Sledge Hammer helps rinse out mineral salt build up and encourages nutrient lock up which will allow for optimum absorption of water and nutrients throughout the plant's root system.  Over fertilizing can compromise plant growth over time due to concentrated mineral salt deposits, where Sledgehammer can alleviate these conditions. Sledgehammer is derived from an all natural extract of Yucca schidigera.  Saponin 10% and is organic.  Mix 2 teaspoons per gallon of fresh water for in-ground plantings. 

2 drops per gallon of fresh water for hydroponic recirculating systems.
