Unlike coco coir or peat-based options, this inert mat avoids nutrient lockout or pH variation. It enables faster crop turnaround while remaining completely compostable after use. As an agrotextile, it aligns with organic growing standards and is safe for use in food handling areas.
This garden substrate also supports plant uniformity and reduces microbial build-up compared to spongy or cellulose-based mats. With no pre-treatment required, it's ready to use straight from the roll—simply place in trays, add water and seed directly.
