Benedict SmartMix®5 LIGHTWEIGHT PLANTER BOX MIX (HORIZON B)

The B Horizon (below 300mm) in a Planter Box Soil Profile, needs a free draining, non-slumping material, that has very low organic matter levels. The need for low organic matter exists because below 300mm gas exchange with the air ceases and organic matter will begin producing phytotoxic gases as a result of anaerobic conditions.
