FoxFarm Bush Doctor Sledge Hammer

Sledge Hammer is a rinse formula designed to break down and flush out accumulated mineral salt deposits in your growing medium. By clearing these buildups, it prevents nutrient lockout and ensures water and nutrients can move freely through the root zone again.

It is safe and effective for both soil and hydroponic systems. Because it is derived from natural Yucca extract, it works well in various growing media without damaging your equipment or plants.

It is typically used as a maintenance tool rather than a daily additive. Many growers use it periodically throughout the growth cycle to prevent salt buildup, or specifically when they notice signs of nutrient lockout or slow water drainage.

Sledge Hammer is designed to target mineral salt buildup, not necessarily strip all nutrients from your soil. However, it is a powerful rinse, so you should follow the recommended application rates to avoid over-flushing your medium.

No, the active ingredient is Saponin, which is derived from Yucca Schidigera extract. It acts as a natural surfactant to help water penetrate and flush the medium effectively.
