We combined fulvic and humic acids into a single nutrient formula that was specifically designed to fit the needs of the valuable plants we grow. Ancient Earth reduces the effects of salinity and pH fluctuations, increases your plants' uptake of the precious micronutrients that drive your plants to reach their optimum yield. Plus, you get double the value, because this one formula replaces two products previously sold separately. This is a no brainer. And since this, like all of our products, is backed by our money back guarantee, you really have nothing to lose and everything to gain by trying Ancient Earth today.
