FoxFarm Bush Doctor Sledge Hammer


Sledge Hammer® nutrient rinse, from FoxFarm‘s Bush Doctor® line, is a unique rinse formula designed to remove excess fertilizer build up. High fertilizer use can compromise plant growth over time due to concentrated mineral salt deposits.

Sledge Hammer helps release surface tension in the soil which will allow for optimum absorption of moisture and nutrition throughout the plant’s root system. Derived from an extract of the Yucca Schidigera plant, Sledge Hammer is organic and can be used for both hydroponic and soil applications.
