About Us

Green Grove Soil Factory supplies highly porous agricultural volcanic tuff in 0–4 mm and 10–25 mm grades. Our technical positioning focuses on root-zone engineering rather than direct fertilization.

The product's primary value comes from improving the balance of air, water, drainage, and structural stability within the growing medium. The fine and coarse grades therefore serve different agricultural functions even though they come from the same mineral raw material.

This makes the product suitable for growing mixes, grow bags, greenhouses, granular media, aquaponics, and landscaping according to particle size and application method.

Our Product — Green Grove Volcanic Soil

0–4 mm is designed for building growing media, supporting moisture management, improving agricultural mixes, and modifying the root zone in soil or grow bags.

10–25 mm is designed for aeration, drainage, and structural stability. It performs well in granular systems, aquaponics, coarse mixes, and durable surface cover when matched correctly to system design, irrigation, and water conditions.
