help prevent nutrient solution fall out.
The ideal pH for nutrient solutions is 6.2 – 6.4.
NPK = 0-1-0.
