FoxFarm Bush Doctor Sledgehammer | 1gal - OMRI Listed - (Case of 4)

OMRI-Listed Saponin Rinse for Mineral Salt Buildup, 1gal

Heavy fertilizer use over a growing cycle can leave mineral salts concentrated in the root zone, a buildup that a standard watering doesn't fully clear. FoxFarm Bush Doctor Sledgehammer is a rinse formula derived from saponin, an extract of the yucca plant, designed to encourage water movement through soil and soilless media so those deposits flush out rather than accumulate.

The 1gal case of 4 is sized for retailers or larger grow operations that flush regularly and need a consistent bulk supply.

Key Features & Benefits

• Derived from saponin — a naturally occurring extract of the yucca plant rather than a synthetic surfactant.

• Encourages water movement through media — helps flush accumulated mineral salts rather than letting them concentrate further.

Who Should Use Sledgehammer

Growers running high-fertility feeding programs who need to periodically clear mineral salt buildup from the root zone are the fit for Sledgehammer.

Frequently Asked Questions

What is Sledgehammer made from?

It's derived from saponin, a naturally occurring extract of the yucca plant, rather than a synthetic surfactant or detergent. That plant-derived origin is part of why it carries OMRI Listing.

When should I flush with Sledgehammer?

It's typically used when mineral salt deposits have built up from heavy fertilizer use, though some growers also work it into a regular periodic flush schedule. Either approach clears deposits before they concentrate further in the root zone.

Is Sledgehammer certified for organic use?

Yes, it's OMRI Listed. That makes it eligible for use in certified organic cultivation programs alongside conventional ones.

What growing media can Sledgehammer be used with?

It's designed for soil, soilless mixes, and other common growing media. The saponin rinse works the same way across all of them, encouraging water movement to flush accumulated salts.
