FoxFarm Bush Doctor Sledgehammer | 16oz -OMRI Listed

Yucca-Derived Rinse Formula for Salt Build-Up, 16oz

Heavy fertilizer use over a season leaves mineral salts behind in soil and soilless media, and those deposits can interfere with water movement and nutrient uptake if they're never cleared. FoxFarm Bush Doctor Sledgehammer is an OMRI Listed rinse formula derived from saponin, an extract of the yucca plant, that encourages water to move through the media and helps address that salt build-up.

The 16oz size suits growers running Sledgehammer as an occasional flush rather than a routine, high-volume application.
