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 enhance plant growth. This stimulation will directly increase the population of beneficial microbes, which will increase plant nutrient availability and uptake. When mixing fertilizers in a reservoir, Hades Down will help prevent nutrient solution fall out.
