Bush Doctor® SledgeHammer® encourages water movement through soil and soilless media.  High fertilizer use can compromise plant growth over time due to concentrated mineral salt deposits. SledgeHammer® is a unique rinse formula designed to remove fertilizer buildup which may relieve nutrient lockout. Derived from saponin, an extract of the Yucca schidigera plant. SledgeHammer® is designed for organic gardening and can be used for both hydroponic and soil applications.
