Forget About Your Old Fulvic and Humic Acid Supplements and Tap into an Even Older, Organic Source of Power... For years now we've offered you Grandma Enggy's H-2 and F-1, two revolutionary nutrient supplements derived from a single extraordinary compound called leonardite. But as you know, here at Advanced Nutrients, we never stop learning and growing in an effort to bring growers like you the very best and most fairly priced products on the market. So with this attitude in mind, we've combined these two state of the art products into one even more affordable and easy to use formula. The solution is Advanced Nutrients Ancient Earth. 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.
