Organically inclined? This is a combo – Fulvic and Humic acid nutrient supplement product. It reduces salinity effects and helps stabilize pH, avoiding stressful fluctuations. The product is designed to make your plants yield at maximum levels by increasing their nutrient uptake (particularly of micronutrients). The main selling point is that by buying this, you don’t have to go out and purchase separate humic and fulvic acid products (both of which ADVANCED NUTRIENTS will happily sell you, btw.) Ancient Earth is in the company’s “organics” line. The product comes in 1L, 4L and 10L bottle sizes, and it is specifically designed to work in all hydroponics mediums as well as soil. For use during the entire vegetative and flowering grow cycles.
