Foxfarm - Sledge Hammer 1 Litre



Nutrient Rinse. FoxFarm SledgeHammer is a natural and organic liquid blend designed to remove excess fertilizer build up in established gardens, container plantings and in hydroponic systems. Over time high fertilizer use can compromise plant growth due to concentrated mineral salt deposits.

Sledge Hammer encourages water movement through soil and soilless mediums and helps release surface tension which will allow optimal absorption of moisture and nutrition through the plant’s root system.
