Improve Moisture Retention and Root Growth with Vermiculite #3
The Harvest Company vermiculite #3 is a natural soil amendment designed to improve moisture retention, aeration, and nutrient availability in soil and soilless growing media. It helps create an ideal growing environment that supports strong root development, faster growth, and higher yields.
This horticultural vermiculite is suitable for both beginner and professional growers across a wide range of applications.
Enhance Nutrient Retention and Soil Performance

It can be blended with materials such as peat moss, compost, perlite, coconut coir, worm castings, and bark to create a balanced and high-performance growing mix.
