The Harvest Company Viagrow premium coarse vermiculite is a natural soil amendment designed to improve moisture retention, aeration, and nutrient delivery in potting mixes and growing media. Its coarse structure helps create better airflow in the root zone while holding essential moisture for consistent plant growth.
This high-quality vermiculite supports stronger root development, faster growth rates, and higher yields.
Enhance Nutrient Retention and Soil Performance
